        A tremendous increase in the human population has put poultry industry under an increased pressure to meet steep increase in the demand. Poultry is contributing 25% of the total world’s meat production and lesser cost of investment per bird makes it more suitable for the further breeding programmes. Major poultry diseases frequently lead to cardiac damage and cause huge economic losses to poultry industry due to mortality. The in vitro embryonic stem cell (ESC) technology has a futuristic approach for homogeneous populace of differentiated cells, for their further transplantations. During in vitro conditions the differentiated cell populace can be used in grafting and transplantation processes to regenerate damaged tissues. Therefore, the current study targeted the use of spermatogonial stem cells (SSCs) in the poultry production system through cardiac regeneration. The current study will also open new boulevard for the similar kind of research in other livestock species for the management of heart diseases.

        Selection based on phenotype in the traditional manner does not help in tracking the selected gene. Molecular genetics has revolutionized the old established breeding techniques. A new epoch of molecular markers has been acquainted for genetic improvement of livestock. This study is engaged on the neoteric molecular markers used in various fields of livestock. DNA markers are more encouraging in selecting genomes that have recombination events close to the target gene. Molecular markers rely on DNA assay and are better than the morphological and biochemical markers. In this study DNA-based molecular markers developed during the past decagons for animal genome analysis are reviewed. Mapping of molecular markers provide a framework, required for its subsequent use in the selection procedure. Molecular techniques help in the utilization of genetic variability in breeding population. At the same time livestock genomes play important role in human genomics and their role for understanding human genomics cannot be overlooked. Recently, in the epigenetic and transcriptomic studies, RNA sequencing as a part of next generation sequencing has revolutionized the approach and ongoing trends of analysis. Keeping in mind the goals, these molecular techniques can be implemented successfully by following well defined, crisp and integrated strategy.

        Antibodies are used for preventing several infectious diseases in food animals. Though, antibiotics can deal with infection however, their widespread usage may cause developments of resistance and can also get transferred to humans through animal products. Therefore, production of antibodies against infectious agents in the egg yolk could be an interesting alternative. The present study was conducted with a focus on producing the antibody against Escherichia coli E68 and H28 in egg yolk of laying hens, which are believed to be a cause for diarrhea and beriberi in piglets. The result received from the experiment were promising and have shown efficiency of antibody production in the range of 2-7.3% in the groups which are infected with E68 only and the one which was infected with both strains. The outcome of present research has revealed the potentiality of egg yolk in production of antibody for laying hens, could open a new approach for production of antibodies to manage diarrhea and beriberi

        Osteosarcoma (OS) is one of the most common malignant primary bone tumors and NF-κB appears to play a causative role, but the mechanisms are poorly understood. OS is one of the pleomorphic, highly metastasized and invasive neoplasm which is capable to generate osteoid, osteoclast and osteoblast matrix. Its high incidence has been reported in adolescent and children. Cell signal cascade is the pivotal functional mechanism acquired during the differentiation, proliferation, growth and survival of the cells in neoplasm including OS. The major limitation to the success of chemotherapy in OS is the development of multidrug resistance (MDR). Answers to all such queries might come from the knock-in experiments in which the combined approach of miRNAs with NF-κB pathway is put into use. Abnormal miRNAs can modulate several epigenetical switching as a hallmark of number of diseases via different cell signaling. Studies on miRNAs have opened up the new avenues for both the diagnosis and treatment of cancers including OS. Collectively, through the present study an attempt has been made to establish a new systematic approach for the investigation of microRNAs, biophysiological factors and their target pairs with NF-κB to ameliorate oncogenesis with the “bridge between miRNAs and NF- κB”. The application of NF-κB inhibitors in combination with miRNAs is expected to result in a more efficient killing of the cancer stem cells and a slower or less likely recurrence of cancer.

        Mesenchymal stem cells (MSCs) are considered to be attractive approaching in gene or drug delivery for cancer therapeutic strategies. In this study, the ability and feasibility of human bone marrow derived MSCs expressing the cytosine deaminase (CD)/5-Fluorocytosin (5-FC) prodrug was evaluated to target human osteosarcoma cell line Cal-72. At first, the fibroblast-like cells were successfully obtained from human bone marrow and demonstrated that they contained full of stem characteristics by the ability of differentiation into adipocyte/osteocyte and expression of typical mesenchymal markers CD90, CD44, while negative for CD34 and CD133 markers. We established the stable CD-expressing MSCs cell line (CD-MSCs) by transfection of pEGFP-C3 containing cytosine deaminase::uracil phos-phoribosyltransferase (CD::UPRT) gene into MSCs, and confirmed that the manipulated MSCs still remained full characteristics of multipotent cells and shown migration toward human osteosarcoma cancer cells Cal-72 as high as origin MSCs. Based on bystander effect, the therapeutic CD-MSCs significantly augmented the cytotoxicity on cancer cell Cal72 in either direct co-culture or conditioned medium in the presence of 5-FC. Moreover, in osteosarcoma cancer- bearing mice, the therapeutic CD/5-FC MSCs showed the inhibition of tumor growth compared with control mice which was s.c injected with only Cal72. Our findings suggest that these therapeutic CD-MSCs may be suitable and viable cellular vehicles for targeting human osteosarcoma cancer.
