2,6-Pyridinediylbisalkanamides were synthesized, using diaminopyridine (DAP) as a linker and alkyl chains of varying lengths, that upon self-assembly form submicron-sized sheets and their uptake into the cytoplasm of HeLa cells was studied by confocal microscopy.

Abstract A large common species, Syzygium aqueum , belonging to the genus possesses numerous bioactive phytochemical constituents. Moreover, different parts of this species have been used as folk medicine since centuries ago. In study, a exploration was carried out on plant’s stem bark. Isolation compounds through extraction step with some organic solvents, followed by separation and purificati...

We evaluated the in vitro antiproliferative and apoptotic potential of the ethyl acetate extract (EAE) of Peltophorum africanum, a member of the family Fabaceae (Sond) in order to validate its pharmacological use. Antiproliferation of human breast (MCF-7), colon (HT-29) and cervical (HeLa) cancer cell lines by EAE was investigated using the Cell Titer-Blue viability assay and the mechanism of a...

Cervical cancer ranks third in incidence worldwide and is the most frequent gynecological developing countries. This study aimed to investigate effect of crocin on resistance HELA/Ara-C cells chemo-agent Ara-C. which was defined as Ara-C-resistant HELA cell line, were treated with crocin. After that, proliferation, apoptosis, cycle assay examined by MTT assay, AO/EB staining, flow cytometry, re...

UNLABELLED Herpes simplex virus 1 (HSV-1) can undergo a productive infection in nonneuronal and neuronal cells such that the genes of the virus are transcribed in an ordered cascade. HSV-1 can also establish a more quiescent or latent infection in peripheral neurons, where gene expression is substantially reduced relative to that in productive infection. HSV mutants defective in multiple immedi...

objective(s) nonviral vector can be an attractive alternative to gene delivery in experimental study. in spite of some advantages in comparison with the viral vectors, there are still some limitations for efficiency of gene delivery in nonviral vectors. to determine the effective expression, the recombinant escherichia coli lacz genes were cloned into the different variants of pcdna3.1 and then...

We describe the use of small interfering RNAs (siRNAs) to downregulate Hand L-ferritin levels in HeLa cells. They repressed Hand L-ferritin expression to about 20-25% of the background level, both in stable and transient transfections. HeLa cells transfected with Hand L
