Down regulation of endothelial adhesion molecules in node positive breast cancer: possible failure of host defence mechanism.

Endothelial cell adhesion molecules (CAMs) are important in tumorigenesis and host defense mechanism. Their status in breast cancer with regard to nodal invasion is not yet known. Hence we looked at the expression of three important CAMs: VCAM, ICAM and E-selectin.

Cadherins as predictive markers of nodal metastasis in breast cancer.

Adhesion molecules, particularly cadherins play a pivotal role in cancer invasion and metastasis. Because the therapeutic management of tumors with and without nodal metastasis differs considerably, our idea was to identify tumors with metastatic potential. We studied the expression of E-cadherin and P-cadherin immunohistochemically in 51 cases of breast cancer that included 29 node-negative and 22 node-positive cases.

Elevated serum glycosaminoglycans with hypomagnesemia in patients with coronary artery disease & thrombotic stroke.

Elevated levels of serum glycosaminoglycans (GAG), associated with hypomagnesemia were observed in patients of proven CAD and thrombotic stroke in Kerala. Serum lipid profile was normal in the majority of these patients, indicating that elevated serum GAG may be an even more reliable indicator of atherosclerosis than elevated serum total cholesterol or LDL cholesterol. Autopsy samples of carotid artery and aorta which had atheroma showed significantly higher GAG when compared to samples which showed no atheroma.
