Fibroblast activation protein drives tumor metastasis via a protease-independent role in invadopodia stabilization.

During metastasis, tumor cells invade through the basement membrane and intravasate into blood vessels and then extravasate into distant organs to establish metastases. Here, we report a critical role of a transmembrane serine protease fibroblast activation protein (FAP) in tumor metastasis. Expression of FAP and TWIST1, a metastasis driver, is significantly correlated in several types of human carcinomas, and FAP is required for TWIST1-induced breast cancer metastasis to the lung.

Identified RP2 as a prognostic biomarker for glioma, facilitating glioma pathogenesis mainly via regulating tumor immunity.

Glioma is the most common primary intracranial tumor in the central nervous system, with a high degree of malignancy and poor prognosis, easy to recur, difficult to cure. The mutation of Retinitis Pigmentosa 2 (RP2) can cause retinitis pigmentosa, it is a prognostic factor of osteosarcoma, however, its role in glioma remains unclear. Based on the data from TCGA and GTEx, we identified RP2 as the most related gene for glioma by WGCNA, and used a series of bioinformatics analyses including LinkedOmics, GSCA, CTD, and so on, to explore the expression of RP2 in glioma and the biological functions it is involved in.

Infectious profiles in pediatric anti-N-methyl-d-aspartate receptor encephalitis.

Anti-N-methyl-d-aspartate receptor autoimmune encephalitis (NMDAR AE) is an antibody-mediated neurological disorder that may be caused by post-herpes simplex virus-1 meningoencephalitis (HSV ME) and ovarian teratomas, although most pediatric cases are idiopathic. We sought to evaluate if other infections precede NMDAR AE by conducting a single-center, retrospective, case-control study of 86 pediatric cases presenting to Texas Children's Hospital between 2006 and 2022. HSV ME (HSV-1 and HSV-2) was a significantly more common preceding infection in the experimental group compared to control patients with idiopathic intracranial hypertension, while there was no difference in remote HSV infection between the two groups.
