Wnt ligands belong to a family of secreted glycoproteins in which binding to a range of receptors/co-receptors activates several intracellular pathways. WNT5A, a member of the Wnt family, is classified as a non-canonical Wnt whose activation triggers planar cell polarity (PCP) and Ca+2 downstream pathways. Aberrant expression of WNT5A has been shown to play both protective and harmful roles in an array of conditions, such as inflammatory disease and cancer. In the present study, using histological, immunohistochemical, and molecular methods, we investigated the expression of two isoforms of WNT5A, WNT5A-Short (WNT5A-S) and WNT5A-Long (WNT5A-L) in bladder urothelial carcinoma (UC). Three …

Triple-negative breast cancer (TNBC), the most aggressive subtype of breast cancer, has a poor prognosis and lacks effective treatment strategies. Here, the study discovered that TNBC shows a decreased expression of epithelial transcription factor ovo-like 2 (OVOL2). The loss of OVOL2 promotes fatty acid oxidation (FAO), providing additional energy and NADPH to sustain stemness characteristics, including sphere-forming capacity and tumor initiation. Mechanistically, OVOL2 not only suppressed STAT3 phosphorylation by directly inhibiting JAK transcription but also recruited histone deacetylase 1 (HDAC1) to STAT3, thereby reducing the transcriptional activation of downstream genes carnitine palmitoyltransferase1 (CPT1A and CPT1B). PyVT-Ovol2 knockout mice develop a …

The bacterium that causes syphilis, Treponema pallidum subsp. pallidum, has now been cultured in vitro continuously for periods exceeding 3 years using a system consisting of coculture with Sf1Ep rabbit epithelial cells in TpCM-2 medium and a low-oxygen environment. In addition, long-term culture of several other syphilis isolates (SS14, Mexico A, UW231B, and UW249B) and the T. pallidum subsp. endemicum Bosnia A strain has been achieved. During in vitro passage, T. pallidum subsp. pallidum exhibited a typical bacterial growth curve with logarithmic and stationary phases. Sf1Ep cells are required for sustained growth and motility; however, high initial Sf1Ep cell …
