Abstract

In this study, we isolated the simian betaretrovirus serotype-2 (SRV-2) reverse transcriptase (RT) gene from infected Indonesian cynomolgus monkey (Macaca fascicularis). The gene was then cloned in Escherichia coli expression system. The SRV-2 RT gene is located between nucleotides 3284-4925 in the polyprotein (Pol) region encodes 547 amino acids. Analysis of expression using SDS-PAGE and western blot techniques showed a specific band of 64.9 kDa, indicating SRV-2 RT recombinant enzyme. Purification of SRV-2 RT recombinant enzyme produced 312 μg mL-1 protein with 7.1 U μL-1 enzyme activities. Application of this recombinant enzyme in reverse transcription-PCR (RT-PCR) of β-globin and β-actin genes produced DNA fragments of 206 and 350 bp, indicating amplification of β-globin and β-actin genes, respectively. Therefore, the expressed SRV-2 RT enzyme was proven to be functional, although the activity was low.

Abstract

Various therapeutic agents have been used to treat stroke. However, currently there is extensive exploration of new potential therapies for stroke involving novel signaling pathways and development of therapeutic agents through biotechnological approaches. This article examines the recent advances in stroke therapy using biotechnology-based drugs. We conducted a comprehensive search using specific keywords relating to Ischemic Stroke, ATMP, Peptide, Antibody, Stem Cells, and connected topics in the databases of Medline, Scopus, Web of Science, and Pubmed. The main focus of the selection criteria was on English-language literature that explored the relationship between Ischemic Stroke, ATMP, Peptide, Antibody, Stem Cells, and related factors. This article exhibits that numerous studies are being conducted and have demonstrated the use of biotechnology-based therapeutic agents for stroke, including tissue plasminogen activators, therapeutic peptides, microRNA, monoclonal antibodies, as well as stem cells. These therapeutic agents have not only been tested on test animals but have also been commenced to be tested in clinical studies or have obtained marketing approval for use in ischemic stroke patients. In conclusion, despite the limited number of approved drugs, advancements in biotechnology are poised to make them common adjunct treatments for stroke patients, not just for managing the disease but also for its cure and regenerative effects in survivors.
