A series of dehydroabietic acid (DHAA) acyl-thiourea derivatives were designed and synthesized as potent antitumor agents. The in vitro pharmacological screening results revealed that the target compounds exhibited potent cytotoxicity against HeLa, SK-OV-3 and MGC-803 tumor cell lines, while they showed lower cytotoxicity against HL-7702 normal human river cells. Compound 9n (IC50 = 6.58 ± 1.11...
Anti-tumor activity of the proteins from Gecko (GP) on cervical cancer cells, and its signaling mechanisms were assessed by viable cell counting, propidium iodide (PI) staining, and Western blot analysis. GP induced the cell death of HeLa cells in a dose-dependent manner while it did not affect the viability of normal cells. Western blot analysis showed that GP decreased the activation of Akt, ...
Isolated HeLa plasma membrane (PM) preparations and extracts containing either cell-surface proteins or lipids were examined for inhibition of adherence of radiolabeled Chlamydia trachomatis serovar E elementary bodies to glutaraldehyde-fixed HeLa monolayers. A dose-dependent adherence-inhibitory activity could be demonstrated with the PM. A urea extract as well as lipids from HeLa cells also i...
Polyadenylated messenger RNA extracted from HeLa cells was hybridized with a mass excess of HeLa DNA. The kinetics of the hybridization reaction demonstrated that most of the messenger RNA is transcribed from nonrepetitive DNA. The amount of messenger RNA hybridized to DNA was measured both with and without prior RNase treatment. Comparison of the results indicates that within the limits of det...
Our laboratory previously used the SEREX method in U937 cells and identified a novel leukemia-associated gene MLAA-34, a novel splice variant of CAB39L associated with acute monocytic leukemia, that exhibited anti-apoptotic activities in U937 cells. Whether MLAA-34 has an anti-apoptotic role in other tumor cells has not yet been reported. We explored whether MLAA-34 exhibited anti-apoptotic eff...
Prior studies identified a cell-surface antigen, p75/150, that exclusively associated with the tumorigenic phenotype of the HeLa parent and the tumorigenic phenotype of the HeLa parent and the tumorigenic segregants of suppressed, nontumorigenic HeLa x human fibroblast cell hybrids. Candidate p75/150 cDNA clones were isolated from a D98/AH.2 (HeLa) cDNA library using oligonucleotide probes deri...
objective: perovskia abrotanoides karel, belongs to the family lamiaceae and grows wild alongside the mountainous roads inarid and cold climate of northern iran. the anti-tumor activity of p. abrotanoides root extract has been shown previously. this study was designed to examine in vitro anti-proliferative and pro-apoptotic effects of flower extract of p. abrotanoides on mcf-7 and hela cell lin...
