Cortistatin and somatostatin are neuropeptides which have inhibitory effects on growth hormone through common five receptors. Although, both have inhibitory effects but, only cortistatin has direct inhibitory effects on growth hormone secretagogue and is more potent inhibitor of growth hormone than somatostatin. This control of growth hormone can be manipulated through immunoneutralization of cortistatin through cortistatin DNA vaccine rather than antibodies application. A DNA vaccine of cortistatin can be produced using recombinant DNA technology in a eukaryotic expression system and will serve as a tool not to only alleviate the growth hormone deficiency problems in human but, can also be used to improve growth rate in farm animals.

Growth hormone (GH)-releasing hormone (GHRH), a hypothalamic peptide initially characterized for its role in GH regulation, has gained increasing attention due to its GH-independent action on peripheral physiology, including that of the cardiovascular system. While its effects on the peripheral vasculature are still under investigation, GHRH and synthetic agonists have exhibited remarkable receptor-mediated cardioprotective properties in preclinical models. GHRH and its analogs enhance myocardial function by improving contractility, reducing oxidative stress, inflammation, and offsetting pathological remodeling.

The principle of the "growth-defense trade-off" governs how plants adjust their growth and defensive strategies in response to external factors, impacting interactions among plants, herbivorous insects, and their natural enemies. Mineral nutrients are crucial in modulating plant growth and development through their bottom-up effects. Emerging evidence has revealed complex regulatory networks that link mineral nutrients to plant defense responses, influencing the delicate balance between growth and defense against herbivores.

In recent years a number of adverse effects have been observed to be associated with this therapy, the most notable of which is hyperglycemia. A literature search was conducted to include case studies, case series, systematic reviews, and meta-analyses within the last 10 years that evaluated patients with mutated hormone receptor-positive, human epidermal growth factor receptor 2 negative metastatic breast cancer.

Drought is a major abiotic stress in restricting the growth, development, and yield of maize. As a significant epigenetic regulator, small RNA also functions in connecting the transcriptional and post-transcriptional regulatory network. Further to help comprehending the molecular mechanisms underlying drought adaptability and tolerance of maize, an integrated multi-omics analysis of transcriptome, sRNAome, and degradome was performed on the seedling roots of an elite hybrid Zhengdan958 under drought stress.
