We studied three keratin (K) gene candidates, K13, K19, and K20 mRNAs, for detecting micrometastases in cervical lymph nodes (LNs) by reverse transcriptase-polymerase chain reaction (RT-PCR). Of 166 histologically metastasis-negative nodes, 24 micrometastatic LNs (14. 4%) were detected based on K13 gene expression. Keratin 19 mRNA is an inadequate marker(More)
The modulating effects of dietary feeding of two flavonoids, diosmin and hesperidin, both alone and in combination, during the initiation and post-initiation phases on colon carcinogenesis initiated with azoxymethane (AOM), were investigated in male F344 rats. Animals were initiated with AOM by weekly s.c. injections of 15 mg/kg body wt for 3 weeks to(More)
BACKGROUND AND PURPOSE Rheumatoid arthritis (RA) is an autoimmune disorder involving subsets of activated T cells, in particular T helper (Th) 1 and Th17 cells, which infiltrate and damage tissues and induce inflammation. Prostaglandin E(2) (PGE(2)) enhances the Th17 response, exacerbates collagen-induced arthritis (CIA) and promotes inflammatory pain. The(More)
The modifying effects of the two flavonoids diosmin and hesperidin given during the initiation and postinitiation phases of oral carcinogenesis initiated with 4-nitroquinoline 1-oxide (4-NQO) were investigated in male F344 rats. The compounds were tested alone and in combination. At 6 weeks of age, animals were divided into experimental and control groups(More)
The International Union Against Cancer (UICC) does not define the number of sections required from each regional lymph node to record pTNM classification. This study was designed to clarify the incidence of occult metastasis and to assess the pN upgrading of patients with oral cancer. Ultimately, this study led to a proposal for appropriate semiserial(More)
Anticardiolipin antibodies (aCL) found in sera from patients with SLE react with cardiolipin (CL) in the presence of a 50-kDa serum cofactor. The cofactor, which was identified to be beta 2-glycoprotein I by sequencing the N-terminal amino acids, not only enhances CL binding by antibodies in SLE but also depresses it by antibodies associated with syphilis.(More)
OBJECTIVE To examine the concentration of the soluble form of the Fas molecule (sFas) in the serum and synovial fluid of patients with rheumatoid arthritis (RA) and osteoarthritis (OA). METHODS The concentration of sFas in the serum of 15 normal subjects and in the synovial fluid and serum of 45 RA patients and 13 OA patients was determined. The(More)
Id proteins are inhibitors of basic helix-loop-helix transcription factors and generally stimulate cell proliferation and inhibit differentiation. We have shown that ectopic expression of Id-1 in murine mammary epithelial cells resulted in loss of differentiation and gain of invasive and proliferative abilities. Moreover, Id-1 was highly expressed in(More)
To identify and characterize anti-citrullinated glucose-6-phosphate isomerase (GPI) peptide antibodies in patients with rheumatoid arthritis (RA). Nine GPI arginine-bearing peptides in human GPI protein were selected and cyclic citrullinated GPI peptides (CCG-1-9) were constructed. Samples were obtained from RA (n = 208), systemic lupus erythematosus (SLE)(More)
