Bladder small-cell carcinoma can be divided into different subtypes depending on the expression of neuroendocrine (NE) markers such as POU2F3, NEUROD1 and ASCL1. Single-cell RNA sequencing previously found a distinct subpopulation with high expression of 1-phosphatidylinositol 4,5-bisphosphate phosphodiesterase gamma-2 (PLCG2) with pro-metastatic features and poor prognosis. The aim of a newer study was to evaluate the expression of PLCG2 in bladder NE tumors and correlate it with prognostic utility.
Researchers from the University of Pittsburgh Medical Center and affiliated organizations aimed to validate a novel marker of duodenal neuroendocrine tumors (DNETs), NKK6.2.
Researchers from Case Western Reserve University presented data from a study that aimed to investigate gut integrity, oxidized lipids and inflammatory markers associated with the pathogenesis of post-acute sequelae of COVID-19 (PASC).
The mechanisms behind the mortality associated with early antiretroviral therapy (ART) treatment in children infected perinatally with HIV are poorly understood. Researchers sought to find potential biomarkers associated with the increased mortality. They created three groups of subjects: deceased (dead HIV+, n=20), nondeceased HIV+ (HIV+, n=59) and healthy controls (n=13).
Researchers from IrsiCaixa Institute for AIDS Research presented data from a study that aimed to identify biomarkers associated with virus control during monitored antiretroviral pause (MAP) in patients with HIV.
To date, there is a lack of consensus in anal cancer screening. DNA methylation markers zing finger protein 582 (ZNF582) and achaete-scute homolog 1 (ASCL1) have been associated with anal intraepithelial neoplasia (AIN3) and anal carcinoma risk in people with HIV infection.
Since episodes of idiopathic anaphylaxis (IA) are often accompanied by gastrointestinal (GI) manifestations, researchers from the National Institutes of Health aimed to investigate whether surrogate markers of GI permeability are aberrant in patients with IA.
Primary sclerosing cholangitis (PSC) is a rare chronic and progressive autoimmune bile duct disease that is strongly associated with several immune-mediated disorders, the shared etiology and underlying characteristics of which is not completely understood. Researchers from Baylor College of Medicine investigated the shared genetic architecture of PSC with a variety of clinical and epidemiological traits and aimed to identify new lead PSC risk-associated loci.
