Summary
Highlights
Dr. Ian Kenrich Pontanilla, a UP scientist and head of the DNA Barcoding Laboratory in UP Diliman, introduces himself and the topic of bioinformatics and digital science information in the Philippine context. He specializes in evolutionary biology, molecular phylogenetics, and wildlife forensics, and his lab works on DNA barcoding for Philippine endemic species and environmental DNA methods.
Dr. Pontanilla explains that DNA is the genetic material containing instructions for all living organisms. He differentiates between prokaryotic and eukaryotic cells, explaining where DNA is stored. He then details the structure of nucleic acids (DNA and RNA), their nucleotide components (sugar, phosphate, nitrogenous bases: purines and pyrimidines), and how they form chains and double strands.
The central dogma describes the flow of genetic information: DNA replicates, transcribes to RNA, and RNA translates to proteins. He explains DNA replication, transcription (forming various RNA types), and translation (mRNA used as a template for protein synthesis). He also mentions reverse transcription, as seen in viruses like COVID and HIV, where RNA is converted back to DNA.
Genetic information is stored in DNA as sequences of nucleotides, which dictate traits and functions. He introduces 'omics' terms: genome (total DNA), transcriptome (total RNA), and proteome (total proteins). These sequence data, along with observational, taxonomic, ecological, and behavioral data, form a comprehensive view of genetic resources. He emphasizes the need for bioinformaticians to analyze the vast amounts of generated data.
Dr. Pontanilla provides examples of how genetic information is used: DNA barcoding for species identification (e.g., confirming ingredients in food, identifying endangered species), developing testing kits (e.g., for COVID, HIV, dengue), and genetically modified organisms (GMOs) like BT corn and BT eggplant. He also discusses synthetic biology, citing the conotoxin from the Conus geographicus snail as a source for potent painkillers.
He explains Access and Benefit Sharing (ABS), which mandates that countries have sovereign rights over their genetic resources. Users must obtain prior informed consent and share benefits derived from these resources with the providing country, especially the community where the product originated. This prevents exploitation of local biodiversity by foreign entities.
In the Philippines, the collection of genetic resources is governed by Republic Act 9147 (Wildlife Resources Conservation and Protection Act). Researchers need MOAs or AOUs with relevant government agencies (DENR, DA-BFAR, Palawan Council for Sustainable Development) and prior informed consent from local government units and indigenous peoples. Challenges include limited capital for local biotechnology, high costs of reagents and equipment, a shortage of bioinformaticians, long gestation periods for R&D, and the threatened status of many endemic species.
The Philippines is a biodiversity hotspot with a high concentration of endemic species, many of which are threatened. There is no comprehensive national database for Philippine Digital Sequence Information (DSI), with data scattered across global repositories. Some DSI are embargoed or have restricted access due to patent applications, often by foreign entities, leading to unfair advantages for countries without such restrictions.
During the Q&A, Dr. Pontanilla discusses the salary range for bioinformaticians in the Philippines (starting around PHP 50,000+). He addresses the possibility of resurrecting extinct animals, noting the complexity beyond just DNA, as environmental context is crucial. He expresses hope for the Philippines to become a leader in biotechnology but emphasizes the need for government investment in science and technology alongside innovation from local scientists and industry.
He highlights the current educational crisis in the Philippines, particularly in science education, and the need to review curricula and integrate science and technology. He also discusses genetic screening, mentioning the newborn screening program in the Philippines and the ethical considerations surrounding the use and potential exploitation of personal genetic information, urging caution about the future implications of such data in society.
