Multiple regions in the short arm of chromosome 3 are frequently deleted in a variety of solid tumors including gallbladder carcinoma (GBC). RNA binding motif, single‑stranded interacting protein 3 (RBMS3), a tumor suppressor gene (TSG), is located in this region. However, the role of RBMS3 in GBC remains unclear.

Molecular biomarkers combined with histopathological examination are of critical importance in the diagnosis and treatment of gliomas. Although recent studies have shown that many tripartite motif-containing (TRIM) family proteins could regulate the cell cycle, cell proliferation, and differentiation in cancers, the precise role of TRIM21 has been unknown in glioma. In this study, we analyzed TRIM21, which was upregulated in gliomas and identified its role in tumor proliferation, migration and drug resistance.

Background: Glioma is the most common and aggressive primary brain tumor with polygenic susceptibility. The cytoplasmic/nuclear shuttling protein, SLC2A4RG (SLC2A4 regulator), has been identified in the 20q13.33 region influencing glioma susceptibility by genome-wide association studies (GWAS) and fine mapping analyses.

Background: LGALS3 promotes tumor progression in diverse cancers. However, the involvement of LGALS3 in glioblastoma has not yet been broadly illuminated.

Methods: Microarray was performed to detect the gene expression profiles of radioresistance in T98G cells and identified a universally upregulated gene, .

Glioma is the most aggressive and malignant primary brain tumor in adults. In the present study, we identified a vital oncoprotein, capping actin protein, gelsolin-like (CapG), and investigated its roles in the prognosis, proliferation and metastasis in glioma. The mRNA and protein levels of CapG were significantly increased in human glioma, and higher CapG expression was an independent prognostic factor for predicting unfavorable prognosis.

In this study, we conducted a genome-wide scan of single nucleotide polymorphisms (SNPs) to identify coding variants that is associated with the risk of glioblastoma (GBM), the most common and most malignant subtype of glioma. We genotyped 1038 GBM cases and 1008 controls in a Chinese Han population using Illumina HumanExome Beadchip v1.0.

Frequent loss of multiple regions in short arm of chromosome 3 is found in various tumors including gastric cancer (GC). RNA binding motif, single-stranded interacting protein 3 (RBMS3) is a tumor suppressor gene located in this region and mediates cancer angiogenesis. However, the role of RBMS3 in GC remains unclear.

Over 14 common single nucleotide polymorphisms (SNP) have been consistently identified from genome-wide association studies (GWAS) as associated with glioma risk in European background. The extent to which and how these genetic variants can improve the prediction of glioma risk has was not been investigated. In this study, we employed three independent case-control datasets in Chinese populations, tested GWAS signals in dataset1, validated association results in dataset2, developed prediction models in dataset2 for the consistently replicated SNPs, refined the consistently replicated SNPs in dataset3 and developed tailored models for Chinese populations.

Glioma is the most malignant brain tumor and glioblastoma (GBM) is the most aggressive type. The involvement of N-myc (and STAT) interactor (NMI) in tumorigenesis was sporadically reported but far from elucidation. This study aims to investigate roles of NMI in human glioma.

Purpose: Eukaryotic elongation factor 1 alpha-2 (eEF1A2) is a protein translation factor involved in protein synthesis. It is overexpressed in various cancers, which indicates potential vital functions in tumorigenesis and progression. Our study aims to investigate the expression levels of eEF1A2 in gastric cancer and its roles in clinical practice.

Background: Glioblastoma (GBM) is the most common and lethal intracranial malignancy in adults, with dismal prognosis despite multimodal therapies. Tectonic family member 1 (TCTN1) is a protein involved in a diverse range of developmental processes, yet its functions in GBM remain unclear. This study aims to investigate expression profile, prognostic value and effects of TCTN1 gene in GBM.

Background: Malignant glioma is a common and lethal primary brain tumor in adults. Here we identified a novel oncoprotein, vesicle-associated membrane protein 8 (VAMP8), and investigated its roles in tumorigenisis and chemoresistance in glioma.

Methods: The expression of gene and protein were determined by quantitative PCR and Western blot, respectively.

Rice (Oryza sativa) has unique floral patterns that contribute to grain yield. However, the molecular mechanism underlying the specification of floral organ identities in rice, particularly the interaction among floral homeotic genes, remains poorly understood. Here, we show that the floral homeotic gene OsMADS16 (also called SUPERWOMAN1, SPW1, a B-class gene) acts together with the rice C-class genes OsMADS3 and OsMADS58 in specifying floral organ patterning.

Reproductive organ development is one of the most important steps in the life cycle of plants. Studies using core eudicot species like thale cress (Arabidopsis thaliana) and snapdragon (Antirrhinum majus) have shown that MADS domain transcription factors belonging to the AGAMOUS (AG) subfamily regulate the identity of stamens, carpels, and ovules and that they are important for floral meristem determinacy. Here, we investigate the genetic interactions between the four rice (Oryza sativa) AG subfamily members, MADS3, MADS13, MADS21, and MADS58.
