Effect of Cariprazine on Outcomes in Older-aged and Younger-aged Patients with Bipolar I Disorder: A Post-hoc Analysis.

Objectives: To evaluate cariprazine in adults with older- and younger-age bipolar I disorder (OABD-I and YABD-I) and compare treatment effects between them.

Design And Setting: Pooled post-hoc analysis of studies in depressive or acute manic/mixed episodes associated with bipolar I disorder.

Participants: 475/1383 patients (34.

IDO Downregulation Induces Sensitivity to Pemetrexed, Gemcitabine, FK866, and Methoxyamine in Human Cancer Cells.

Indoleamine 2,3-dioxygenase-1 (IDO) is an immune regulatory enzyme expressed by most human tumors. IDO levels in tumor cells correlate with increased metastasis and poor patient outcome and IDO is linked to tumor cell resistance to immunotherapy, radiation therapy, and chemotherapy. Knowledge of tumor cell-autonomous effects of IDO, independent of its well-known role in regulating and suppressing anti-tumor immune responses, is limited.

siRNA knockdown of mitochondrial thymidine kinase 2 (TK2) sensitizes human tumor cells to gemcitabine.

Nucleoside metabolism enzymes are determinants of chemotherapeutic drug activity. The nucleoside salvage enzyme deoxycytidine kinase (dCK) activates gemcitabine (2', 2'-difluoro-2'-deoxycytidine) and is negatively regulated by deoxycytidine triphosphate (dCTP). Reduction of dCTP in tumor cells could, therefore, enhance gemcitabine activity.

BRCA2 inhibition enhances cisplatin-mediated alterations in tumor cell proliferation, metabolism, and metastasis.

Tumor cells have unstable genomes relative to non-tumor cells. Decreased DNA integrity resulting from tumor cell instability is important in generating favorable therapeutic indices, and intact DNA repair mediates resistance to therapy. Targeting DNA repair to promote the action of anti-cancer agents is therefore an attractive therapeutic strategy.

Regional localization within the bone marrow influences the functional capacity of human HSCs.

Numerous studies have shown that the bone marrow (BM) niche plays a key role in mouse hematopoietic stem cell (HSC) function and involves contributions from a broad array of cell types. However, the composition and role of the human BM HSC niche have not been investigated. Here, using human bone biopsy specimens, we provide evidence of HSC propensity to localize to endosteal regions of the trabecular bone area (TBA).
