The emerging role of long non-coding RNAs in schizophrenia.

Schizophrenia (SZ) is a severe psychiatric disorder which is contributed by both genetic and environmental factors. However, at present, its specific pathogenesis is still not very clear, and there is a lack of objective and reliable biomarkers. Accumulating evidence indicates that long non-coding RNAs (lncRNAs) are involved in the pathophysiology of several psychiatric disorders, including SZ, and hold promise as potential biomarkers and therapeutic targets for psychiatric disorders.

Exploration of the relationship between hippocampus and immune system in schizophrenia based on immune infiltration analysis.

Immune dysfunction has been implicated in the pathogenesis of schizophrenia (SZ). Despite previous studies showing a broad link between immune dysregulation and the central nervous system of SZ, the exact relationship has not been completely elucidated. With immune infiltration analysis as an entry point, this study aimed to explore the relationship between schizophrenia and the immune system in more detail from brain regions, immune cells, genes, and pathways.

USP18 and USP20 restrict oHSV-1 replication in resistant human oral squamous carcinoma cell line SCC9 and affect the viability of SCC9 cells.

In this study, we discovered that two human oral squamous carcinoma cell (OSCC) lines, SCC9 and SCC25, exhibited varied levels of permissivity to oncolytic HSV-1 T1012G replication and the differential virus yields may associate with the constitutive accumulation of two deubiquitinating enzymes USP18 and USP20 in tumor cells. USP18 and USP20 belong to the ubiquitin-specific protease family, mediating the deubiquitination of targets and promoting antiviral responses. Depletion of USP18 or USP20 in SCC9 cells increased T1012G virus yields; overexpression of USP18 or USP20 in SCC25 cells down-regulated T1012G virus replication.

High accumulation of Mx2 renders limited multiplication of oncolytic herpes simplex virus-1 in human tumor cells.

Increasing studies demonstrated that oncolytic activities of oHSV-1 are limited to the capacity of virus replicating in tumors. In order to potentiate the oHSV-1 oncolytic activity and expand the application of oHSV-1 treatment in multiple types of tumors, it is critical to explore the potential factors or mechanisms mediating tumor resistance to oHSV-1 infection. Here we evaluated the levels of oHSV-1 multiplication in various tumor cell lines and showed that glioblastoma cell line A172 had the lowest virus yields but intrinsically accumulated the highest levels of Mx2 protein.

Association between Normal Thyroid Hormones and Diabetic Retinopathy in Patients with Type 2 Diabetes.

The relationship between normal thyroid function and type 2 diabetes mellitus (T2DM) has been a particular focus for concern. The present study determined the relationship between thyroid hormone levels and the prevalence of diabetic retinopathy (DR) in T2DM patients. A cross-sectional study ( = 633) was performed in Xi'an, Shaanxi Province, China.
