Background: Human papilloma virus infection is associated with genesis and malignant potential of cervical cancer. E6 and E7 oncogens are known to bind to p53 and retinoblastoma gene products, abrogating their functions as tumor suppressors, leading to an abnormal cell cycle machinery. Roles of the p53 homolog p63 have also been postulated, E6 expression leading to TAp63b degradation allowing anchorage independent growth. Molecular studies correlated with clinicopathological factors are important to determine prognosis and treatment strategies, but results have been controversial and need to be clarified. Aim: To investigate expression of p53 and p63 in cervical squamous cell carcinomas in correlation with age, FIGO staging, morphology, and cancer cell proliferation. Materials and Methods: Expression of p53 and p63 immunohistochemical staining in a total of 56 paraffin-embedded tissues of cervical squamous cell carcinomas from Dr. Sardjito General Hospital Indonesia, was evaluated for correlation with clinicopathological parameters. The Mann-Whitney test was used to compare the percentage of p53 and p63 expression with patient age, FIGO staging and morphology and to compare mean p53 and p63 expression. The Spearman correlation test was applied to correlate p53 and p63 expression with that of Ki-67. A p-value of <0.05 was considered statistically significant. Results: There were significant associations between p53 expression with age (p=0.019) and FIGO staging (p=0.026), but not with with morphology or Ki-67 expression. There were no links between p63 expression and age, morphology, FIGO staging or Ki-67. Conclusions: This study indicated that p53 has a prognostic value in cervical squamous cell carcinomas given the relation with FIGO staging.

The effect of alpha-lipoic acid on expression of VCAM-1 in type 2 diabetic rat

Macrovascular diabetes complications are generally caused by a process called atherosclerosis. Evidences suggest that to initiate atherosclerosis, oxidated low-density lipoprotein (oxLDL) has to promote the expression of adhesion molecule. Several studies have evidenced the relevance of oxidative stress and atherosclerosis. However, the protective effect of alpha-lipoic acid (ALA) at atherosclerosis still needs to be explored. This study is aimed at investigating the concentration of plasma oxLDL and the expression of adhesion molecule of type 2 diabetes mellitus (DM) using rat model. Eighteen male rats were segregated into three groups labeled as control group, DM group and DM+ALA group. Type 2 diabetes was induced by intraperitoneal injection of streptozotocin (50 mg/kg) followed by nicotinamide (110 mg/kg). ALA was administered at a dose of 60 mg/kg body weight/ day throughout the feeding period of 3 weeks. Plasma oxLDL concentration was measured by enzyme-linked immunosorbent assays and expression of vascular cell adhesion molecule-1 (VCAM-1) was measured by immunohistochemistry. Expression of abdominal aortic adhesion molecule was assessed by calculation with Adobe Photoshop CS3. Analysis of variance test was used to compare the concentration of plasma oxLDL and expression of adhesion molecule. A P-value of 0.05 was considered statistically significant. Plasma oxLDL was lower in diabetic rat+ALA compared with the diabetic rat. Percentage of area VCAM1 in DM+ALA group was lower than DM group. There were no significant differences between groups in intensity of VCAM-1. In conclusion, ALA showed protective effects against early atherosclerosis in diabetic rats.
