During the last years the potential role of in vitro transcribed (IVT) mRNA as a vehicle to deliver genetic information has come into focus. IVT mRNA could be used for anti-cancer therapies, vaccination purposes, generation of pluripotent stem cells and also for genome engineering or protein replacement. However, the administration of IVT mRNA into the target organ is still challenging. The lun...

Signal transducers and activators of transcription (STAT) proteins function in the JAK/STAT signaling pathway and are activated by phosphorylation. As a result of this signaling event, they affect many cellular processes including cell growth, proliferation, differentiation, and survival. Increases in the expressions of STAT5A and STAT5B play a remarkable role in the development of leukemia in ...

objective: the aim of the present study was the production of recombinant lentviruses that express mir-16. after transduction, altered expression levels of mirna and its target protein were analyzed. methods: a dna fragment that contained the mir-16 precursor was cloned in a lentiviral plasmid. lentiviral vector particles were produced by transient calcium phosphate co-transfection of 293t cell...

Wallerian degeneration of injured neuronal axons and synapses is blocked in Wld(S) mutant mice by expression of an nicotinamide mononucleotide adenylyl transferase 1 (Nmnat-1)/truncated-Ube4b chimeric gene. The protein product of the Wld(S) gene localizes to neuronal nuclei. Here we show that Wld(S) protein expression selectively alters mRNA levels of other genes in Wld(S) mouse cerebellum in v...

Background: Mutation of p53 is a frequent event, and mutant exhibits low levels acetylation phosphorylation. This study aimed to investigate the effect histone deacetylase (HDAC) inhibitor, 4-hexylresorcinol (4HR), on phosphorylation carcinoma cells its therapeutic effects in xenograft model. Methods: To determine 4HR p53, western blot analysis was performed using YD-9 YD-15 cells. siRNA used e...

The numerous steps in protein gene expression are extensively coupled to one another through complex networks of physical and functional interactions. Indeed, >25 coupled reactions, often reciprocal, have been documented among such steps as transcription, capping, splicing, and polyadenylation. Coupling is usually not essential for gene expression, but instead enhances the rate and/or efficienc...

runx3, a member of runt-related transcription factor (runx) proteins with tumor suppressor effect, is a tissue–restricted and cancer related transcription factor that regulate cell proliferation and growth, as well as differentiation. in the present study, exogenous run3 was transiently expressed in ags (human gastric adenocarcinoma), with undetectable runx3 protein and in a549 (human lung carc...

BACKGROUND We have demonstrated that growth differentiation factor 9 (GDF9) enhances activin A-induced inhibin β(B)-subunit mRNA levels in human granulosa-lutein (hGL) cells by regulating receptors and key intracellular components of the activin signaling pathway. However, we could not exclude its effects on follistatin (FST) and follistatin-like 3 (FSTL3), well recognized extracellular inhibit...

Exogenous protein expression in mammalian cells is necessary to produce therapeutic proteins and modern medical applications like developing DNA vaccines gene therapy. This study examines the human-Globin (hBG) second intron's capacity for intron-mediated enhancement (IME) various cell lines. Our study's main aim investigate effect of incorporation arrangement intron human Beta-globin into pVAX...
