Scientists discover molecule that kills pancreatic cancer cells
A research team led by scientists at Roswell Park Comprehensive Cancer Center has discovered a molecule that inhibits the growth and metastasis of pancreatic cancer cells through the iron metabolism pathway. Their findings, recently published in Molecular Cancer Therapeutics, pave the way toward the development of a new drug candidate for the treatment of pancreatic cancer.
The molecule, MMRi62, targets iron metabolism to kill cancer cells and the harmful proteins that encourage their growth and spread, suggesting that further development and refinement of this compound could lead to a new type of pancreatic cancer therapy.
“MMRi62 causes degradation of an iron-storage protein called FTH1, as well as a protein that is mutated in PDAC, resulting [in] inhibition of metastasis and ferroptosis, a form of cell death triggered by free cellular iron,” says Xinjiang Wang, Ph.D., Associate Professor in the Department of Pharmacology and Therapeutics at Roswell Park.
Tesla factory in Germany gains conditional approval to start commercial production
Tesla has gained approval to begin commercial production at its new factory near Berlin, local German officials announced Friday.
The conditional license for the vehicle and battery plants in Brandenburg was expected following months of delays. Tesla had intended to start production of vehicles by early summer of 2021 in Brandenburg, but the Covid pandemic, supply chain complications and clashes with environmentalists all slowed their pace.
The project, which was approved with the 536-page decision, includes the plant for the production of up to 500,000 vehicles per year, according to a translated release.
AgeX Therapeutics: Targeting Biological Ageing | Dr Michael D. West
Have not heard from Dr West in awhile. Two things stood out in this technical hour: Telomerase in gene therapy has never been properly developed, and their iTR technology has not had animal trials as they wait for funding.
In this #webinar, Dr Michael West, a bioentrepreneur and CEO of AgeX Therapeutics, discussed the work of AgeX Therapeutics, their mission and plan to extend human health and longevity, and exciting new #technologies that could combat #ageing and unlock cellular immortality.

Targeting the cell cycle could overcome cancer treatment resistance
Scientists from Roswell Park Comprehensive Cancer Center have shed light on a different way of overcoming mechanisms of resistance to specific therapeutic agents used to treat cancer. In a new article published March 1 in the journal Cell Reports, the researchers propose a new approach to cancer treatment based on the way different cancer cells divide.
A collaborative team led by Agnieszka Witkiewicz, MD, Professor of Oncology, and Erik Knudsen, Ph.D., Professor of Oncology and Chair of Molecular and Cellular Biology, from Roswell Park investigated over 500 cell lines from a multitude of cancer types, as well as preclinical tumor models. The researchers then analyzed cancer cells based on their dependency for CDK and CCN, two genes that drive the cell cycle and determine how often a cancer cell divides.
“We found that the way cancer cells divide is highly varied, and that diversity represents a tremendous challenge for some widely used cancer therapies because it often contributes to treatment resistance,” says Dr. Witkiewicz, the study’s senior author. “However, with a better understanding of these heterogenous features of cancer cell division, different therapies could be deployed in a more precise and effective fashion.”
Comparative analysis of genome code complexity and manufacturability with engineering benchmarks
When knowledge has advanced to a state that includes a predictive understanding of the relationship between genome sequence and organism phenotype it will be possible for future engineers to design and produce synthetic organisms. However, the possibility of synthetic biology does not necessarily guarantee its feasibility, in much the same way that the possibility of a brute force attack fails to ensure the timely breaking of robust encryption. The size and range of natural genomes, from a few million base pairs for bacteria to over 100 billion base pairs for some plants, suggests it is necessary to evaluate the practical limits of designing genomes of similar complexity.
Bill Andrews deep research to cure aging explained in 19 minutes (con S/T en Español)
In this video Bill Andrews summarizes in 19 minutes his extensive research on telomeres, aging, and his proposal to cure aging. Bill Andrews is an American molecular biologist and gerontologist, founder and CEO of the biotech company Sierra Sciences.
Bill Andrews summarizes in 19 minutes his extensive and prolific research on telomeres, aging, and the cure for aging.
The video, originally released by Bill Andrews in february 2022, among other things, covers in little less than 20 minutes the following:
1) Enlightening info about telomere shortening and its impact on aging.
2) Practical proposals to cure aging based on two different approaches to stop telomere shortening and actually enlarge them.
New Brain Map Charts Every Component in the Biological Universe
It’s easy to see why: as shockingly powerful mini-processors, neurons and their connections—together dubbed the connectome—hold the secret to highly efficient and flexible computation. Nestled inside the brain’s wiring diagrams are the keys to consciousness, memories, and emotion. To connectomics, mapping the brain isn’t just an academic exercise to better understand ourselves—it could lead to more efficient AI that thinks like us.
But often ignored are the brain’s supporting characters: astrocytes—brain cells shaped like stars—and microglia, specialized immune cells. Previously considered “wallflowers,” these cells nurture neurons and fine-tune their connections, ultimately shaping the connectome. Without this long-forgotten half, the brain wouldn’t be the computing wizard we strive to imitate with machines.
In a stunning new brain map published in Cell, these cells are finally having their time in the spotlight. Led by Dr. H. Sebastian Seung at Princeton University, the original prophet of the connectome, the map captures a tiny chunk of the mouse’s visual cortex, less than 1,000 times smaller than a pea. Yet jam-packed inside the map aren’t just neurons; in a technical tour de force, the team mapped all brain cells, their connections, blood vessels, and even the compartments inside cells that house DNA and produce energy.
