Genomic disorders are genetic diseases that are caused by rearrangements of chromosomal material via deletions, duplications, and inversions of unique genomic segments at specific regions. Such rearrangements could result from recurrent non-allelic homologous recombination between low copy repeats. In cases where the breakpoints flank the low copy repeats, deletion of chromosomal segments is ... more

PPARD encodes for peroxisome proliferator-activated receptor delta, which plays a significant role in controlling lipid metabolism, atherosclerosis, inflammation, cancer growth, progression, and apoptosis. Accumulated evidence suggests that the polymorphism rs2016520 in PPARD is associated with lipid metabolism, obesity, metabolic syndrome, and type 2 diabetes mellitus. The aim of this study ... more

To investigate the role of the P2X receptor in learning and memory dysfunction induced by HIV-1 envelope glycoprotein gp120 (gp120), we established HIV-1-associated dementia (HAD) animal models by intracerebroventricular (ICV) infusion of gp120 in rats. We observed gp120-induced cognitive dysfunction in the radial arm water maze test. Results showed that rats in the gp120 groups had longer ... more

Microarray gene expression technology provides a systematic approach to patient classification. However, microarray data pose a great computational challenge owing to their large dimensionality, small sample sizes, and potential correlations among genes. A recent study has shown that gene-gene correlations have a positive effect on the accuracy of classification models, in contrast to some ... more

Bone desensitization after mechanical loading is essential for bone to adapt to its mechanical environment. However, the desensitization mechanism is unknown. Previous studies suggest that G protein-coupled receptors (GPCRs), including P2Y and parathyroid hormone receptors, play important roles in osteoblast mechanobiology. Thus, for the present research, we examined the role of G protein- ... more

Thymidylate synthase (TYMS) is a key enzyme in nucleotide synthesis and therefore, an important target of many chemotherapeutic agents. Expression of TYMS mRNA is thought to be modulated by a 28-bp tandem repeat polymorphism within its 5'-untranslated region, raising the question of this variant's utility in predicting the efficacy and toxicity of cancer treatment regimens. The aim of the ... more

Zidovudine, the antiretroviral drug used to treat HIV infection, commonly causes adverse effects, such as systemic fever and gastrointestinal alterations. In the present study, the potential role of inosine triphosphate pyrophosphatase (ITPA) gene variant on the incidence of adverse events during antiretroviral therapy (ART) of HIV with zidovudine was discussed. Individuals from Northeastern ... more

We aimed to evaluate the specificity of 12 tumor markers related to colon carcinoma and identify the most sensitive index. Bhattacharyya distance was used to evaluate the index. Then, different index combinations were used to establish a support vector machine (SVM) diagnosis model of malignant colon carcinoma. The accuracy of the model was checked. High accuracy was assumed to indicate the ... more

Glutathione S-transferase (GST) is an important member of phase II metabolic enzymes; GSTM1, GSTT1, and GSTP1 belong to three subfamilies of the GST enzyme. Polymorphisms in GSTM1, GSTT1, and GSTP1 could affect detoxification processes, and increase individuals' susceptibility to cancers. We aimed to investigate the association between GSTM1, GSTT1, and GSTP1 polymorphisms and the risk of ... more

The incidence of liver cancer has gradually risen to a high level in China, and tumor metastasis occurs via multiple pathways. Alpha fetal protein (AFP) is the main biomarker of liver cancer micrometastases. A recent study showed that glypican-3 (GPC3), which is abundant in hepatoma cells, has promising specificity and could be used to determine the presence of malignant cells. The nested ... more
