Title : The future of pharmacogenetic polymorphism, pharmacogenomics and pharmamicrobiome in cancer treatment
Abstract:
Drug metabolism is crucial in any functioning of a drug, particularly in drugs for cancer treatment. Several drugs do not function in human body in their original state unless metabolised to its required functioning metabolite to affect its target organ/site or tissue. Drug metabolism occurs via certain drug metabolising enzymes and transporters which are responsible for drug biotransformation and function. The increasing understanding of the implications of genetic variation, genomics, and microbes in disease, is paramount in identifying and validating clinically relevant biomarkers to improve patient outcomes during chemotherapy.
The human genome has variation occurring in every 300-1000 nucleotides, with over 14 million single nucleotide polymorphisms (SNPs) across the entire genome. The individual differences in traits, characteristics and behaviour can determine patients’ response administered with same drug.
Conclusion: To reduce toxicity and improve efficiency of therapy, it is crucial to understand variations in genetics and genomic that impacts on drug response, to optimize cancer therapy and individual side effects. Researchers have intensely focused on human genomes and genetics; understanding the roles of microbiome in drug metabolism and function, could further define patient’s response to therapy?
