🚀 New preprint! Meet ORIGAMI: Mapping cancer cell state heterogeneity and plasticity, predicting and steering therapy-induced trajectories to rationalize genotype-agnostic combination strategies with only two physical metrics (cell surface area and volume) www.researchsquare.com/article/rs-8...

Simple cell geometry metrics reveal cancer cell diversity and plasticity and guide combination therapy
Intra-tumour heterogeneity (ITH) and cellular plasticity contribute to therapy resistance. Single-cell transcriptomics is the gold standard for assessing ITH, but this approach remains costly and slow...

CDH3-AS1 antisense RNA enhances P-cadherin translation and acts as a tumor suppressor in melanoma
Chadourne et al. identify CDH3-AS1 as a downregulated antisense RNA in melanoma that enhances P-cadherin translation through a SINEUP-like mechanism. CDH3-AS1 overexpression suppresses melanoma growth...

Just like there are good and bad macrophages..., there are good and bad NK cells!! This has profound therapeutic implications, far beyond oncology! Thanks to CD for highlighting both papers and the superb and efficient editorial work! Thanks to our collaborators (especially Zihai Li) and funders!

My recent postdoctoral work is out today in @nature.com! We found that physical confinement makes melanoma cells more invasive and drug tolerant. Thanks to all who made this work possible @whitefishlab.bsky.social @mskcancercenter.bsky.social #NIH #NCI www.nature.com/articles/s41...

With the NCI payline lowered to 4th percentile, this unfortunately did not age well

Another preprint from our group. Here we show that FRA1 is a potent driver of #melanoma metastasis and inhibiting some of FRA1's transcriptional targets diminishes dissemination
