The Unexpected Link Between Cancer, Wound Healing, and the Protein SerpinB3

For decades, SerpinB3 has been flagged as a danger signal – a protein whose presence often indicated aggressive cancer. Now, a groundbreaking study from Arizona State University reveals a surprising twist: this same protein is a crucial player in the body’s natural wound-healing process. This discovery isn’t just rewriting our understanding of SerpinB3; it’s opening doors to potentially revolutionary treatments for chronic wounds and, paradoxically, more effective cancer therapies.

The Dual Life of SerpinB3: From Cancer Marker to Healing Agent

Researchers led by Jordan Yaron and Kaushal Rege at ASU’s Biodesign Center for Biomaterials Innovation and Translation found that when skin is injured, cells flood the wound site with SerpinB3. This surge isn’t a sign of something gone wrong, but rather a deliberate activation of the body’s repair mechanisms. The protein, also known as squamous cell carcinoma antigen-1, was first identified in 1977 in cervical cancer tissue and has since been linked to aggressive forms of lung, liver, and skin cancers. High levels have consistently correlated with poorer patient outcomes.

“For more than four decades, SerpinB3 has been recognized as a driver of cancer growth and metastasis,” explains Yaron. “Yet after all this time, its normal role in the body remained a mystery. But when we looked at injured, healing skin, we found cells producing enormous amounts of this protein. It became clear that this is part of the machinery humans evolved to heal epithelial injuries, a process that cancer cells have learned to exploit to spread.”

How SerpinB3 Supercharges Wound Repair

The ASU team discovered that SerpinB3 activates keratinocytes – the skin cells responsible for closing wounds. By making these cells less “sticky” and more mobile, SerpinB3 allows them to migrate more efficiently across the wound bed, rebuilding tissue. In lab tests, adding extra SerpinB3 accelerated wound closure at a rate comparable to epidermal growth factor, a commonly used healing booster. Furthermore, the protein helps organize collagen fibers, providing a stronger, more structurally sound repair.

This isn’t just about speed; it’s about quality. The neatly arranged collagen fibers resulting from SerpinB3 activation contribute to the skin’s overall strength and integrity, potentially reducing the risk of scarring and long-term complications. The research, published in Proceedings of the National Academy of Sciences, builds on previous work exploring bioactive nanomaterials for wound repair, revealing how these materials can amplify the body’s natural healing signals – and highlighting SerpinB3 as a key component of that response.

The $20 Billion Wound Care Challenge and the Promise of SerpinB3

The implications of this research are significant, particularly considering the scale of the wound care challenge. An estimated 6 million wounds occur annually in the U.S., with a substantial portion becoming chronic and difficult to treat. These hard-to-heal wounds, often linked to diabetes, burns, infection, or age, carry an estimated $20 billion price tag each year. Developing therapies that accelerate and improve wound healing could dramatically reduce both human suffering and economic burden.

Beyond Wound Care: Targeting SerpinB3 in Cancer

The dual nature of SerpinB3 presents a fascinating therapeutic opportunity. While boosting its activity could accelerate wound healing, blocking it might offer a novel approach to combating aggressive cancers. Cancer cells, it turns out, hijack the protein’s wound-healing properties to facilitate their own spread and metastasis. By disrupting this process, researchers hope to develop new strategies to contain and eliminate cancerous tumors.

Further research is needed to fully understand SerpinB3’s complex role in inflammatory conditions like skin diseases and asthma. The protein’s involvement in regulating tissue breakdown and repair suggests it could be a key player in a wide range of pathological processes. The National Cancer Institute provides comprehensive information on cancer research and treatment.

The Future of Regenerative Medicine: A Systems-Level Approach

The ASU study underscores the importance of viewing the body not as a collection of isolated systems, but as an integrated network. Understanding how proteins like SerpinB3 function within this network – and how they can be manipulated to promote healing or suppress disease – is crucial for advancing regenerative medicine. The convergence of biomaterials science, protein engineering, and systems biology is paving the way for a new era of targeted therapies that harness the body’s inherent healing capabilities.

Cutting Dialysis Times by 90 Minutes Could Be the Key to Saving Lives in Metformin-Associated Lactic Acidosis

Every year, thousands of people with diabetes rely on metformin to manage their blood sugar. But a rare, yet potentially fatal, side effect – metformin-associated lactic acidosis (MALA) – looms as a serious threat. New research, presented at ASN Kidney Week 2025, reveals a surprisingly simple, yet profoundly effective, intervention: a standardized protocol for rapid diagnosis and, crucially, faster access to dialysis. This isn’t just about tweaking existing procedures; it’s a potential paradigm shift in how we treat this life-threatening condition.

The Silent Threat of MALA: Why Speed Matters

Metformin-associated lactic acidosis occurs when lactic acid builds up to dangerous levels in the body, often triggered by kidney problems or other underlying health issues in individuals taking metformin. The condition can rapidly lead to organ failure and death. Historically, diagnosis has been delayed, and treatment – primarily dialysis – hasn’t been initiated quickly enough. This delay is where the new research makes a significant impact. Understanding diabetes management and potential side effects is crucial for both patients and healthcare providers.

Thailand’s Success Story: A Protocol for Survival

Researchers in Thailand implemented a standardized MALA protocol at Maharat Nakhonratchasima Hospital (MNRH). This protocol focused on three key areas: rapid diagnosis, immediate access to dialysis (including intermittent hemodialysis, continuous kidney replacement therapy, and peritonealdialysis), and increased staff awareness. The results were striking. Before the protocol, the 30-day mortality rate for MALA patients at MNRH was 25.7%. After implementation, that rate plummeted to 13.9% – nearly a 50% reduction.

Contrast this with Burirum Hospital (BH), which did not adopt the protocol. Their 30-day mortality rate remained stubbornly high, fluctuating between 27.2% and 30% over the same five-year period. The difference wasn’t just statistical; it was a real-world demonstration of the protocol’s life-saving potential. The average “door-to-dialysis” time – the critical window between hospital admission and the start of dialysis – was slashed from 870 minutes to 690 minutes at MNRH.

The Power of Awareness and Preparedness

Beyond faster dialysis, the protocol significantly boosted MALA awareness among hospital staff, jumping from 38.5% to 89.9%. This increased awareness likely contributed to quicker diagnosis and more efficient treatment pathways. As Dr. Watanyu Parapiboon, the study’s corresponding author, emphasized, “Fast-track dialysis pathways should be adopted for time-sensitive conditions like MALA.”

Looking Ahead: Global Implications and Future Trends

The findings from Thailand have significant implications for healthcare systems worldwide. While metformin is a widely used and generally safe medication, the risk of MALA, however small, demands proactive preparation. Several key trends are likely to emerge in the coming years:

• Wider Adoption of Standardized Protocols: We can expect to see more hospitals and healthcare networks adopting similar MALA protocols, prioritizing rapid diagnosis and dialysis initiation.
• AI-Powered Early Detection: Artificial intelligence and machine learning could play a role in identifying patients at high risk of MALA, allowing for earlier intervention and preventative measures. Algorithms could analyze patient data – including kidney function, medication history, and other health indicators – to flag potential concerns.
• Telemedicine and Remote Monitoring: Telemedicine could facilitate faster consultations with specialists and expedite the decision-making process for dialysis initiation, particularly in remote or underserved areas.
• Personalized Dialysis Approaches: Research may refine dialysis protocols based on individual patient characteristics, optimizing treatment effectiveness and minimizing complications.

The success in Thailand underscores a critical point: in time-sensitive medical emergencies like MALA, every minute counts. Investing in standardized protocols, staff training, and rapid access to dialysis isn’t just good medicine; it’s a matter of life and death. The future of MALA treatment isn’t about finding a new drug; it’s about optimizing the speed and efficiency of existing care pathways. What steps will your local hospital take to improve MALA outcomes?

The Silent Shift in Kidney Health: Why AKI Mortality is Rising in the Wealthiest Nations

Despite overall global stability in acute kidney injury (AKI) related deaths, a new five-year study reveals a stark divergence: while mortality rates are falling in lower-income countries, they are quietly rising in wealthier nations. This isn’t a story of worsening healthcare, but a complex interplay of aging populations, increasing chronic disease, and the hidden vulnerabilities of advanced economies. The findings, presented at ASN Kidney Week 2025, demand a re-evaluation of how we approach kidney health worldwide.

Global Trends: A Tale of Two Worlds

Researchers at Kyung Hee University Hospital in Seoul analyzed data from 43 countries spanning 1996 to 2021, uncovering a surprising trend. While acute kidney injury mortality remained relatively stable globally, high-income countries experienced a gradual increase, while low- and middle-income countries saw a decline. This isn’t simply about access to care; it’s about the changing face of illness itself.

The Aging Factor: A Demographic Time Bomb

The primary driver of rising AKI mortality in high-income nations is population aging. As people live longer, they accumulate more comorbidities – conditions like diabetes, heart disease, and hypertension – all of which significantly increase the risk of AKI. Older adults are also more vulnerable to the effects of AKI, making them less likely to recover fully. This is particularly pronounced among women, the study found, suggesting potential sex-specific biological or healthcare access factors warranting further investigation.

Improvements in Lower-Income Countries: A Success Story

The decline in AKI mortality in low- and middle-income countries is a testament to progress in infection control and healthcare access. Better sanitation, improved access to antibiotics, and earlier intervention for common infections are all contributing factors. A younger population profile also plays a role, as younger individuals are generally more resilient to AKI and have fewer pre-existing conditions. However, it’s crucial to remember that these gains are fragile and require sustained investment.

Looking Ahead: Projections to 2050

The study doesn’t just analyze the past; it projects into the future. Researchers predict a gradual rise in global AKI-related mortality through 2050, driven primarily by the continued aging of populations in high-income countries. This projection underscores the urgent need for proactive strategies to mitigate the coming burden.

The Comorbidity Conundrum

The increasing prevalence of chronic diseases isn’t just a demographic issue; it’s a physiological one. Comorbidities create a vicious cycle, increasing the risk of AKI, and AKI, in turn, can exacerbate existing conditions. Managing these complex interactions will be critical in preventing AKI and improving outcomes. For example, patients with both diabetes and heart failure are at significantly higher risk of developing AKI than those with either condition alone.

What Can Be Done? Tailored Strategies for a Changing Landscape

The study’s authors emphasize the need for tailored strategies, recognizing that a one-size-fits-all approach won’t work. High-income countries need to focus on preventative care for older adults, early detection of kidney disease, and improved management of comorbidities. This includes promoting healthy lifestyles, regular kidney function screenings, and optimizing medication regimens to minimize kidney toxicity. Low- and middle-income countries must continue to strengthen their healthcare infrastructure and expand access to essential medicines and services.

Further research is essential to understand the specific factors driving these trends and to evaluate the effectiveness of different interventions. Continuous monitoring of AKI-related mortality is also crucial to track progress and identify emerging challenges. The American Society of Nephrology is a leading resource for information on kidney disease and research.

The future of kidney health isn’t predetermined. By understanding the shifting patterns of AKI mortality and investing in targeted strategies, we can protect vulnerable populations and ensure that everyone has access to the care they need. What steps will policymakers and healthcare systems take to address this silent shift?

Could a New Risk Score Revolutionize Kidney Transplant Waitlisting?

Every 14 minutes, someone in the US is added to the kidney transplant waiting list. But a surprising number never receive the life-saving organ they need. Current waitlisting practices, relying heavily on a single measure of kidney function, may be missing a critical opportunity to identify and prioritize patients who would benefit most from a transplant – and a new study suggests a way to change that.

The Limitations of eGFR: A One-Size-Fits-All Approach

For years, the primary criterion for kidney transplant eligibility has been an estimated glomerular filtration rate (eGFR) of 20 ml/min/1.73 m² or less. While eGFR provides a snapshot of current kidney function, it doesn’t predict future risk. This means individuals with similar eGFR levels can have vastly different trajectories of disease progression. A younger patient with rapidly declining kidney function might be overlooked while an older patient with a stable, but low, eGFR is prioritized – a scenario that doesn’t always align with maximizing patient benefit.

Introducing the Kidney Failure Risk Equation (KFRE)

Researchers are now exploring a more nuanced approach, incorporating the kidney transplant waitlist with the Kidney Failure Risk Equation (KFRE). The KFRE, presented at ASN Kidney Week 2025, calculates a patient’s two-year risk of kidney failure based on four key factors: age, sex, urine albumin levels, and eGFR. This provides a more comprehensive assessment of individual risk, moving beyond a single point-in-time measurement.

How Does KFRE Compare to Current Practices?

A study analyzing data from over 10,000 US veterans with chronic kidney disease revealed significant differences between the two criteria. While 60% of patients met both the current eGFR threshold and a KFRE score of ≥25% risk, a substantial 20% qualified under only one. Notably, those qualifying solely based on KFRE were, on average, 18 years younger than those qualifying solely on eGFR (53 vs. 71 years). This suggests the KFRE could identify younger patients at high risk who might otherwise be delayed in the listing process.

Addressing Racial Disparities in Transplant Access

Perhaps even more compelling, the KFRE appears to have the potential to reduce racial disparities in access to kidney transplantation. The study found that using the KFRE criteria alone would lead to more males, and importantly, more individuals from minority groups – including Hispanic, Black, and Asian populations – being added to the waitlist. These groups often experience higher rates of kidney disease progression and historically have faced barriers to accessing transplantation. This isn’t simply about adding names to a list; longitudinal data (2006-2019) showed that patients identified by both criteria or KFRE alone experienced higher rates of successful transplants and lower mortality rates compared to those listed solely on eGFR.

The Role of Albuminuria and Diabetes

The inclusion of urine albumin levels in the KFRE is particularly significant. Albuminuria, the presence of protein in the urine, is an early indicator of kidney damage and is more prevalent in individuals with diabetes – a major risk factor for kidney failure. By factoring in albuminuria, the KFRE provides a more sensitive measure of kidney health, especially for those with diabetes and other comorbidities.

Looking Ahead: Personalized Transplantation and Predictive Modeling

The shift towards incorporating risk prediction into waitlisting criteria represents a broader trend in medicine: personalized care. Instead of treating all patients with the same diagnosis identically, clinicians are increasingly using data-driven tools to tailor treatment plans to individual needs. The KFRE is a prime example of this approach, leveraging predictive modeling to optimize the timing of kidney transplantation.

However, the KFRE isn’t a perfect solution. Further research is crucial to validate its effectiveness in diverse populations beyond veterans and to refine the risk thresholds. The University of Michigan team, led by Jennifer L. Bragg-Gresham, MS, Ph.D., is actively pursuing these investigations. The future of kidney transplantation may well involve even more sophisticated risk assessment tools, incorporating genetic factors, biomarkers, and lifestyle data to create a truly individualized approach to waitlisting and allocation.

What impact will these changes have on the lives of those waiting for a kidney? The potential to save more lives and reduce health inequities is substantial. Share your thoughts on the future of kidney transplantation in the comments below!
