A Popular Science View of the Road to Partial Reprogramming Therapies
Reprogramming via expression of the Yamanaka factors slowly transforms somatic cells from tissues of any age into induced pluripotent stem cells that are essentially identical to embryonic stem cells. Along the way, aged epigenetic patterns are reset to a youthful configuration, and age-related decline of mitochondrial function is reversed. This approach recapitulates the cellular rejuvenation that takes place in early embryonic development.
Interestingly, temporarily exposing old animals to Yamanaka factors produces improved health and far less cancer than one might expect. It appears that it may be possible to bui...

Towards Clinical Trials for ISRIB
ISRIB has for some years been under investigation as a way to reduce the impact of neurodegeneration and improve cognitive function. It is one of a number of small molecule approaches to upregulate forms of cellular housekeeping, the unfolded protein response in this case. More cellular maintenance in principle means a lower burden of molecular damage and cellular dysfunction at any given time. Since most of these maintenance processes appear to decline in efficacy with age, improvement is a compensatory strategy that might help. In many cases exercise produces more impressive effects than the present state of the art in p...

In conclusion, the effects of MR on the gut barrier were likely related to alleviation of the oscillations of inflammation-related microbes. MR can enable nutritional intervention against age-related gut barrier dysfunction.

In conclusion, senolytic drugs have shown promising results in the elimination of senescent cells and in alleviating various diseases in animal models. However, in patients, there is a paucity in data on the efficacy and safety of senotherapeutics from clinical trials, including systemic effects and side-effects. In this regard it is important to assess the specificity of senolytics in killing targeted senescent cells and their cytotoxic effects, to identify reliable markers for intervention responses, to elucidate interactions with comorbidities and other drugs, and to standardise administration protocols.

Request for Startups in the Rejuvenation Biotechnology Space, 2022 Edition
For some years now, I've offered a yearly set of suggested projects for new startups in the rejuvenation biotechnology space. Or, alternatively, it might be viewed as a series of lengthy complaints about the slow pace of process towards human rejuvenation, given the many opportunities that exist. That slow pace is particularly galling in the case of the lowest-hanging fruit, a range of therapies that have been practical to carry out for at least a few years now, and yet have still not been meaningfully assessed for their ability to produce at least some degree of rejuvenation in aged humans. Given that the level of funding...
