Abstract

HD disease is a common cause of neonatal intestinal obstruction. HD disease is a congenital disorder of the colon characterized by the absence of parasympathetic ganglion cells in the sub mucosal plexus of Meissneri and the mienterikus plexus of Auerbachi. Objective: To design specific primers for amplification of exon 5 in EDNRB gene and test the specificity in silico. To determine the optimum PCR conditions for amplification of exon 5 in EDNRB gene. Methods This type of research is descriptive. The purpose of descriptive research is to provide an overview or description of the EDNRB exon 5 gene primer design and PCR optimization. Electrophoresis results showed the temperature of 56 oC is the right temperature characterized by a single band and looks the thickest and brightest with the appropriate amplicons size of 367 bp, The results for the EDNRB gene primer exon 5 obtained the optimum concentration of 0.8 µM. This is characterized by DNA bands that look clear and thickest. The specific sequence of forward primer is 5'ATTTCA GAGACG GGAAG TGG3' reverse primer is 5'GGCACT CACTCATCATCTTG 3' which produces amplicons with a length of 367 bp. The optimum annealing temperature is 56 oC and the optimum primer concentration is 0.8 µM.

Abstract

Long bean (Vigna sinensis) is a plant from the Leguminosae family, which has an important role in the Indonesian economy because it is widely consumed as food. The purpose of this research is to utilize mutation technology in supporting plant breeding to produce superior long bean varieties. The research method carried out was a non-factorial Randomized Group Design (RAK), namely soaking the seeds of long bean plants with colchicine to see the effect of colchicine treatment on chromosomal mutations in long bean plants. The results showed significant differences between colchicine concentrations of 0.02% and 0.03%. At a concentration of 0.02%, the cell nucleus appeared solid red and in the center of the cell, but the number and shape of chromosomes were not clearly visible. This concentration is not optimal for inducing polyploidy. Meanwhile, at a concentration of 0.03%, the chromosomes were more clearly visible than the previous concentration.

Abstract

Hirschsprung’s disease is a congenital condition characterized by a failure of nerve function along the gastrointestinal (GI) tract, resulting in the absence of enteric ganglia in the most distal segment of the colon. Although the prevalence rate is 1:5000 babies born, Hirschsprung’s disease can have a significant impact on patients, especially in terms of quality of life. One of the main genetic factors often associated with the etiopathogenesis of Hirschsprung’s disease is the RET gene. This study aims to provide scientific insight into advances in the understanding of genetic variants associated with RET gene mutations and their role in causing Hirschsprung disease. The research design used was literature review, articles were collected based on sources derived from Google Scholar, PubMed, and EMBASE which included national and international journals published in the last 10 years. Based on the articles collected, it was found that the RET gene is essential for the growth, migration, and maturation of precursor cells into functional neurons. Mutations in the RET gene can interfere with the normal formation and function of nerve cells, leading to symptoms typical of Hirschsprung’s disease.
