Genetic alteration in TP53 gene can proliferate the tumor formation in gastric cancer and the frequency of these somatic mutations can vary in different geographical populations. In the present study, sequencing of the coding regions of TP53 gene, real time gene expression and immunohistochemistry analysis were performed in gastric tumor samples. H. pylori infected tumor, with or without cagA geno
Aim: The aim of this study is to identify the AKT1 gene mutation driven pathogenicity in gastric cancer for Mizo population. Methods: 50 diffuse-type gastric tumors were analyzed for AKT1 exon 2 and 14 mutations. Cell-cycle aberration was analyzed in the AKT1-mutated samples and the stability of the protein as well as exonic splicing enhancer motifs were examined. Results: The novel mutations, 155
Connected Autonomous Vehicles (AV)s can transform urban transportation systems and have the potential to improve the safety and efficiency, since human errors and distractions are removed. However, these systems are vulnerable to model uncertainties, communication impairments associated with the wireless communication, and external disturbances. As a result, vehicles need to drive at low speed and
IntroductionThe study was carried out to identify the polymorphisms in mitochondrial genes (ATPase and ND1) in type 2 Diabetes Mellitus (T2DM) from Mizo population and to correlate the involvement of demographic factors.FindingsIn the present study, 58 patients and 50 healthy volunteers were considered. The mutations observed were mostly base substitutions and were similar as reported for other po
The enzymes encoded by glutathione S-transferase mu 1 (GSTM1) and theta 1 (GSTT1) genes are involved in the metabolism of wide range of carcinogens that are ubiquitous in the environment. Homozygous deletions of the GSTM1 and GSTT1 genes are commonly found and result in lack of enzyme activity. This study was undertaken to evaluate the association between GSTM1, GSTT1 and GSTP1 gene polymorphism a
Silver and gold nanoparticles of Jasminum nervosum L. had unique optical properties such as broad absorbance band in the visible region of the electromagnetic spectrum. Characterization of the nanoparticles using UV spectrophotometer, Fourier transform infrared spectroscopy, X-ray diffraction, and transmission electron microscopy confirmed that the particles were silver (AgNPs) and gold (AuNPs) ra
BackgroundRetrospective studies of archived human specimens, with known clinical follow-up, are used to identify predictive and prognostic molecular markers of disease. Due to biochemical differences, however, formalin-fixed paraffin embedded (FFPE) DNA and RNA have generally been extracted separately from either different tissue sections or from the same section by dividing the digested tissue. O
Isolation of DNA from blood and buccal swabs in adequate quantities is an integral part of forensic research and analysis. The present study was performed to determine the quality and the quantity of DNA extracted from four commonly available samples and to estimate the time duration of the ensuing PCR amplification. Here, we demonstrate that hair and urine samples can also become an alternate sou
BackgroundMizoram has the highest incidence of cancer in India. Among women, breast cancer is most prevalent and the state occupies fifth position globally. The reason for high rate of cancer in this region is still not known but it may be related to ethnic/racial variations or lifestyle factors.MethodsThe present study aims to identify the candidate mitochondrial DNA (mtDNA) biomarkers—ND1and ATP
Gastric cancer is one of the most common malignancies in India. DNA repair gene or xenobiotic pathway gene polymorphisms have recently been shown to affect individual susceptibility to gastric cancer. Here, the possible interaction between common polymorphisms in X-ray repair cross complementing group I (XRCC1) gene and glutathione S-transferase (GST) genes (GSTM1, GSTT1 and GSTP1), smoking and al
Background: The aim of this study was to evaluate the risk of gastric cancer associated with individual or combined glutathione S-transferases (GSTs) polymorphism and their interaction with environmental factors. Materials and Methods: Genotyping by PCR was carried out for 80 cases and controls each for GSTM1, GSTT1, and GSTP1 polymorphism and mapped for gene—environment association studies. The s
Background: Hereditary thrombocytopenias constitute a genetically heterogeneouscause of increased bleeding. We report a case of a 17-year-old boy suffering fromsevere macrothrombocytopenia throughout his life. Whole genome sequencing revealed the presence of two compound heterozygous variants in GNE encoding the enzyme UDP-N-acetyl-glucosamine-2-epimerase/N-acetylmannosamine kinase, crucial for si
Background: Digital breast tomosynthesis (DBT) improves breast cancer (BC) detection compared to mammography, however, it is unknown whether this reduces interval cancer rate (ICR) at follow-up. Methods: Using individual participant data (IPD) from DBT screening studies (identified via periodic literature searches July 2016 to November 2019) we performed an IPD meta-analysis. We estimated ICR for
BACKGROUND: Gastric cancer (GC) is one of the most frequently diagnosed digestive tract cancers and carries a high risk of mortality. Acetaldehyde (AA), a carcinogenic intermediate of ethanol metabolism contributes to the risk of GC. The accumulation of AA largely depends on the activity of the major metabolic enzymes, alcohol dehydrogenase and aldehyde dehydrogenase encoded by the ADH (ADH1 gene
BACKGROUND: The role of adenomatous polyposis coli (APC) gene in mitosis might be critical for regulation of genomic stability and chromosome segregation. APC gene mutations have been associated to have a role in colon cancer and since gastric and colon tumors share some common genetic lesions, it is relevant to investigate the role of APC tumor suppressor gene in gastric cancer.METHODS: We invest
Mitochondrial DNA (mtDNA) is known for its high frequencies of polymorphisms and mutations as it is prone to oxidative stress. The aim of the present study is to assess the novel mutations in mitochondrial genes from blood samples among the breast cancer patients from a less studied Northeast Indian population. D, B, L haplogroups were observed in the cancer samples and a total of 44 mtDNA D-loop
Mutations in mitochondrial D-loop region of DNA (mtDNA) may serve as a potential sensor for cellular DNA damage and marker for cancer development. We investigated the restriction fragment length polymorphism (RFLP) pattern of the D-loop region in the blood samples of breast cancer patients among Mizoram population. Significant differences were observed among breast cancer and healthy blood samples
For lossless universal source coding of memoryless sequences with an a priori unknown alphabet size (multialphabet coding), the alphabet of the sequence must be described as well as the sequence itself. Usually an efficient description of the alphabet can be made only by taking into account some additional information. We show that these descriptions can be separated in such a way that the encodin
Background: Mutations in the CDH1 and the role of E-cadherin proteins are well established in gastric cancer. Several in silico tools are available to predict the pathogenicity of the mutations present in the genes with varying efficiency and sensitivity to detect the pathogenicity of the mutations. Objective: Our objective was to identify somatic pathogenic variants in CDH1 involved in Gastric Ca
