In this study, dual therapeutic-loaded GE11 peptide-conjugated liposomes were developed and applied to enhance therapeutic efficacies of standard-of-care regimens for the treatment of laryngeal cancer. The therapeutic strategy used here was a combination treatment with the chemotherapeutic docetaxel (DTX) and siRNA against the ABCG2 gene that regulates multidrug resistance in many tumor types. ...

A 30 to 40% increase in glucose uptake and lactic acid production was observed during a 48-h period immediately following inoculation of feline fibroblasts and HEp-2 cells with feline leukemia virus. There was no evidence of morphological alterations in either cell type. Immunofluorescent procedures to detect feline leukemia virus group-specific antigen revealed that the feline and HEp-2 cells ...

objective: a number of studies have demonstrated the potential antitumor effects of saffron and its constituents on different malignant cells in vitro. it has been reported that a novel glycoconjugate isolated from corms and callus of saffron possesses cytotoxic activity against different tumor cellswith nitric oxide (no) production. these data suggest that the cytotoxic effect of saffron extra...

In the presence of 3-isobutyl-l-methylxanthine, VIP produced a dose-related (3 X 10(-9)-10(-7) M) increase (8-fold) in cAMP production in isolated HEp-2 cells incubated at 15 degrees C in KRP buffer. Among the peptides structurally related to VIP, including secretin (10(-7) M), pancreatic glucagon (10(-6) M), PHI, somatostatin-14 (10(-6) M), hpGRF (10(-8)-4 X 10(-6) M), GIP (2 X 10(-7) M), only...

Antisera to the human erythrocyte Glc transporter immunoblotted a polypeptide of Mr 55,000 in membranes from human hepatocarcinoma cells, Hep G2, human fibroblasts, W138, and murine preadipocytes, 3T3-L1. This antisera immunoprecipitated the erythrocyte protein which had been photoaffinity labeled with [3H]cytochalasin B, immunoblotted its tryptic fragment of Mr 19,000, and immunoblotted the de...
