Dear colleagues,

With great sadness, I share the news of the passing of Misha Blagosklonny, an extraordinary scientist whose highly original contributions significantly advanced cancer and aging biology research. Roswell was fortunate to have him as a faculty member in the Department of Cell Stress Biology during several exceptionally productive years, during which he published over 100 papers. Misha was also widely known as the founding editor of several prominent peer-reviewed journals, including Cell Cycle, Oncotarget, Oncoscience, and Aging.

He was always a visionary thinker, often ahead of his time, with ideas that pushed the boundaries of our field. Tragically, Misha succumbed to metastatic cancer after about two years of remission following an initial positive response to targeted therapies. Even in his final days, he continued to collaborate actively and creatively with his physicians, as evidenced in his thoughtful posts on X (https://x.com/blagosklonny?lang=en).

Misha will be remembered as one of the most uniquely gifted oncologists of our time.

For more details about his professional life, please visit: Dr. Blagosklonny.

Sincerely,

Andrei

Dr. Wafik S. El-Deiry reflects on his decades-long friendship and collaboration with Dr. Mikhail (Misha) Blagosklonny in a tribute posted on OncoDaily.

This evening, a number of close friends and colleagues came together in Boston for a few hours to remember and pay tribute to Dr. Mikhail Blagosklonny, MD, PhD, who left us a few weeks ago after courageously battling lung cancer with brain metastases for two years.

Misha had a remarkable and rare intellect that impacted on thought in the field of aging and cancer over the last 30 years. His impact on us was not only in science, but also in scientific publishing as well as the way he conducted himself as a humble, thoughtful, and kind human being with a smile on his face.

I was fortunate to know him for almost 30 years since he worked in my laboratory at the University of Pennsylvania and HHMI for a couple of years in the mid 1990’s after coming from NCI where he was a Fogerty Fellow. In the lab, he was creative, gifted as a scientist both intellectually and technically and was intense in his pursuit of answers.

Over the last couple of decades we interacted in our work in scientific publishing (Cancer Biology and Therapy, Cell Cycle, and Oncotarget) and in recent months as one of the physicians who cared for him.

I can say that his knowledge of science and medicine was profound. As this relates to cancer I think he knew more than any of his physicians and came up with strategies that ultimately prolonged his life much longer than would have been expected. Some of this was also due to input by @Dr_R_Kurzrock and later through the @WIN_Consortium MTB where he personally attended the discussion.

It was an honor to know him for the last 3 decades and I for one will miss him and will always remember him. I am proud of what he accomplished, will personally follow through on what he started and achieved with @Oncotarget @OncotargetJrnl, and will honor his legacy.

Associate Dean for Oncologic Sciences at the Warren Alpert Medical School and Director of the Legorreta Cancer Center at Brown University and Director of the Joint Program in Cancer Biology at Brown University and affiliated hospitals. He is the Editor in Chief at Oncotarget. Dr. El-Deiry discovered p21(WAF1) as a p53 target gene, cell cycle inhibitor, and tumor suppressor that explained the mammalian cell stress response. Dr. El-Deiry’s research is focused on mechanisms of therapy resistance with major efforts in drug discovery and development.

Barzilai DA. Mikhail ‘Misha’ Blagosklonny’s enduring legacy in geroscience: the hyperfunction theory and the therapeutic potential of rapamycin. Aging (Albany NY). 2025;:17:1-15. doi: 10.18632/aging.206189 [PubMed]

The untimely passing of Dr. Mikhail “Misha” Blagosklonny has left a lasting void in geroscience and oncology. This review examines his profound contributions, focusing on his pioneering the Hyperfunction Theory and his advocacy for rapamycin, an mTOR inhibitor, as a therapeutic agent for lifespan extension. Contrary to traditional damage-centric models, the Hyperfunction Theory rejects damage accumulation as the primary driver of aging. Instead, it redefines aging as a quasi-programmed process driven by the persistent, excessive activity of growth-promoting pathways beyond their developmental roles, leading to age-related pathologies. We explore how Blagosklonny’s insights predict rapamycin’s ability to decelerate aging by modulating excessive mTOR signaling, supported by empirical evidence across multiple physiological systems, including immune, cardiovascular, cognitive, and oncologic health. His forward-thinking approach, advocating for the cautious clinical use of rapamycin and suggesting personalized, preventive, and combination therapy strategies, has catalyzed interest in translational geroscience. This review synthesizes Blagosklonny’s legacy, presenting rapamycin as a foundational pharmacological intervention with potential in managing age-related decline and extending healthspan, and underlines his impact in shifting aging research from theoretical frameworks to actionable interventions. Blagosklonny’s work remains an enduring inspiration, paving the way toward treating aging as a modifiable condition.
