We have reported protective effects of dietary administration of a powder "CHRP" containing high amounts of beta-cryptoxanthin and hesperidin prepared from a Satsuma mandarin (Citrus unshiu Marc.) juice on azoxymethane (AOM)-induced rat aberrant crypt foci through suppression of crypt cell proliferation and/or induction of detoxifying enzymes. In the present study, we investigated the modifying...

A 63-year-old woman was referred to a breast surgeon with a breast mass discovered incidentally during follow-up study after colon cancer surgery. Invasive adenocarcinoma was revealed on core needle biopsy. Wide excision of the breast including the tumor was performed. On standard histological examination the tumor showed features of moderately differentiated adenocarcinoma. The immunohistochem...

The content of sulfated glycans having 6-O-sulfated GlcNAc residues alters in the course of colonic carcinogenesis. We previously characterized two GlcNAc 6-O-sulfotransferases (SulTs), SulT-a and -b, expressed in colonic normal tissues and adenocarcinomas [Seko et al. (2000) Glycobiology, 10, 919-929]. Levels of the enzymatic activities of SulT-a in normal colonic mucosa are higher than those ...

BACKGROUND Intestinal-type sinonasal adenocarcinoma (ITAC) is an uncommon neoplasm, which resembles adenocarcinoma of the gastrointestinal tract. ITAC occurs sporadically or in association with occupational exposure to hardwood dust and other agents. AIMS To investigate the phenotype and possible pathogenetic mechanisms of primary sinonasal and nasopharyngeal adenocarcinomas by staining for c...

Colorectal cancer is rare in teenagers, especially without known risk factors. Colon cancer in young age is more likely to be diagnosed at advanced-stage, to present unfavorable tumor histology such as mucinous carcinoma, and poor outcome. We report a case of sporadic mucinous adenocarcinoma of the colon in a 19-year-old male patient without any risk factors. He complained of severe left abdomi...
