Story Circles of Black Doulas, Cultural Brokers for Birthing People in Healthcare.

Doula care services (in-person, hybrid, and virtual) during the COVID-19 pandemic may vary. The purpose of this study was to explore doulas' experiences as birthing professionals and epistemological resources assisting Black birthing families during the pandemic. Virtual qualitative story circles were conducted with 11 Black doulas who attended births as doulas from January 2020 to December 2021.

Polyomavirus ALTOs, but not MTs, downregulate viral early gene expression by activating the NF-κB pathway.

Polyomaviruses are small, circular dsDNA viruses that can cause cancer. Alternative splicing of polyomavirus early transcripts generates large and small tumor antigens (LT, ST) that play essential roles in viral replication and tumorigenesis. Some polyomaviruses also express middle tumor antigens (MTs) or alternate LT open reading frames (ALTOs), which are evolutionarily related but have distinct gene structures.

Merkel cell polyomavirus protein ALTO modulates TBK1 activity to support persistent infection.

While Merkel cell polyomavirus (MCPyV or MCV) is an abundant virus frequently shed from healthy skin, it is one of the most lethal tumor viruses in immunocompromised individuals, highlighting the crucial role of host immunity in controlling MCPyV oncogenic potential. Despite its prevalence, very little is known about how MCPyV interfaces with the host immune response to maintain asymptomatic persistent infection and how inadequate control of MCPyV infection triggers MCC tumorigenesis. In this study, we discovered that the MCPyV protein, known as the Alternative Large Tumor Open Reading Frame (ALTO), also referred to as middle T, effectively primes and activates the STING signaling pathway.

MicroRNAs as Bile-based biomarkers in pancreaticobiliary cancers (MIRABILE): a cohort study.

Background: Biliary obstruction can be due to both malignant and benign pancreaticobiliary disease. Currently, there are no biomarkers that can accurately help make this distinction. MicroRNAs (miRNAs) are stable molecules in tissue and biofluids that are commonly deregulated in cancer.
