Using lineage tracing, limiting dilution assays, and in vivo live imaging approaches, scientists identified a rare inhibitory receptor programmed cell death 1 (PD-1)-expressing cells that resided at the apex of leukemia hierarchy for initiation and relapse in T cell acute lymphoblastic laukemia.

To investigate the CSC properties of pancreatic cancer cells, the authors used a pancreatic CSC model, degron (++) cells, which have low proteasome activity. Degron (++) cells displayed radioresistance in comparison with control cells.

Results using hepatocellular carcinoma patient samples showed a positive correlation between indoleamine 2,3-dioxygenase-1, a kynurenine producing enzyme with effects on tumor immune escape, and Lin28B.

Scientists demonstrated that RAC1B, the only known alternatively spliced variant of the small GTPase RAC1, was expressed in a subset of breast CSCs (BCSCs) in vivo and its function was required for the maintenance of BCSCs and their chemoresistance to doxorubicin.

High expression of ATP Binding Cassette subfamily C member 3 (ABCC3) was restricted to glioblastoma, with negligible levels in healthy brain tissue, and further correlated with tumor grade and stemness markers.

The degree of stromal tumor-infiltrating lymphocytes was evaluated using hematoxylin and eosin-stained slides. Immunohistochemical analysis of B7-H4, CSC-related biomarkers, and epithelial-mesenchymal-transition-related biomarkers was performed using tissue microarray. [Journal Of Ovarian Research]

CSCs have obvious radio-resistance compared with non-CSCs, and charged particle irradiation or in combination with drugs could overcome this resistance, specifically manifested in inhibiting CSCs’ proliferation, invasion, migration, and causing more DNA double-stranded breaks (DSB) of CSCs.

The initial Phase I clinical trial will assess safety and therapeutic benefit from the administration of Phio’s PH-762 treated “double positive” CD8 tumor infiltrating lymphocyte in patients with melanoma and other advanced solid tumors. [Phio Pharmaceuticals Corp.]
