GRM1 (Glutamate Metabotropic Receptor 1)

Ultimately, these findings suggest that canine OMM does not heavily rely on mGluR1 for tumorigenesis or progression. Differential GLS1 protein expression warrants further investigation with protein quantification.

A competing endogenous RNA (ceRNA) network involving miRNAs (e.g., miR-16-5p, miR-126-5p) and lncRNAs (e.g., AC008124.1, AC064799.2, AGAP11) potentially modulates their expression. This study identifies seven novel candidate biomarkers dysregulated in endothelial cells under combined BCR-ABL and exosomal stimulation, shedding light on the molecular crosstalk between leukemic cells and the vascular niche.

Correlation analysis revealed a negative association between GPR89A and miR-199a-5p expression, and a positive association between GPR89A and mGluR1. Mechanistically, miR-199a-5p directly targets GPR89A mRNA to suppress its expression, thereby downregulating mGluR1 and reducing glutamate levels.ConclusionsThese findings uncover a novel regulatory axis linking GPR89A overexpression, glutamate metabolic reprogramming, and the development of acquired sorafenib-resistant HCC.

Knockdown of tRNase ZL by siRNA attenuated the suppression effect of sgRM1, sgRM2 and sgRM6 on the MALAT1 RNA level. We also demonstrated that the effective sgRNAs sgRM1, sgRM2 and sgRM6 reduce A549 cell viability.

Like the effects of Nrf2 knockdown, Atox1 was found to play a pivotal role in the Cu-mediated induction of SLC7A11. Our findings indicate that intratumoral Cu influences the expression of SLC7A11 and may play a role in tumor progression.

Cartilage tumors are a group of mesenchymal neoplasms characterized by tumor cells that produce cartilage matrix.The molecular pathology of cartilage tumors, as outlined in the 5th edition WHO classification, has been significantly updated.Key updates include: isocitrate dehydrogenase 1/2 mutations in enchondoma and chondrosarcoma, H3F3B mutations in chondroblastoma, NCOA2 rearrangements in mesenchymal chondrosarcoma, and GRM1 gene fusion and promoter replacement are associated with chondromyxoid fibroma, etc.Since these molecular abnormalities serve as specific diagnostic and differential diagnostic markers, this article focuses on recent advances in the molecular characterization of cartilage tumors.

Furthermore, we conducted experiments in vitro and in vivo experiments, which encompassed CCK-8, colony formation, flow cytometry apoptosis, intracellular calcium ion measurement, and xenograft tumor experiments utilizing nude mice, to validate the function of Panaxadiol in suppressing the growth of GBM via the modulation of calcium ion levels. This study not only revealed the anti-GBM mechanisms of Panaxadiol through network pharmacology but also validated its inhibitory effects on GBM via calcium ion release through in vitro and in vivo experiments.

A benign blue nevus or intermediate-grade blue melanocytoma is frequently found on the side of the central mass. Loss of nuclear BAP1 immunoreactivity is a poor prognostic factor.

GRM1 gene rearrangements can be detected using FISH break-apart probes in approximately 75% of cases, and immunohistochemical detection of GRM1 protein over-expression is a sensitive diagnostic method. The gene fusion was not detected by targeted RNA sequencing, due most probably to the complexity of fusion mechanism, and is not yet a reliable method for confirming a diagnosis of CMF in the clinical setting.

In summary, we have successfully identified and comprehensively analyzed a gene signature associated with glutamine metabolism in CRC for the first time. This gene signature consistently and reliably predicts the prognosis of CRC patients, indicating its potential as a metabolic target for individuals with CRC.

In this report, we present a case of GRM1-rearranged chondromyxoid fibroma that also exhibited FGF23 expression via in situ hybridization, posing significant diagnostic challenges during workup of the initial core biopsy. We hope that this case can serve as an educational resource, shedding light on a rare diagnostic pitfall.

Case 1: 73-year-old woman, January 2014 retroperitoneal leiomyosarcoma of the ureter - R0 en bloc resection with partial resection of the ureter and left hemicolectomy - Transcriptome-guided adjuvant treatment: Sorafenib and Riluzole due to GRM1 gene overexpression - Scapular recurrence with bone infiltration in Sept...Treatment with Tazemetostat in December 2022...- Neoadjuvant chemotherapy and radiotherapy treatment, R0 wide surgery with adequate preservation of functionality and IORT - Early chest wall dermal/subcutaneous recurrence (resected) after initiation of immunotherapy – Nivolumab – due to a favorable profile for immunotherapy in tumor transcriptome - Genome of recurrence: BRAF V600E mutation. Treatment with Dabrafenib + Trametinib... STS are tumors with complex surgical and oncological management and a poor response to conventional chemotherapy protocols. Given its heterogeneity, precision oncology through molecular profiling with next-generation massive sequencing (panels for tumor genome and transcriptome) allows the development of personalized therapeutic strategies in patients with STS, and opens up the possibilities for targeted treatments for molecular alterations, immunotherapy and the development of new agents.
