Site-Specific Incorporation of Unnatural Amino Acids into Escherichia coli Recombinant Protein: Methodology Development and Recent Achievement

Biomolecules, 2019
More than two decades ago a general method to genetically encode noncanonical or unnatural amino acids (NAAs) with diverse physical, chemical, or biological properties in bacteria, yeast, animals and mammalian cells was developed. More than 200 NAAs have

Expanding Genetic Code to Generate Human Brain Organoids with Both Vasculature and Microglia‐Like Cells

Advanced Science, EarlyView.
Using genetic code expansion, we engineered vascularized human cerebral organoids (vhCOs) with microglia‐like cells and blood‐brain barrier features. vhCOs recapitulate neurovascular interactions, regional identities, and neuronal subtypes resembling the fetal brain.

Extrachromosomal psi+ determinant suppresses nonsense mutations in yeast [PDF]

Journal of Bacteriology, 1979
The extrachromosomal psi+ determinant in the yeast Saccharomyces cerevisiae enhanced the expression of Mendelian UAA suppressors by 6- to 10-fold. The psi+ determinant by itself is a weak UAA suppressor that caused the production of approximately 1% of the normal level of iso-1-cytochrome c in a strain containing the UAA mutation cycl-72.

Transcription Factors Mcm1 and Sfp1 May Affect [PSI⁺] Prion Phenotype by Altering the Expression of the SUP35 Gene

Microbiology Research
Mcm1 is an essential Q/N-rich transcription factor. Q/N-rich proteins interact with each other, and many affect the [PSI+] prion formed by the translation termination factor Sup35 (eRF3).

TNAP and PHOSPHO1 Function Synergistically to Afford Critical Control Over the Mineralization of the Postnatal Murine Skeleton

Advanced Science, EarlyView.
Biomineralization underpins skeletal development, yet its molecular control remains incompletely understood. Using a novel murine knockout model, this study reveals the essential and complementary roles of PHOSPHO1 and TNAP in postnatal skeletal development.

Genetic Basis of Non-Syndromic Childhood Glaucoma Associated with Anterior Segment Dysgenesis: A Narrative Review

Pharmaceuticals
Twenty causative genes have been reported that cause non-syndromic childhood glaucoma associated with anterior segment dysgenesis. FOXC1, PAX6 and PITX2 are the most well-known, but cases linked to SLC4A11, PITX3 and SOX11 have also been reported.

Advances in therapeutic use of a drug-stimulated translational readthrough of premature termination codons

Molecular Medicine, 2018
Premature termination codons (PTCs) in the coding regions of mRNA lead to the incorrect termination of translation and generation of non-functional, truncated proteins.

CRISPR and Gene Augmentation Rescue Trabecular Meshwork Dysfunction in iPSC Models of Lowe Syndrome

Advanced Science, EarlyView.
By modeling Lowe syndrome using patient‐derived iPSCs, this study establishes a human disease model that faithfully recapitulates OCRL deficiency‐associated ciliary and cytoskeletal defects. The model enables evaluation of both mutation‐agnostic DNA augmentation and CRISPR‐mediated mutation correction strategies, both of which restore OCRL function and

UPF1, a conserved nonsense-mediated mRNA decay factor, regulates cyst wall protein transcripts in Giardia lamblia. [PDF]

PLoS ONE, 2008
The Giardia lamblia cyst wall is required for survival outside the host and infection. Three cyst wall protein (cwp) genes identified to date are highly up-regulated during encystation. However, little is known of the molecular mechanisms governing their

A Robust Deep Temporal Causal Discovery Platform for Single‐Cell Gene Regulatory Network Reconstruction

Advanced Intelligent Discovery, EarlyView.
scTIGER2.0 is a deep‐learning framework that infers gene regulatory networks from single‐cell RNA sequencing data. By integrating correlation, pseudotime ordering, deep learning and bootstrap‐based significance testing, it reduces false positives and reveals directional gene interactions.
