BACKGROUND AND AIM The focus of the study was to investigate the frequencies of homozygous deletions and mutations of p16 gene in gastric carcinomas in the Kashmiri population. METHODS A total of 84 gastric carcinoma patients were screened by the single strand conformation polymorphism (SSCP) technique and later by DNA sequencing to detect mutations of the p16 gene. Also PCR was applied furth...

The unfolded protein response (UPR) is an endoplasmic reticulum (ER)-to-nucleus signaling cascade induced in response to ER stress. The UPR aims at restoring homeostasis, but can also induce apoptosis if stress persists. Infection by human and murine cytomegaloviruses (CMVs) provokes ER stress and induces the UPR. However, both CMVs manipulate the UPR to promote its prosurvival activity and del...

The APC gene at human chromosome 5q21 is responsible for familial adenomatous polyposis coli. Furthermore, sporadic cancers of not only colon but also other digestive organs often contain mutations in the APC gene. A dominant mouse mutation Min that was generated by chemical mutagenesis and causes polyposis in the digestive tract is in the mouse homologue of the human APC gene. The APC mRNA is ...

Gene copy number variation has been discovered in humans, between related species, and in different cancer tissues, but it is unclear how much of this genomic-level variation leads to changes in the level of protein abundance. To address this, we eliminated one of the two genomic copies of 730 different genes in Saccharomyces cerevisiae and asked how often a 50% reduction in gene dosage leads t...

Glioblastoma multiforme (GBM) is the most aggressive type of brain tumor, and the prognosis remains poor. Rearrangement of ROS1 gene, which was shown to have an oncogenic potential, was previously discovered in GBM cell lines. In this pilot study, we aimed to identify the incidence of ROS1 rearrangement in GBM patient tissues to explore novel biomarkers for therapeutic strategy. Formalin-fixed ...

This study investigated the relative contribution of perception/cognition and language-specific semantics in nonverbal categorization of spatial relations. English and Korean speakers completed a video-based similarity judgment task involving containment, support, tight fit, and loose fit. Both perception/cognition and language served as resources for categorization, and allocation between the ...

Most plants encounter stress such as drought and salinity that adversely affect growth, development and crop productivity. The expression of the gene glutathione-s-transferases (GST) extends throughout various protective mechanisms in plants and allows them to adapt to unfavorable environmental conditions. GSTF1 (the first phi GSTFs class) gene expression patterns in the wheat cultivars Mahuti ...
