Detection and quantitation of ferritinophagy using halo-tag tracing Iron is an essential element required for critical processes such as oxygen transport, energy generation, and DNA synthesis. To be incorporated as a cofactor, iron that is stored in the cytosol within...

I am very happy to share our recently published work in JBC @asbmb.bsky.social. We generated a tool to detect and quantitate ferritinophagy. We hope that this tool will be useful in iron biology research.

My quote of the day

As I reflect on my life, I recognize that our greatest achievements often arise from our most profound struggles. Embrace challenges and view failures as opportunities for growth. It is through these trials that we learn, adapt, and ultimately succeed.

Cancer centers adapt to life without site visits as NIH changes CCSG review - The Cancer Letter Love them or hate them, site visits have been a part of the culture of NCI-designated cancer centers for decades, shaping the process for admitting members to the elite club and influencing internal politics within institutions.

Robert Winn (@aacicancer.bsky.social): “Having Tony [Letai] come in now as the actual NCI director gives us an opportunity to keep the process potentially within @theNCI, which is what I’m going to advocate for—and that we narrow the site visits."

Accumulation of succinate suppresses de novo purine synthesis through succinylation-mediated control of the mitochondrial folate cycle The de novo purine synthesis pathway is fundamental for nucleotide production, yet the role of mitochondrial metabolism in modulating this process rem…

Excited to share our latest work out today in @cp-molcell.bsky.social, revealing a molecular link between succinate dehydrogenase and purine synthesis, connecting two fundamental metabolic pathways. Huge congratulations to the first author, Mushtaq Nengroo! www.sciencedirect.com/science/arti...

FSP1-mediated lipid droplet quality control prevents neutral lipid peroxidation and ferroptosis - Nature Cell Biology Lange et al. identify a lipid droplet quality control pathway in which FSP1 safeguards stored neutral lipids from lipid peroxidation, thereby preventing the induction of ferroptosis.

Excited to share my postdoc work @olzmannlab.bsky.social! We found lipid droplets, the cell’s lipid storage depots, are subject to oxidative damage and are protected by FSP1. Loss of FSP1 triggers droplet peroxidation and cell death, revealing a new layer of lipid quality control!

VPS13C/PARK23 initiates lipid transfer and membrane remodeling for efficient lysosomal repair Perturbations in lysosome integrity are tightly linked to neurological disorders and ageing, but the underlying pathogenic mechanisms are incompletely understood. Using an unbiased proteomic approach,...

Proud to share a preprint of our paper on how bridge-like lipid transport protein VPS13C senses lysosomal membrane tension in anticipation of membrane lesions to initiate net ER-to-lysosome lipid transfer for efficient lysosomal repair www.biorxiv.org/content/10.1...

Many thanks to all the trainees in our laboratory for their dedication and hard work. I represent their success.

Secretary Kennedy Swears in Dr. Anthony Letai as Director of the National Cancer Institute Dr. Letai will serve as NCI’s 18th director.

We want to congratulate our President, Dr. Tony Letai, on his appointment as Director of the NCI. This announcement marks an historic moment for cancer research. Dr. Letai has been a tireless advocate and visionary leader for functional precision medicine 🧵

A huge shoutout to all the dedicated grants management specialists at the NIH who are working around the clock to push grants out before the Sep 30 deadline. And also to the POs responding to frantic emails.
Not an easy job under the best of circumstances and right now it's the pits.
Thank you!

Quantitative imaging of lipid transport in mammalian cells - Nature Directional, non-vesicular lipid transport is responsible for fast, species-selective lipid sorting into organelle membranes.

The goal of a PhD is not to learn some facts or read a few papers or learn a bunch of techniques. The goal of a PhD is to learn independence, problem solving, how to finish things you start, resilience, & gain the ability to adapt & think creatively. Learning these things is hard.

Ray Blind (@blindlab.bsky.social), an associate professor at Vanderbilt University Medical Center & @vumedicine.bsky.social, investigates how ligands bind & change the activity of two nuclear receptor 5A, or NR5A, family members called steroidogenic factor-1 & liver receptor homomlog-1, or LRH-1.

The source of dietary fat influences anti-tumour immunity in obese mice - Nature Metabolism This study shows that animal-based high-fat diets accelerate tumour growth and impair anti-tumour response to melanoma in obese mice, whereas plant-based high-fat diets do not.

This was a labor of love requiring lots of teamwork over years, repeating in 3 locations! Thanks to all the lab over the years, giving their time generously to this team project, & our wonderful collaborators. The source of fat matters for anti-tumor immunity 🐄🐖🧈🌴🫒🥥
