Background: Evidence increasingly indicates that HPV infection plays a pivotal role in the initiation and progression of bladder cancer (BC). Yet, determining the predictive value of HPV-associated genes in BC remains challenging. Methods: We identified differentially expressed HPV-associated genes of BC patients from the TCGA and GEO databases. ⋯ Risk scores were correlated with tumor microenvironment (TME) scores, immune cell infiltration, and sensitivities to both chemotherapy and immunotherapy. Conclusion: We have formulated a risk-assessment model pinpointing 13 central HPV-associated genes in BC. These genes present potential as prognostic indicators and therapeutic targets, emphasizing the intertwined relationship between HPV-induced BC progression and the immune landscape.

Purpose: Pancreatic cancer has the worst prognosis of all common cancers worldwide. Cadherin plays important roles in cancer cell invasion and metastasis. This study investigated the role and mechanism of Cadherin 23 (CDH23) action in the viability of pancreatic cancer cells. ⋯ The viability and migration of pancreatic cancer cells in monolayer culture conditions did not change when CDH23 was silenced. The level of phosphorylated AKT was significantly decreased in the CDH23 knockdown cells in floating culture conditions. Conclusion: High levels of CDH23 expression are correlated with a poor prognosis in pancreatic cancer and may serve as a novel prognostic marker.

While the gluten-free diet (GFD) is primarily used to treat celiac disease (CD), recent research suggests it may also offer benefits for autoimmune-related diseases (ARDs), though findings remain inconsistent. This study aimed to investigate the potential protective effect of a GFD against ARDs by Mendelian Randomization (MR) analysis. ⋯ These findings suggest that GFD may help reduce RA risk by modulating specific immune cell populations. However, further research is necessary to clarify the exact mechanisms underlying these associations.

Comparative Study
A comparative analysis of Marburg virus-infected bat and human models from public high-throughput sequencing data.
Marburg virus (MARV) disease (MVD) is an uncommon yet serious viral hemorrhagic fever that impacts humans and non-human primates. In humans, infection by the MARV is marked by rapid onset, high transmissibility, and elevated mortality rates, presenting considerable obstacles to the development of vaccines and treatments. Bats, particularly Rousettus aegyptiacus, are suspected to be natural hosts of MARV. ⋯ Our analysis of differentially expressed genes (DEGs) revealed that these genes are mainly associated with pathways related to the complement system, innate immune response via interferons (IFNs), Wnt/β-catenin signaling, and Hedgehog signaling, which played crucial roles in MARV infection across both models. Furthermore, we also identified several potential compounds that may be useful against MARV infection. These findings offer valuable insights into the mechanisms underlying MARV's pathophysiology and suggest potential strategies for preventing transmission, managing post-infection effects, and developing future vaccines.

Background: Carotene exists naturally in a complex mixture consisting of alpha (α), beta (β), and gamma (γ)-isoforms. Previous studies investigated the effects of individual carotene isomers on bone rather than their actions in a mixture. Purpose: This study explored the bone-protective properties of palm carotene mixture using both two- and three-dimensional co-culture systems. ⋯ Palm carotene mixture also increased bone volume and osteoblast number in the three-dimensional co-culture system. Conclusion: Palm carotene mixture potentially exhibits beneficial effects on bone by accelerating osteoblast proliferation and suppressing osteoclast maturation. The findings of current study serve as the basis for the further validation through animal experiments and human trials.
