Background: The incidence of esophageal squamous cell carcinoma (ESCC) is increasing, causing catastrophic health burdens on communities. Curcumin has shown promise as a therapeutic agent in the treatment of colon, colorectal, pancreatic, and esophageal cancers but it has very poor bioavailability. The application of nano-carriers as drug delivery systems increases curcumin's bioavailability. C...

Objective(s): The protective effect of regular running on sleep deprivation (SD)-induced cognitive impairment has been revealed. In this study, we focused on the effects of regular exercise, sleep deprivation and both of them together on the microRNA-1b (miR-1b) expression and their relation to the behavioral parameters and brain-derived neurotrophic factor (BDNF) expr...

Background: Polarized cells are key to the process of differentiation. Xenopus oocyte is a polarized cell that has complete blue-print to differentiate 3 germ layers following fertilization, as key determinant molecules (Proteins and RNAs) are asymmetrically localized. The objective of this work was to localize Na+, K+-ATPase activity along animal-vegetal axis of polarized Xenopus oocyte and fo...

in the recent years deregulation for micrornas expression pattern have emerged as a possible molecular factor for carcinogenesis. it has been reported that the expression of mir-9 was down-regulated in human gastric adenocarcinoma. to figure out the molecular mechanism of this down regulation, the methylation status in promoters of mir-9 family loci were compared in the human gastric adenocarci...

Mycotoxins produced by fungal species commonly contaminate livestock feedstuffs, jeopardizing their health and diminishing production. Citrinin (CIT) and ochratoxin A (OTA) are mycotoxins produced by Penicillium spp. and commonly co-occur. Both CIT and OTA can modulate immune response by inhibiting cell proliferation and differentiation, altering cell metabolism, and triggering programmed cell ...
