Novel bioactive natural products from bacteria via bioprospecting, genome mining and metabolic engineering

open access: yesMicrobial Biotechnology, 2019
For over seven decades, bacteria served as a valuable source of bioactive natural products some of which were eventually developed into drugs to treat infections, cancer and immune system‐related diseases.

Construction of Large‐Scale Bioengineered Hair Germs and In Vivo Transplantation

open access: yesAdvanced Science, Volume 12, Issue 16, April 24, 2025.
Here, a novel bioengineered hair germ (BHG) system is developed using thermodynamically incompatible mucopolysaccharides for efficient hair follicle regeneration. The BHG microspheres, produced via microfluidic technology, encapsulate Wnt3a for sustained release, enhancing mesenchymal stem cell differentiation and activating key regeneration pathways ...

Redesigning pattern mining algorithms for supercomputers [PDF]

open access: yesarXiv, 2015
Upcoming many core processors are expected to employ a distributed memory architecture similar to currently available supercomputers, but parallel pattern mining algorithms amenable to the architecture are not comprehensively studied. We present a novel closed pattern mining algorithm with a well-engineered communication protocol, and generalize it to ...

An Engineered PfAgo with Wide Catalytic Temperature Range and Substrate Spectrum

open access: yesAdvanced Science, EarlyView.
This work presents a strategy for engineering thermophilic Ago proteins to obtain wide catalytic temperature range and broad substrate spectrum. This strategy is applied to engineer PfAgo and TtdAgo, and the biochemical properties of the engineered PfAgo are systematically characterized. The study further elucidates the structural differences involved.

Characterizing Scales of Genetic Recombination and Antibiotic Resistance in Pathogenic Bacteria Using Topological Data Analysis

open access: yes, 2014
Pathogenic bacteria present a large disease burden on human health. Control of these pathogens is hampered by rampant lateral gene transfer, whereby pathogenic strains may acquire genes conferring resistance to common antibiotics. Here we introduce tools

Mining Functional Modules by Multiview-NMF of Phenome-Genome Association [PDF]

open access: yesarXiv, 2017
Background: Mining gene modules from genomic data is an important step to detect gene members of pathways or other relations such as protein-protein interactions. In this work, we explore the plausibility of detecting gene modules by factorizing gene-phenotype associations from a phenotype ontology rather than the conventionally used gene expression ...

Unveiling Salt Tolerance Mechanisms in Plants: Integrating the KANMB Machine Learning Model With Metabolomic and Transcriptomic Analysis

open access: yesAdvanced Science, EarlyView.
Salt stress endangers coastal cereal crops, requiring resilient crop solutions. This study employs machine learning (KANMB) to analyze multi‐omics data from halophyte Spartina alterniflora, revealing 226 salt‐stress biomarkers and linking them to tolerance pathways. The MYB gene SaMYB35 regulates flavonoid biosynthesis under salinity.
