Breast cancer remains the leading cause of mortality among women with cancer. This article delves into the intricate relationship between breast cancer and cancer stem cells (CSCs), emphasizing advanced methods for their identification and isolation. The key isolation techniques, such as the mammosphere formation assay, surface marker identification, Side Population assay, and Aldehyde Dehydrogenase assay, are critically examined.

Bladder cancer (BLCA) genomic profiling has identified molecular subtypes with distinct clinical characteristics and variable sensitivities to frontline therapy. BLCAs can be categorized into luminal or basal subtypes based on their gene expression. We comprehensively characterized nine human BLCA cell lines (UC3, UC6, UC9, UC13, UC14, T24, SCaBER, RT4V6 and RT112) into molecular subtypes using orthotopic xenograft models.

We hypothesized that these variations might be subclonally present at disease onset and contribute to relapse risk. To test this, we examined two cohorts of children diagnosed with T-ALL: one with 81 patients who relapsed and 79 matched non-relapsing controls, and another with 226 consecutive patients, 30 of whom relapsed.

Although recent evidence suggests that myeloid clonal hematopoiesis (M-CH) may influence lymphoma clinical outcome, its impact in mantle cell lymphoma (MCL) remains unclear. Here, we report a comprehensive NGS-based analysis of the M-CH mutational landscape at baseline and follow-up in patients enrolled in the Fondazione Italiana Linfomi (FIL) MCL0208 phase 3 trial (NCT02354313), evaluating lenalidomide maintenance versus observation after chemoimmunotherapy and autologous stem cell transplantation (ASCT) in untreated young MCL patients. Overall, 254/300 (85%) enrolled patients (median age 57 years [32-66]) had a baseline sample available for CH analysis.

(-)-Cryptanoside A () was identified previously as a major cytotoxic component of the stems of collected in Laos, which mediates its activity by targeting Na/K-ATPase (NKA), with hydrogen bonds formed between its 11- and 4'-hydroxy groups and NKA being observed in its docking profile. In a continuing investigation, and its 17-epimer, (-)-17--cryptanoside A (), and the new (+)-2-hydroxyandrosta-4,6-diene-3-one-17-carboxylic acid () and the known (+)-2,21-dihydroxypregna-4,6-diene-3,20-dione or 2-hydroxy-6,7-didehydrocortexone () pregnane-type steroids were isolated from . In addition, (-)-11,4'-di--acetylcryptanoside A () has been synthesized from the acetylation of .
