It's that time of the year when students apply to Professors for MSc, PhD or PDF mentorship. Great! Tip: Please remember to state in your email, where you received your undergraduate or graduate degrees, country & year. Be unique. Stand out.

LKB1 (STK11) @stk11.bsky.social · 22/06/2026
LKB1 loss suppresses estrogen, progesterone, and androgen signalling pathways, and that HLA-DRB5 is consistently downregulated across all STK11-mutated subtypes, suggesting an immune evasion component. A lot going on beyond the canonical AMPK-mTOR axis.

Preprint from marignanilab.com. LKB1 isn't just a tumour suppressor kinase with metabolic function; there's more😁. We used scRNAseq, CRISPR, patient tumours, METABRIC genomics & new mouse model to ask:what is the impact of losing LKB1 expression on breast cancer? www.biorxiv.org/content/10.6...
