Rabbit Anti-Human VILIP1 (a.a. 121-191) Polyclonal antibody

Background/Aims: This study aims to comparing the gene expression profiles and molecular interactions among gastric cardiac adenocarcinomas (GCA), gastric noncardiac adenocarcinomas (GNCA) and their adjacent normal tissues. Methodology: Gene expression profile of GSE29272 was downloaded from Gene expression omnibus. Differentially expressed genes (DEGs) were identified at the cut-off of p-value <= 0.01. Gene ontology (GO) enrichment analysis was further performed for the DEGs, and then the binding sites of the transcriptional factors and the specific protein-protein interactions were analyzed. Results: Total 1024 DEGs were screened, including 741 up-regulated genes and 283 down-regulated genes. VSNL1 (visinin-like protein-1) is expressed relatively higher in the GNCA and could be its molecular biomarker, as KRT14 (cytokeratin 14) in the GCA. GO analysis showed that the analogous cancer-relevant factors network appears in these two cancer subgroups. The DEGs in the GCA tend to be bound by SPIB and ZNF354C. FN1 lies in the center of the protein-protein interaction networks of the two cancer subgroups. Conclusions: We found out the RNA expression level of the two gastric cancers varied greatly from the normal tissues while gene expression profile of them were very similar, however, the different biomarker and transcriptional factors indicate the differences of two mechanisms.

Retinitis pigmentosa (RP) is a group of clinically and genetically heterogeneous disorders characterised by night blindness, constriction of visual field, and dystrophic changes of the retina. Previous genetic studies have shown extensive allelic and non-allelic genetic heterogeneity of RP. Here we describe an Indian family with multiple consanguineous marriages and a total of four patients with autosomal recessive (AR) RP. The homozygosity mapping strategy was successfully used and indicated close linkage between the disease locus and D2S380, D2S441, D2S291, and D2S1394 with maximum lod scores between 1.51-3.07 at theta=0.00. The analysis of multiply informative meioses maps the locus (RP28) for ARRP in this family between D1S1337 and D2S286 on 2p11-p15. The involvement of visinin (VSNL1), a promising candidate gene assigned to chromosome 2p by previous studies, has been excluded by the absence of linkage.
