G-protein-coupled receptor ADGRG1 drives a protective microglial state in Alzheimer's disease through MYC activation Microglial ADGRG1 drives a protective state in Alzheimer’s disease by activating the transcription factor MYC, which upregulates genes associated with homeostasis, phagocytosis, and lysosomal function...

Interesting work from Xianhua Piao, MD, PhD on the interplay between G-protein-coupled receptor, ADGRG1, and MYC activation to promote a protective microglial state in a 5xFAD mouse model. Manuscript here: bit.ly/3HhtmbP

Neutrophil TLR2 signaling promotes lipid accumulation and vascular plaque growth Neutrophils are short-lived cells that are produced by the billions every day to circulate throughout the body and surveil all tissues. They are a key component of the innate immune system that play e...

Anudari Letian and the Goldberg Lab investigated how #neutrophils acquire #lipids from their environment and how this influences their functionality. Neutrophil-deficient mice showed protection against #atherosclerosis. Check on the article on bioRxiv here: bit.ly/3H9E3x5

PCSK9 drives sterol-dependent metastatic organ choice in pancreatic cancer - Nature PCSK9 regulates low density lipoprotein-cholesterol import and determines organ preference of metastatic pancreatic ductal adenocarcinoma, with PCSK9-low cells metastasizing to the liver and PCSK9-hig...

Intriguing work by @rushika-perera.bsky.social identifies #PCSK9 as a driver of metastatic growth in #pancreatic ductal adenocarcinoma. Published in @nature.com. #SciSky go.nature.com/4ksf5Y1

Cellular profiling identifies an early profibrotic alveolar type 2 cell signature in lung fibrosis Rationale Idiopathic pulmonary fibrosis (IPF) is a progressive, age-associated, lung disease characterized by short telomeres in alveolar type 2 (AT2) cells, epithelial remodeling, and fibrosis. Obje...

A collaboration between Mallar Bhattacharya and Paul Wolters shows that in a mouse model of IPF, early AT2 cell transdifferentiation and senescence is driven by enhanced p53 activity in response to #DNA damage. Out now on @biorxivpreprint.bsky.social: bit.ly/4dJG6DN #GeroSky #SciSky

Massively parallel jumping assay decodes Alu retrotransposition activity - Nature Communications Here, the authors develop a high-throughput assay to measure the jumping potential of thousands of transposons in parallel.

@nadavahituv.bsky.social and colleagues use a massively parallel jumping assay to assess the ability of retrotransposons to jump and identify nucleotide changes that have the potential to reactivate them in their latest manuscript published in @natcomms.nature.com. go.nature.com/4k7pqIK

Frailty in lung transplant recipients is associated with anemia and telomere dysfunction but independent of epigenetic age Frailty is a syndrome of vulnerability to stressors linked to worse outcomes pre- and post-lung transplantation. However, the biological basis of this…

Frailty in lung transplant patients is linked to anemia and telomere dysfunction. A study by John Greenland found that epigenetic aging correlated with chronological age, and not with frailty, highlighting the importance of telomere dysfunction and anemia in this patient population. bit.ly/4mvBgyi

Our morning concluded with a few more trainee talks and another keynote speaker, Dr. Beth Stevens. #microglial #CNS #inflammation #aging

Keynote speaker Dr. Vera Gorbunova kicked off the symposium followed by two of our trainees Mariko Foecke and Christoforos Meliadis. #ovary #bone #aging

Today is a special day! It's our second BARI symposium at the de Young Museum in the beautiful Golden Gate Park.

Aging activates escape of the silent X chromosome in the female mouse hippocampus Aging activates the silent X chromosome, increasing escape expression, and potentially cognitive resilience, in the female mouse.

Could a reawakening of the silenced X chromosome in females help slow aging-induced cognitive decline? Check out the work by @denadubal.bsky.social along with colleagues Kaitlin Casaletto, Bérénice Benayoun, and Vijay Ramani in Science Advances: bit.ly/3FlN3hj #GeroSky #SciSky

HypoxyStat, a small-molecule form of hypoxia therapy that increases oxygen-hemoglobin affinity A small molecule that increases oxygen-hemoglobin affinity was shown to prevent and reverse pathology in a mouse model of mitochondrial disease, thereby enabling a practical form of hypoxia therapy.

Research from Isha Jain and colleagues published in @cellpress.bsky.social shows that HypoxyStat can prevent or reverse mitochondrial disease in a preclinical mouse model. The study suggests potential transformations in therapeutic strategy for treating other mitochondrial disorders. bit.ly/4kh0csc

The maternal X chromosome affects cognition and brain ageing in female mice - Nature The maternal X chromosome in female mice impairs cognition through the silencing of certain genes and accelerates ageing of the hippocampus.

👏 Don't miss Samira Abdulai-Saiku's manuscript published in @nature.com! Great work coming from @denadubal.bsky.social's lab, furthering our understanding of the relationship between the X chromosome and brain aging. www.nature.com/articles/s41...

Epidermal Penetration Increases with Age and May Contribute to Systemic Inflammation The skin is a major contributor to the age-associated rise in systemic inflammation, known as
