High rates of tenofovir failure in a CRF01_AE-predominant HIV epidemic in the Philippines

The Philippines has the fastest growing HIV epidemic in the Asia-Pacific. This increase was accompanied by a shift in the predominant HIV subtype from B to CRF01_AE. Increasing evidence points to a difference in treatment responses between subtypes. We examined treatment failure and acquired drug resistance (ADR) in people living with HIV (PLHIVs) after one year on antiretrovirals (ARVs).

Response to the 09 June 2021 statement of Dr. Maximilian Larena and Prof. Mattias Jakobson on the conduct of their Genomic Study on the Filipino Past

Since the Philippine Genome Center is mentioned and we have received numerous queries from colleagues in the country and the region, we are compelled to issue this Statement to address the following:
– the possible inference (from the way the Statement is written) that the head of the Philippine Genome Center’s (PGC) Program on Forensics and Ethnicity connived with the National Commission on Indigenous Peoples (NCIP) and Philippine Health Ethics Research Board (PHREB) against Dr. Larena and Prof. Jakobsson’s research or is responsible for their actions; and
– the imputation that the ethical issues raised by these agencies and PGC aim to discredit “good research” because the head of PGC’s Program on Forensics and Ethnicity is pursuing similar genetic research.

PGC Mindanao engages in a collaborative SARS-COV-2 genomics study using a portable sequencing platform

The Oxford Nanopore MinION is a portable sequencer and has the lowest instrument cost among all sequencing platforms with a 97.5 to >99.3% raw read accuracy (Oxford Nanopore Technologies, 2021). The technology has demonstrated its utility for sequencing biological entities, from the simple nano-sized viruses to complex plants and animals, generating sequence information that is sufficient to provide comprehensive insights into the underlying genome architecture. It has also been validated to produce SARS-CoV-2 consensus sequences with the same accuracy as other sequencing platforms (Bull et al., 2020 and Charre et al., 2020).

High Performance Computing and Data Science Workflow in Julia

HPC and Data Science Workflow in Julia #PGCTalks Date: July 16, 2021, Friday, 4:30-6:00pm This webinar is open to the public and registration is free. Abstract Julia is specifically designed from the start of its conception as a language for high-performance computation but at the same time highly interactive. To achieve this, Julia is one […]

Genetic Structure and Diversity of Banana Bunchy Top Virus (BBTV) in the Philippines

Banana bunchy top virus (BBTV) is an important disease of banana in the Philippines and in other banana-producing countries. This study was conducted to investigate the genetic structure and diversity of Philippine BBTV isolates which remain unexplored in the country. BBTV-infected plant tissues were sampled from banana-growing provinces (i.e., Cagayan, Isabela, Quirino, Batangas, Laguna, Rizal, Quezon, Palawan, Cebu, Leyte, and Davao del Sur) and the partial DNA-R gene of BBTV was sequenced.

Detection and Genome Sequencing of SARS-CoV-2 Variants Belonging to the B.1.1.7 Lineage in the Philippines

Coronavirus disease 2019 (COVID-19) is an infectious disease that has gained pandemic status from the World Health Organization, with millions of cases and deaths recorded worldwide. This global health crisis is caused by the virus referred to as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a member of the genus Betacoronavirus (Coronaviridae), together with the causative agents of the first SARS outbreak in 2003 and the Middle East respiratory syndrome (MERS) in 2012.

PGC SARS-CoV-2 Bulletin No. 7: Detection and characterization of a new SARS-CoV-2 lineage P.3, with spike protein mutations E484K, N501Y, P681H and LGV 141-143 deletion, from samples sequenced through the intensified UP-PGC, UP-NIH and DOH biosurveillance program

A close examination of the mutation profile of the P.3 viruses revealed that apart from E484K and N501Y, they also share other spike protein mutations that are likely to have functional significance (Figure 2). This includes the P681H mutation, also found in lineage B.1.1.7 viruses, as well as a three-amino acid deletion at positions 141 to 143 (LGV141_143del).
