“Combating osteoporosis and obesity with exercise: leveraging cell mechanosensitivity”

Center for Biotechnology Director Dr. Clinton Rubin has co-authored a recent article published in Nature Reviews Endocrinology ““Combating osteoporosis and obesity with exercise: leveraging cell mechanosensitivity”.  Abstract below, full article here.

Abstract: 

Osteoporosis, a condition of skeletal decline that undermines quality of life, is treated with pharmacological interventions that are associated with poor adherence and adverse effects. Complicating efforts to improve clinical outcomes, the incidence of obesity is increasing, predisposing the population to a range of musculoskeletal complications and metabolic disorders. Pharmacological management of obesity has yet to deliver notable reductions in weight and debilitating complications are rarely avoided. By contrast, exercise shows promise as a non-invasive and non-pharmacological method of regulating both osteoporosis and obesity. The principal components of exercise — mechanical signals — promote bone and muscle anabolism while limiting formation and expansion of fat mass. Mechanical regulation of bone and marrow fat might be achieved by regulating functions of differentiated cells in the skeletal tissue while biasing lineage selection of their common progenitors — mesenchymal stem cells. An inverse relationship between adipocyte versus osteoblast fate selection from stem cells is implicated in clinical conditions such as childhood obesity and increased marrow adiposity in type 2 diabetes mellitus, as well as contributing to skeletal frailty. Understanding how exercise-induced mechanical signals can be used to improve bone quality while decreasing fat mass and metabolic dysfunction should lead to new strategies to treat chronic diseases such as osteoporosis and obesity.

As we age, changes in our “epigenome” alter how our genes are regulated, ultimately impacting organ function. Our research focuses on understanding epigenomic changes in different organs. In this presentation, I will focus on skeletal muscle, which makes up 40% of our body weight and plays a key role in metabolism. As we age, our muscles tend to weaken, partly because the stem cells in our muscles that help repair and grow reduce in number and function. In our study, we looked at muscle stem cells from young, old, and geriatric mice and uncovered that as these cells age, they show signs of increased immune activity and start to lose their ability to stay dormant, which is vital for their function. We also identified specific areas of the genome that might be responsible for these changes. By targeting these areas, we could potentially restore the function of these stem cells and help maintain muscle health as we age.

And perhaps they contributed to the redesignation of the CFB as a Center for Advanced Technology for ten years by the New York State Foundation for Science, Technology and Innovation (NYSTAR) as a Center for Advanced Technology (CAT). The New York State redesignation recognizes the impact of the CFB over 30 years driving innovation toward commercial goals and resulting in accelerated product development cycles "from bench to boardroom to bedside." It recognizes the key role played by the CFB in facilitating a regional bioscience innovation ecosystem, collaborating with Stony Brook University, Cold Spring Harbor Laboratory, and Brookhaven National Laboratory. The redesignation by New York State validates all of the work we have done over the last 10-year period to create the foundation for exponential growth. We would not have secured the National Institutes of Health REACH award without it, says Clint Rubin, Director of the Center for Biotechnology."The REACH designation represents an $8.1M investment in technology development, commercialization, and new company formation. Visionary's like New York State Senator Kenneth La Valle deserve the credit. They recognized thirty years ago that universities represented a largely untapped pool of innovation and economic potential. Strikingly, it validates and provides the foundation for the new Long Island Bioscience Hub (LIBH), a CFB-led initiative to formally bring these institutions together to foster technology development, commercialization, and new company formation. The LIBH is a bold step made possible by a partnership with the National Institute of Health REACH initiative (Research Evaluation and Commercialization Hub). The NIH award places the CFB in the national spotlight along with other elite institutions. (Read more on the NIH REACH award here) "This redesignation occurs in an interesting and changing environment, where varying elements in the regional, state, and national biotech ecosystem are aligning. There is a confluence of events and issues that are creating a unique opportunity to build the biotech economy in the region and across the State." Commented Diane Fabel, Director of Operations, CFB. "We have learned a lot about the process of moving academic innovation into the commercial sector over time. And there have been such tremendous scientific advances recently that represent new commercial opportunities and life saving technologies. There is still much to learn and do, and it is an incredibly exciting time to be doing it.     [post_title] => Center for Biotechnology Redesignated by New York State: 'Unique Time of Change and Growth' [post_excerpt] => The New York State redesignation recognizes the impact of the CFB over 30 years driving innovation toward commercial goals and resulting in accelerated product development cycles from bench to boardroom to bedside.
