Abstract The increased treatment of metastatic castration-resistant prostate cancer (mCRPC) with second-generation antiandrogen therapies (ADT) has coincided a greater incidence lethal, aggressive variant (AVPC) tumors that have lost dependence on androgen receptor (AR) signaling. These AR-independent may also transdifferentiate to express neuroendocrine lineage markers and are termed (NEPC). Recent evidence suggests kinase signaling be an important driver NEPC. To identify targetable...
Castration-resistant prostate cancer (CRPC) consists of multiple phenotypic subtypes including androgen receptor (AR)-active (ARPC) and neuroendocrine (NEPC). Tumor cells with these phenotypes can coexist between metastases within a patient an individual tumor. Treatments that are effective across CRPC currently lacking. Histone deacetylation is crucial for the regulation chromatin structure maintenance cell state activation PI3K/AKT/mTOR signaling cascade tumor growth-promoting pathway. We...
Introduction Brain tumors are the most common solid malignancy and leading cause of cancer-related deaths in infants. Current epidemiological data is limited by low numbers reported cases. This study used a population-based approach with analysis contemporary historical survival curves to provide up-to-date prognostication. Methods Observational cohort was performed using Surveillance, Epidemiology End Results (SEER) database. Infants brain diagnosed from 1973 2013 were categorized tumor...
Abstract Increased treatment of metastatic castration resistant prostate cancer (mCRPC) with second-generation anti-androgen therapies (ADT) has coincided a greater incidence lethal, aggressive variant (AVPC) tumors that have lost androgen receptor (AR) signaling. AVPC may also express neuroendocrine markers, termed (NEPC). Recent evidence suggests kinase signaling be an important driver NEPC. To identify targetable kinases in NEPC, we performed global phosphoproteomics comparing AR-negative...
