Optimized Signal Peptide for Secretory Expression of Human Recombinant Somatropin in .

The human somatropin is a single-chain polypeptide with a pivotal role in various biological processes. Although is considered as a preferred host for the production of human somatropin, the high expression of this protein in results in the accumulation of protein as inclusion bodies. Periplasmic expression using signal peptides could be used to overcome the formation of inclusion bodies; still, the efficiency of each of the signal peptides in periplasmic transportation is varied and often is protein specific.

The Role of Interferons in Long Covid Infection.

Although the new generation of vaccines and anti-COVID-19 treatment regimens facilitated the management of acute COVID-19 infections, concerns about post-COVID-19 syndrome or Long Covid are rising. This issue can increase the incidence and morbidity of diseases such as diabetes, and cardiovascular, and lung infections, especially among patients suffering from neurodegenerative disease, cardiac arrhythmias, and ischemia. There are numerous risk factors that cause COVID-19 patients to experience post-COVID-19 syndrome.

Epigenetic insights in the diagnosis, prognosis, and treatment selection in CRC, an updated review.

Background/aim: The gradual accumulation of genetic and epigenetic alterations can lead to the development of colorectal cancer. In the last decade much research has been done to discover how methylation as an epigenetic alteration leads to carcinogenesis. While Methylation is a biological process, it can influence gene expression by affecting the promoter activity.
