Beta-Cryptoxanthin (beta Cx) was investigated for cell functions in neuroblastoma Neuro2a cells. The following results were obtained. 1. Beta-Cx induced neurite outgrowth. 2. Beta-Cx inhibited the etoposide-induced activation of caspase-3 activity in a dose-dependent manner. These data suggest a bioregulatry function of beta Cx in the control of differentiation and apoptosis in Neuro2a cells.

Deciphering the complex clonal heterogeneity of polycythemia vera and the response to interferon alpha.

Interferon alpha (IFNa) is approved for the therapy of patients (pts) with polycythemia vera (PV), a subtype of myeloproliferative neoplasms (MPN). Some pts achieve molecular responses (MR), but clonal factors sensitizing for MR remain elusive. We integrated colony formation and differentiation assays with single-cell RNA seq and genotyping in PV-derived cells vs.

The global prevalence of heart failure is still growing, which imposes a heavy economic burden. The role of microRNA-146b (miR-146b) in HF remain largely unknown. This study aims to explore the role and mechanism of miR-146b in HF.

Anti-Müllerian hormone (AMH) protects the ovarian reserve from chemotherapy, and this effect is most pronounced with Doxorubicin (DOX). However, DOX toxicity and AMH rescue mechanisms in the ovary have remained unclear. Herein, we characterize the consequences of these treatments in ovarian cell types using scRNAseq.

Objective: To study the subcutaneous adipose tissue (SAT) transcriptome in people with HIV (PWH) switching efavirenz (EFV) or a protease inhibitor (PI) to raltegravir and to compare the transcriptome of PWH to those of people without HIV (PWoH).
Design: PWH (n = 36) on EFV (n = 22) or a PI (n = 14) based ART regimen were randomized to switch to RAL (n = 15) or to continue unchanged medication (n = 17). PWoH (n = 10), comparable in age and body mass index, were included for comparison.

The secretome is composed of cell surface membrane proteins and extracellular secreted proteins that are synthesized via secretory machinery, accounting for approximately one-third of human protein-encoding genes and playing central roles in cellular communication with the external environment. Secretome protein-protein interactions (SPPIs) mediate cell proliferation, apoptosis, and differentiation, as well as stimulus- or cell-specific responses that regulate a diverse range of biological processes. Aberrant SPPIs are associated with diseases including cancer, immune disorders, and illness caused by infectious pathogens.
