5-hydroxymethylcytosine (5-hmC) is a modified form of cytosine recently found in mammalians and is believed, like 5-methylcytosine, to also play an important role in switching genes on and off. By utilizing a newly developed 5-hmC immunoassay, we determined the abundance of 5-hmC in human tissues and compared 5-hmC states in normal colorectal tissue and cancerous colorectal tissue. Significant ...

Serum amyloid A (SAA) is a major acute-phase reactant and apoprotein of high density lipoprotein (HDL). SAA is encoded by a family of three active genes. We examined hepatic expression and searched for extrahepatic expression of the three SAA mRNAs after injection with casein or LPS. Studies using an SAA cDNA, which detects all three SAA mRNAs, revealed that after casein injection liver SAA mRN...

This study aims to detect the mRNA of p53β and Δ133p53 isoforms in three gastric carcinoma cell lines and tissues of superficial gastritis, atrophic gastritis, gastric carcinoma, or paracancerous area. Nested reverse transcription PCR was used to detect the mRNA of p53β and Δ133p53 isoforms in tissues of superficial gastritis, chronic atrophic gastritis, gastric cancer cell lines (SGC-7901, MKN...

LTHOUGH the primary precursors, the intermediates and most of the enzymes involved ir the biosynthetic chain of porphyrins are now known,’,2’3 knowledge of the tissue sites( s) of porphyrin formation is incomplete. Several earlier studies4’5 demonstrated that avian nucleated erythrocytes as well as rabbit bone marrow are active in this respect. Both tissues utilize either glycine and acetate ( ...

Rosmarinic acid is one of the main active components of Coleus blumei and is known to have numerous health benefits. The pharmacological significance of rosmarinic acid and its production through in vitro culture has been the subject of numerous studies. Here, the ability of different tissues to accumulate rosmarinic acid and sustainability in production over long cultivation have been tested. ...

MicroRNAs (miRNAs) can be found in a wide range of tissues and body fluids, and their specific signatures can be used to determine diseases or predict clinical courses. The miRNA profiles in biological samples (tissue, serum, peripheral blood mononuclear cells or other body fluids) differ significantly even in the same patient and therefore have their own specificity for the presented condition...
