Researchers Slow Aging in Cells

Posted by in categories: biotech/medical, genetics, life extension

Scientists are still determining whether humans will reach a maximum possible age or if we can extend lifespan indefinitely. One thing we know is that the aging we see and feel in our bodies is connected to aging that individual cells experience. Yeast is a common model in molecular biology that is often used to study aging. In 2020, scientists found that yeast cells could go down one of two aging paths; in one, structures called nucleoli were degraded and ribosomal DNA experienced less silencing; in the other, mitochondria were affected and heme accumulation was reduced. The researchers suggested that these were two distinct types of terminal aging.

In follow-up work, the research team has manipulated the genetics of those pathways, and have extended the lifespan of cells by doing so. The work has been reported in Science. The investigators applied a solution to the cells that altered gene circuits to stop the cells from deteriorating.

The impact of technology on drug discovery

Posted by in category: biotech/medical

This is the latest episode of the free DDW narrated podcast, “The impact of technology on drug discovery”. It covers two articles written for Volume 23, Issue 2 – Spring 2022 of DDW. They are called “Talking Tech” and “Rejuvenation biotech: Can this company make age a thing of the past?

With Covid-19 taking so much of the drug discovery and development’s focus over the last two years, it has been easy to overlook other areas within the sector that deserve our attention. So in the first article, Lu Rahman highlights the technology that will play a valuable role in the industry.

Kizoo Technology Capital has a clear aim – to develop drugs that abate or cure age-related diseases. In the second article, Lu Rahman spoke to owner, Michael Greve, to find out more about this exciting work that aims to make age-related therapies affordable for everyone.

Pfizer, Astellas Pharma‘ Xtandi combo therapy cuts risk of metastasis, death by 58 percent in prostate cancer

Posted by in categories: biotech/medical, law

“There are patients with localized prostate cancer who undergo prostatectomy or radiation therapy in an attempt to cure their disease, but, unfortunately, some patients will develop BCR,” said Neal Shore, M.D., F.A.C.S., U.S. Chief Medical Officer of Urology and Surgical Oncology, GenesisCare, Director, Carolina Urologic Research Center, and Primary Investigator for the EMBARK study. “Importantly, some patients with BCR are at very high risk for developing metastatic disease, which can lead to a cascade of therapeutic interventions. The clinical goal of BCR therapy is to delay cancer progression and avoid metastatic disease. The MFS results from the EMBARK study demonstrate that this intervention with XTANDI plus leuprolide was statistically significant for patients with high-risk BCR.”

“The EMBARK study is a Phase 3 trial exploring the potential of enzalutamide in patients with non-metastatic hormone-sensitive prostate cancer with high-risk BCR,” said Stephen J. Freedland, M.D., Director of the Center for Integrated Research in Cancer and Lifestyle and the Warschaw Robertson Law Families Chair in Prostate Cancer at Cedars-Sinai Cancer and Co-Principal Investigator of the Clinical Trial. “If approved, we hope to bring a new option to men earlier in the course of their disease.”

Consistent with the study’s primary endpoint, statistically significant and clinically meaningful improvements were also observed in the trial’s key secondary endpoints in both the XTANDI combination and monotherapy arms. Specifically, the XTANDI monotherapy arm demonstrated that treatment with XTANDI reduced the risk of metastasis or death by 37% versus leuprolide plus placebo (HR: 0.63; 95% CI, 0.46–0.87; P=0.0049), meeting its MFS endpoint. Treatment with XTANDI plus leuprolide and XTANDI monotherapy reduced the risk of PSA progression by 93% (HR: 0.07; 95% CI, 0.03–0.14; P0.0001) and 67% (HR: 0.33; 95% CI, 0.23–0.49; P0.0001), respectively, versus placebo plus leuprolide. The progression risk in starting a new antineoplastic therapy was reduced by 64% in those treated with XTANDI plus leuprolide (HR: 0.36; 95% CI, 0.26–0.49; P0.0001) and 46% in those treated with XTANDI monotherapy (HR: 0.54; 95% CI, 0.41–0.71; P0.0001) versus placebo plus leuprolide.

AI pioneer quits Google to warn about the technology’s ‘dangers’

Posted by in category: robotics/AI

Geoffrey Hinton, who has been called the ‘Godfather of AI,’ confirmed Monday that he left his role at Google last week to speak out about the “dangers” of the technology he helped to develop.

Hinton’s pioneering work on neural networks shaped artificial intelligence systems powering many of today’s products. He worked part-time at Google for a decade on the tech giant’s AI development efforts, but he has since come to have concerns about the technology and his role in advancing it.

“I console myself with the normal excuse: If I hadn’t done it, somebody else would have,” Hinton told the New York Times, which was first to report his decision.

The human brain is a complex and unfathomable supercomputer. How it works is one of the ultimate mysteries of our time. Scientists working in the exciting field of computational neuroscience seek to unravel this mystery and, in the process, help solve problems in diverse research fields, from Artificial Intelligence (AI) to psychiatry.

Computational neuroscience is a highly interdisciplinary and thriving branch of neuroscience that uses computational simulations and mathematical models to develop our understanding of the brain. Here we look at: what computational neuroscience is, how it has grown over the last thirty years, what its applications are, and where it is going.

Ageing Is Unstoppable? Not Even Close!

Posted by in categories: internet, life extension

Recently, a fake news article circulated the internet claiming that scientists had proven that stopping the ageing process was not possible. In this brief article, we explain why this claim is patently false and based entirely upon a wilful misinterpretation of scientific data.
