This research was conducted to compare the effects of two medicinal plants (peppermint and aloe vera) and antibiotic growth promoter on ileum microflora population and growth performance of broiler chickens. In this experiment, 375 one-day old male broiler chickens (Ross 308) were used on a completely randomized design with 5 dietary treatments which were replicated 5 times with 15 birds per re...

Inactivation of tumor suppressor genes is a frequent event in carcinogenesis. In skin cancer, the CDKN2A gene, which encodes p16INK4A and p14ARF proteins, often silenced by epigenetic abnormalities such as promoter DNA methylation histone deacetylation. The cell cycle regulator plays key role growth metastasis. Unlike gene loss, silencing aberrant modifications can be reversed small-molecule co...

Abstract Phosphorus (P) deficiency is one of the major nutrient stresses restricting plant growth. The uptake P by plants from soil mainly mediated phosphate (Pi) transporters belonging to PHT1 family. Multiple genes diverse species have been shown be strongly up-regulated upon Pi starvation, however, underlying mechanisms for Pi-starvation-induced (PSI) up-regulation not well deciphered most t...

the aim of this study was to analyze the polymorphisms existing in the 5´ flanking region, exonic, and some parts of the intronic regions as well as methylation analysis of the ednrb gene in cattle and goat. these regions were sequenced in three different breeds of cattle including sistani, golpayegani, and holstein and were compared with that of marghoz goat. the results identified that this g...

The human angiotensin II type 1 (AT1) receptor gene was isolated and its promoter function analyzed by deletion mutant promoter/luciferase constructs in transfected Cos 7 cells. We found that epidermal growth factor enhanced the human AT1 promoter activity twofold to threefold. The region between -227 and -366 bp from the 5' end of the cDNA was mapped for a base sequence responsive to the epide...
