Corynebacterium sp. U-96 contains a cluster of genes of enzymes for the catabolism of sarcosine to pyruvate.

The sarcosine oxidase gene and nearby genes from Corynebacterium sp. U-96 were determined. The genes for serine hydroxymethyltransferase, the beta, delta, alpha, and gamma subunits of sarcosine oxidase, serine dehydratase, and 10-formyltetrahydrofolate hydrolase are arranged in this order.

Various immunostaining patterns of CD31, CD34 and endoglin and their relationship with lymph node metastasis in oral squamous cell carcinomas.

Background: Intratumoral blood vessels are known to play an important role in cancer growth and metastasis. The discrepancy in previous reports using various endothelial markers individually suggested us to investigate both normal and various tumor areas with a wide panel of vascular markers.

Methods: Here, we used a panel of three antibodies (CD31, CD34, and endoglin) as blood vessel markers to investigate the distribution and properties of blood vessels in normal oral tissues and squamous cell carcinomas.
