The use of genetic markers to aid in selection decisions to improve carcass and growth characteristics is of great interest to the beef industry. However, it is important to examine potential antagonistic interactions with fertility in cows before widespread application of marker-assisted selection. The objective of the current experiment was to examine the influence of 2 commercially available...

Background: One of the important issues in aging is sarcopenia characterized by muscle mass and function reduction. The present study investigated the effect of high intensity interval resistance training (HIIRT) on muscular parameters in sarcopenic elderly women. Methods: A total of 30 sarcopenic women aged 60 to 70 years (appendicular skeletal muscle mass index<6.76 kg/m2, hand grip<20 kg) w...

Molecular information using gene variants could support livestock selection to improve productivity. This study aimed identify the in part of MSTN (part third exoncoding region), a known for its significant effect on muscle growth. DNA was isolated from 95 Madura cattle blood samples collected Pamekasan, Madura. PCR used amplify region exon, and one-way sequencing conducted obtain thesequence a...

Abstract Background In dermatomyostis (DM) patients, inflammation, reduced activity, and medication have a negative impact on the musculoskeletal system. Several endocrine factors are involved in muscle growth bone turnover. Objective: We aimed to investigate regulating myogenesis metabolism evaluate possible associations between these factors, strength, functional tests DM patients. Methods co...

In the present study, the polymorphism of myostatin gene (MSTN) in native chickens of Western Azerbaijan Rearing and Breeding Institute was investigated. The blood samples were collected from eighty two randomly selected hens. Genomic DNA was extracted from blood samples and a fragment of myostatin including 599 bp in promoter and exon 1 was amplified using PCR method. Breeding values for body ...

A total of 1,440 fertile eggs were divided randomly and equally into 5 treatment groups; control (no TM) 4 groups: TM1, TM2, TM3, TM4 that thermally subjected to 39°C for 18 h with 65% relative humidity daily, during embryonic days ED 7–11, 11–15, 15–18 7–18, respectively. Out TM conditions investigated, TM1 resulted in a significant improvement expression myogenic factor-5 (Myf5), myoblast det...

Camel racing is one of the popular sports around world and growing rapidly especially in Gulf countries. has adapted itself to harsh draught climate desert. ?his quality camel makes it best choice industry. Pakistani breed Dromedarius camels are as good Omani Sudanese breeds their potential. Myostatin (Growth differentiation factor 8) a protein coded by MSTN gene. Polymorphism play significant ...

Skeletal muscle growth is regulated by both positive and negative factors, such as myogenic regulatory factors (MRFs) and myostatin (MSTN), and involves both hyperplasia and hypertrophy. In the present study, morphological changes during muscle development in Megalobrama amblycephala were characterized and gene expression levels were measured by quantitative real-time polymerase chain reaction ...
