HEXIM1 is an essential transcription regulator during human erythropoiesis.

Regulation of RNA polymerase II (RNAPII) activity is an essential process that governs gene expression; however, its contribution to the fundamental process of erythropoiesis remains unclear. hexamethylene bis-acetamide inducible 1 (HEXIM1) regulates RNAPII activity by controlling the location and activity of positive transcription factor β. We identified a key role for HEXIM1 in controlling erythroid gene expression and function, with overexpression of HEXIM1 promoting erythroid proliferation and fetal globin expression.

Influence of WB 315 and crude fish oil (CFO) on growth performance, EPA, DHA, HDL, LDL, cholesterol of meat broiler chickens.

Background And Objectives: Use of antibiotics as growth promoters in animal feeds has been restricted due to the residues in poultry products such as egg and meat, furthermore to the antibiotic resistant of pathogenic bacteria. The prohibition of their use opens the opportunity for the use of non-antibiotic feed additives such as probiotics. The objectives of this study were to investigate the effect of the addition of WB 315 and crude fish oil (CFO) to diets on growth performance, eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), low density lipoproteins (LDL), high density lipoprotein (HDL), and cholesterol levesl of broiler chickens.

Potency of probiotics . and to improve growth performance and business analysis in organic laying hens.

Aim: This study aimed to determine the use of probiotics spp. and as alternative antibiotic growth promoters (AGPs) to improve growth performance and business analysis.

Materials And Methods: This study used a completely randomized factorial design.
