Published: March 2020

This study aimed to explore the influence of Tryptophanyl-tRNA synthetase (WARS) expression on the proliferation and migration of uveal melanoma (UM) cells, and the potential mechanisms. Bioinformatics analysis based on Gene Expression Omnibus (GEO) database showed that WARS expression in metastatic cancer was significantly higher than that in no-metastatic group. Kaplan-Meier analysis based on The Cancer Genome Atlas (TCGA) database showed that high WARS expression was associated with lower survival. Biological function experiments showed that overexpression of WARS in OCM-1A cells can promote cell proliferation, migration, and invasion, whereas knockdown of WARS in C918 cells showed the opposite effect. Finally, we observed that the up-regulation of WARS induced the activation of phosphatidylinositol 3-kinase/AKT (PI3K/AKT) signaling, whilst depletion of WARS resulted in opponent outcomes. Taken together, our results illustrated that WARS was overexpressed in UM cells and contributed to the viability and motility of UM cells via modulating PI3K/AKT signaling pathway.

In healthy intervertebral discs (IVDs), nerves and blood vessels are present only in the outer annulus fibrosus, while in degenerative IVDs, a large amount of nerve and blood vessel tissue grows inward. Evidence supports that neurogenic inflammation produced by neuropeptides such as substance P and calcitonin gene related peptide released by the nociceptive nerve fibers innervating the IVDs plays a crucial role in the process of IVD degeneration. Recently, non-neuronal cells, including IVD cells and infiltrating immune cells, have emerged as important players in neurogenic inflammation.

Background: The UN General Assembly recognised the human right to water and sanitation through the sixth SDG in 2010. South Kordofan, a state in southern Sudan, faces WASH challenges due to conflict, geographical factors, and inadequate services, impacting over 600,000 residents. Such conflicts are well known for spreading diseases and disrupting WASH-related practices among displaced individuals.

Gestational diabetes mellitus (GDM), defined as glucose intolerance occurring or first detected during pregnancy, affects approximately 8% of pregnancies worldwide. The dysfunction of trophoblasts in pregnancies complicated by GDM is associated with changes in trophoblast cell functions, resulting in compromised proliferation and regulation of the cell cycle. Cyclin B1 (CCNB1), a pivotal controller of the start of mitosis, is crucial in these mechanisms.

Department of Obstetrics and Gynecology, West China Second University Hospital, Sichuan University, Chengdu, Sichuan, P.R. China.

Primary chemoresistance to platinum-based treatment is observed in approximately 33% of individuals diagnosed with ovarian cancer; however, conventional clinical markers exhibit limited predictive value for chemoresistance. This study aimed to discover new genetic markers that can predict primary resistance to platinum-based chemotherapy. Through the analysis of three GEO datasets (GSE114206, GSE51373, and GSE63885) utilizing bioinformatics methodologies, we identified two specific genes, MFAP4 and EFEMP1.

Chromoblastomycosis (CBM) is a chronic neglected fungal disease that causes serious damage to the physical and mental health of patients. 5-Aminolevulinic acid photodynamic therapy (ALA-PDT) has garnered significant attention in the recent era for the treatment of CBM and has exhibited promising effects in several clinical case reports. We established a mice footpad infection model with and analyzed the impact of PDT treatment on the immune response of macrophages using single-cell sequencing.
