c-abl and YWHAZ gene expression in gastric cancer.

چکیده
This study aims to determine the gene expression for c-abl and YWHAZ in gastric cancer and the differences between the c-abl and YWHAZ gene expression inside the tumor versus healthy tissue (at the resection edges). This prospective study included 34 patients with gastric neoplasia, 21 men and 13 women, aged between 49 and 79 years (65.5 years median). After the surgical procedure, in these cases, we collected two tissue samples: one sample was obtained from inside the tumoral tissue and another sample from the gastric tissue, which was identified as normal apparently, as far as possible from the tumor (resection edge). For determining the c-abl and YWHAZ gene expression, we used the quantitative real-time polymerase chain reaction. Regarding the c-abl gene expression in gastric cancer, c-abl expression was identified as lower inside tumor cells comparing to the normal gastric tissue (resection limit). This difference of gene expression emphasize the role of the c-abl gene in normal tissue growth and the involvement in apoptosis induction when alteration of DNA occurs, as a result to different agents actions as stress, ionizing radiations. The loss of expression or even the down-regulation of the c-abl is a fundamental event that leads to genesis and progression of tumors. No significant differences of the YWHAZ gene expression between the tumoral and normal gastric tissue probes were recorded in our study.

Evaluation of the Effect of Curcumin and Imatinib on BCR-ABL Expression Gene in Chronic Human k562 Cells
Background and Aims: Detection of overexpression in tumor-inhibiting genes provides valuable information for leukemia diagnosis and prognosis. Chronic myeloid leukemia (CML) is a stem cell disorder determined by a well-defined genetic anomaly involving BCR-ABL translocation in the Philadelphia chromosome. Curcumin is a chemo-preventive agent for the primary cancer targets, such as the breast, p...
متن کاملIncreased Expression of CYP2E1 Gene in Gastric Cancer May be a Molecular Marker for Mazandaran Province Population
Cytochrome P450 2E1 (CYP2E1) enzyme metabolically activates a large number of low molecular mass xenobiotics probably involved in gastric cancer incidence through activation of procarcinogens. North of Iran is amongst high incidence rate areas of gastric carcinoma where environmental carcinogenic compounds, including agricultural pesticides, are massively used. In this report, we quantitatively...
متن کاملEvaluation of the Prognostic Value and TRIP13 gene Expression in Gastric Cancer
Introduction: Gastric cancer is a major public health issue worldwide. The factors that initiate cancer are not well understood, however aberrant expression of genes is associated with this cancer. TRIP13 plays pivotal roles in meiotic recombination, DNA repair, and cell cycle progression. An increasing body of evidence suggests that TRIP13 may possess functions other than meiosis and mitosis, ...

The aim of the study was to observe the differences between the expression of c-abl inside the tumor and at the resection limit at patients with gastric cancer. We use for our study 20 patients with gastric cancer with ages between 49 and 79 years with a median of 65 years, with a repartition on sexes 12 men and 8 women. We collected after the surgical intervention two samples of tissue: one sa...
