BACKGROUND Celecoxib, a selective cyclooxygenase (COX)-2 inhibitor, has a pro-apoptotic effect on colon adenocarcinoma cells via COX-independent mechanisms. MATERIALS AND METHODS The pro-apoptotic effect of N-(2-Aminoethyl)-4-[5- (4-tolyl)-3-(trifluoromethyl)-1H-pyrazol-1-yl] benzenesulfonamide (TT101), a new derivative of celecoxib, was investigated on the HT-29 and SW480 colon adenocarcinom...

background: prostate cancer after lung cancer is the second cause of cancer-associated death in men. in recent years, targeted therapy of cancer has attracted researchers attention. the targeted therapy lead to decrease in side effects of drugs. studies have indicated that targeting peptides for cancer cells represent valuable tools for diagnostic and therapeutic. recently, phage display peptid...

BACKGROUND Sun ginseng (SG), a specific formulation of quality-controlled red ginseng, contains approximately equal amounts of three major ginsenosides (RK1, Rg3, and Rg5), which reportedly has antitumor-promoting activities in animal models. METHODS MTT assay was used to assess whether SG can potentiate the anticancer activity of epirubicin or paclitaxel in human cervical adenocarcinoma HeLa...

Ropivacaine, a new long-acting local anesthetic, is currently being investigated for the treatment of ulcerative colitis. In view of the increased incidence of dysplasia and neoplasia associated with ulcerative colitis, it is important that the medical treatment of these patients does not stimulate cell proliferation further. This study was performed to evaluate the effect of ropivacaine on the...

We have produced a monoclonal antibody CCOL1 that is cytotoxic at a titer of 1:20,000 using human sera as a complement source. CCOL1 reacts to the immunizing colon carcinoma line as well as to one other colon carcinoma line. However, it does not react with another colon adenocarcinoma line or with 28 other cultured tumor cells. It is noncytotoxic to lymphocytes, monocytes, granulocytes, RBC, an...

The serological analysis of recombinant cDNA expression libraries (SEREX) by utilizing a library derived from a human pancreatic adenocarcinoma cell line and IgG antibodies from an allogeneic patient serum led to the identification of 18 genes: 13 of these were known genes, and 5 were unknown genes. In Northern and RT-PCR analyses, we found that the expression of mRNA of 14 genes was elevated i...

Forty-three norditerpenoid alkaloids isolated from Aconitum, Delphinium and Consolida species have been evaluated for their cytotoxic effects on the tumor cell lines CT26 (murine colon adenocarcinoma), SW480 (human colon adenocarcinoma), HeLa (human cervical adenocarcinoma), SkMel25 (human melanoma) and SkMel28 (human malignant melanoma) with several multidrug resistance mechanisms and the non-...
