Background: The detection of porcine DNA is critical to ensuring adherence to halal standards, particularly in food and pharmaceutical products. This study aimed to design and validate species-specific primers targeting the mitochondrial Cyt b gene of Sus scrofa for porcine DNA identification. Using in silico tools such as NCBI, Primer3Plus, SnapGene, Mega and NetPrimer, four primer pairs were designed and assessed for specificity and efficiency. Methodology: Laboratory validation involved PCR amplification and bi-directional Sanger sequencing. Findings: The findings demonstrated that primers 2F/2R and 3F/3R successfully amplified the target DNA, producing amplicons of 514 bp and 456 bp, respectively. The primers exhibited high specificity, with no amplification observed in non-target DNA samples, including chicken and beef. Sanger sequencing confirmed that the amplified products corresponded to the Cyt b gene sequence of Sus scrofa with 100 % similarity, as validated through BLAST analysis. This study presents an accurate and dependable molecular method for detecting porcine DNA, with valuable applications in halal authentication and molecular diagnostics. Contribution: The developed primers offer an effective tool for accurately identifying porcine-derived components, addressing the critical demand for species-specific DNA detection to support halal compliance.

The decision between probe-based and non-probe-based qPCR assays is crucial, influenced by diagnostic goals and sample characteristics. This review provides an in-depth evaluation of these two assay types, analyzing their principles, strengths, drawbacks, and applications. A thorough review of the literature, primarily sourced from PubMed, was undertaken to explore prominent assay systems, including TaqMan, KASP, rhAmp, HRM, and SYBR Green. Probe-based qPCR assays, exemplified by TaqMan and rhAmp, are distinguished by their high specificity, aptitude for multiplex analysis, and reduced risk of false positives, making them highly suitable for SNP genotyping and pathogen detection. However, their elevated costs and intricate design requirements remain significant challenges. Conversely, non-probe-based assays, such as SYBR Green and HRM, present cost-effective alternatives with straightforward designs. HRM, in particular, is effective in identifying genetic variations like SNPs with remarkable sensitivity. Nonetheless, these methods are susceptible to non-specific amplifications, requiring careful optimization to maintain reliability. The selection of a suitable qPCR assay depends on various factors, including precision, affordability, and multiplexing capabilities, with applications spanning infectious disease detection and genetic disorder analysis. This review emphasizes the indispensable role of qPCR in molecular diagnostics while showcasing recent technological advances that aim to mitigate existing constraints and enhance diagnostic precision and accessibility.

Parkinson's disease is a degenerative nervous system disorder caused by the death of dopamine-producing cells in the substantia nigra. Dopaminergic treatment could alleviate motor symptoms for a period. One of the effective dopaminergic medications for symptomatic relief was Levodopa and dopamine agonists. Clinically, Levodopa was always combined with Dopa Decarboxylase (DDC) inhibitors, which redirected Levodopa metabolism towards the COMT pathway, increasing its bioavailability in the central nervous system. The purpose of this article was to investigate the relationship between COMT and MAO-B gene polymorphisms and Levodopa in Parkinson's disease patients, starting by gathering literature on the association between COMT and MAO-B polymorphisms and Levodopa in Parkinson's disease patients using various databases. Reviewed literature revealed that the most frequent polymorphism in the COMT gene was rs4680. Some polymorphisms significantly impacted the treatment of Parkinson's disease patients. However, despite efforts to identify genetic factors influencing the risk of side effects or treatment ineffectiveness, the role of pharmacogenetics in Parkinson's disease has not been fully explored and lacks consistent clinical recommendations. Further research was needed to tailor treatment to individual polymorphisms so that pharmacogenomic approaches could be applied more consistently

Reliable clinical diagnosis of Single Nucleotide Polymorphisms (SNPs) is necessary for personalizing tamoxifen medication according to CYP2D6*10 genetic variations. Our research aimed to create a recombinant plasmid for external control material with a molecular size of 3812 bp. The recombinant plasmid was achieved by cloning an 838 bp gene insert of CYP2D6*10 rs1065852 into a 2974 bp pJET1.2 plasmid into Escherichia coli DH10B and selection on ampicillin agar medium. Isolated E. coli recombinants provided the plasmid molecules for analysis. Bi-directional sequencing and Real-Time PCR confirmed the presence of wild-type and mutant rs1065852 DNA fragments in the plasmid, namely homozygote CC and TT. The conclusion is that we have successfully introduced a novel recombinant plasmid developed by cloning the SNP rs1065852, which carries the 100C>T mutation, using pJET 1.2/blunt system, which could significantly enhance the accuracy of clinical SNP diagnostics for personalized medicine in breast cancer treatment.
