Establishment and Characterization of Three Human Ocular Adnexal Sebaceous Carcinoma Cell Lines

Researchers established three new cell lines to model ocular adnexal sebaceous carcinoma (SebCA) and test new therapies. SebCA is a highly problematic periorbital tumor requiring aggressive surgical treatment, and its pathobiology remains poorly understood. With consent from one male and two female patients, tumor tissue was cultured under conditional reprograming, and the cells were analyzed for growth, clonogenicity, apoptosis, and differentiation using methods including western blotting, short tandem repeat profiling, and next-generation sequencing. These newly developed cell lines provide valuable preclinical models for understanding and treating SebCA. Supported by ORIP (K01OD034451).
Alterations in Tumor Aggression Following Androgen Receptor Signaling Restoration in Canine Prostate Cancer Cell Lines
Vasilatis et al., International Journal of Molecular Sciences. 2024.

Prostate cancer (PCa) ranks second worldwide in cancer-related mortality, but only a few animal models exhibit naturally occurring PCa that recapitulates the symptoms of the disease. Neutered dogs have an increased risk of PCa and often lack androgen receptor (AR) signaling, which is involved in upregulating tumorigenesis but can also suppress aggressive cell growth. In this study, researchers sought to understand more about the role of AR signaling in canine PCa initiation and progression by restoring AR in canine PCa cell lines and treating them with dihydrotestosterone. One cell line exhibited AR-mediated tumor suppression; one cell line showed altered proliferation (but not migration or invasion); and a third cell line exhibited AR-mediated alterations in migration and invasion (but not proliferation). The study highlights the heterogeneous nature of PCa in dogs and humans but suggests that AR signaling might have therapeutic potential under certain conditions. Supported by ORIP (T32OD011147).
