Kate O'Donnell @kateodonnell-lab.bsky.social · 26/06/2026Congratulations Trudy, Luke, & team! This is fascinating new biology and a fun collaboration! This work provides new insight into the lineage plasticity underlying intratumoral heterogeneity that may lead to new therapeutic strategies in LUSC. 020

With the An & Zhang labs at @uthealthhouston.bsky.social, we show that monoclonal antibodies targeting PCDH7 inhibit tumor growth and enhance immune responses in multiple KRAS-mutant lung cancer models. www.science.org/doi/10.1126/...science.orgMonoclonal antibodies targeting PCDH7 inhibit tumor growth and enhance immune responses in KRAS-mutant non–small cell lung cancerAntibody targeting of PCDH7 inhibits tumor growth, enhances KRAS-targeted therapy response, and directs tumor immunosurveillance. 140

Reposted by Kate O'DonnellTrudy G. Oliver @tgoliver.bsky.social · 12/11/2025Congrats to Kate and Hari for a very nice story and wonderful collaboration! TMPRSS11B is a target of KLF4 and part of a chemo-refractory hillock-like state we see in squamous lung cancer. This gene contributes to acidified TME. More coming on the hillock state after addressing FIVE reviewers! 👇🏼 061
Kate O'Donnell @kateodonnell-lab.bsky.social · 11/11/2025I am pleased to present a new paper from my lab led by Hari Shankar Sunil showing that the transmembrane serine protease TMPRSS11B promotes an acidified tumor microenvironment and immune suppression in squamous lung cancer, OUT NOW in EMBO Reports👇: embopress.org/doi/full/10.... 1101
