UNLABELLED The Auger electron-emitting radiopharmaceutical 111In-diethylenetriaminepentaacetic acid human epidermal growth factor (111In-DTPA-hEGF) binds the epidermal growth factor receptor (EGFR), is internalized, and translocates to the nucleus. The purpose of this study was to investigate the relationship between EGFR expression, DNA damage, and cytotoxicity in cells exposed to 111In-DTPA-h...

sulfonamides are the first effective chemotherapeutic agents used for several years to cure or prevent systemic bacterial infections. in addition, this agents showed anti-carbonic anhydrase and cause cell cycle perturbation in the g1 phase, disruption of microtubule assembly, suppression of the transcription activator nf-y, angiogenesis and matrix metalloproteinase (mmp). in recent years, novel...

MDA-MB-468 human breast cancer cells lack estrogen receptors, overexpress epidermal growth factor (EGF) receptors, and are growth inhibited by EGF. We show that treatment of MDA-MB-468 cells with EGF leads to inhibition of cell proliferation, fragmentation of DNA into nucleosomal oligomers, and the development of apoptotic morphology. This treatment is associated with increased expression of c-...

A multiplex method using the SNaPshot technique was developed to screen for six common mycobacterial species: Mycobacteria tuberculosis, M. avium, M. intracellulare, M. chelonae, M. kansasii, and M. gordonae. A total of 468 mycobacterial clinical isolates were subjected to analysis for the presence of the six mycobacterial species by the multiplex SNaPshot method. Of the 468 mycobacterial isola...

A series of twenty two novel 1-cyclopropyl-6-fluoro-4-oxo-7-(4-substituted piperazin-1-yl)-1,4-dihydroquinoline-3-carboxylic acid analogues have been synthesized, characterized ((1)H NMR, (13)C NMR and LCMS) and evaluated for their inhibitory activity on the proliferation of human caucasian acute lymphoblastic leukemia cells (CCRF-CEM), breast adenocarcinoma cells (MDA-MB-468) and human colon c...

Triple negative breast cancer (TNBC) is a highly aggressive form of breast cancer resistant to many common treatments. In this study, we compared the effects of 12 phytochemical drugs on four cancer cell lines, and noticed that Cucurbitacin E (CuE) significantly inhibited TNBC cell growth by inducing cell cycle G2/M phase arrest and apoptosis. CuE reduced expression of Cyclin D1, Survivin, XIAP...

In addition, this agents showed anti-carbonic anhydrase and cause cell cycle perturbation in the G1 phase, disruption of microtubule assembly, suppression of the transcription activator Nf-Y, angiogenesis and matrix metalloproteinase (MMP).
