Objective: To investigate the role and significance of FHIT genes depletion, p53 overexpression and HPV16/18 infection in cervical intraepithelial neoplasia (CIN) and cervical carcinoma (CC).
Methods: Tumor samples taken from 52 cases of CIN and 69 cases of CC were processed by immunohistochemistry (SP) to determine the expression of FHIT genes and p53 protein, by in situ hybridization to detect HPV16/18 infection, and were compared with those in 18 cases of normal cervical tissues as control.
Results: (1) The FHIT expression was positive in normal cervical tissue with no depletion occurred, and was 30.
Background & Objective: It is demonstrated that endothelin-1 (ET-1) is synthesized by and released from certain malignant tumor cells, and it plays an important role in growth and development of tumor. This study was designed to investigate the expression of ET-1 in astrocytomas and the relationship between the ET-1 quantity and the grades of astrocytomas.
Method: ET-1 expression was determined in 70 astrocytoma specimens using Streptavidin-Peroxidase method and image analysis technology.
