Latest journey in #prostatecancer cell plasticity. Team effort @ChrisSweens1 @kat_morel @BeatrizGerFalc Work stems from previous @ChrisSweens1 investigations in NFkB regulation by tristetraprolin (TTP; gene ZFP36), and generation of the NFkBi dimethylaminoparthenolide (DMAPT)

Do you use Hallmark_Estrogen_Response_Early/Late signatures from MSigDB? Then try out more comprehensive signatures such as ones we generated from gene expression changes across 66 RNA-seq and 80 microarray experiments e.g. LI_ESTROGENE_META_E2_RESPONSE_UP gsea-msigdb.org/gsea/msigdb/โ€ฆ

This is such an unacceptable response for an NIH PD to give to a trainee. For the record she did read the notices and discuss with her mentor (me), and I recommended she reach out and ask. Wonder why talented young people are leaving academia? This is why @NIH ๐Ÿ˜‘

Our work on metabolism of quiescent cells! A bit of a new area for us in collaboration with the Buckanovich lab
New research reveals that #acetate drives quiescence in ovarian #cancercells by boosting ACSS2-mediated acetyl-CoA production. High ACSS2 levels are linked to poor patient outcomes and #chemoresistance. Targeting ACSS2 could enhance treatment response! ๐Ÿ”—sciencedirect.com/science/arโ€ฆ

Glad to share our study in npj Precision Oncology nature.com/articles/s41698-0โ€ฆ, where we cross-compared transcriptomes and immune infiltration in ILC tumors, building on work by @OnkarSayali (nature.com/articles/s43018-0โ€ฆ). Our findings reveal a proliferative subtype linked to increased suppressive immune infiltration, and a signature characterized by lower proliferation, pro-inflammatory TAM infiltration, and improved survival in ER breast cancer. Great appreciations to co-authors Drs. Sayali Onkar @OnkarSayali, Jian Zou, Yujia Li, Haley Arbore @haley_arbore00, Sai Maley, George Tseng, Peter C. Lucas, Tullia C. Bruno @BcellBruno, Dario A. Vignali @Vignali_Lab, Julia Foldi @JuliaFoldiMD, Marija Balic, and especially mentors Drs. @Adrianvlee & @oesterreichs for their invaluable support, expertise, and contributions. #BreastCancer #ImmunoOncology #PrecisionMedicine #CancerResearch #ERPositive #LobularCancer #Oncology
