Multi-locus assortment (MLA) for transgene dispersal and elimination in mosquito populations. [PDF]

open access: yesPLoS ONE, 2009
BACKGROUND:Replacement of wild-type mosquito populations with genetically modified versions is being explored as a potential strategy to control vector-borne diseases.

Nucleotide mismatches prevent intrinsic self-silencing of hpRNA transgenes to enhance RNAi stability in plants

open access: yesNature Communications, 2022
Long hairpin RNA (hpRNA) transgenes are the most widely used RNAi technology in plants, but are potentially subject to self-induced transcriptional silencing.

Contrasting epigenetic control of transgenes and endogenous genes promotes post-transcriptional transgene silencing in Arabidopsis

open access: yesNature Communications, 2021
Accumulating evidences point to a discrepancy in the epigenetic behaviour of transgenes and endogenous genes. Here, via characterization of mutants impaired in histone demethylases JMJ14 and IBM1, the authors show that transgenes and endogenous genes are

Measurement of Transgenes Copy Number in Wheat Plants Using Droplet Digital PCR

open access: yesBio-Protocol, 2022
Genetic transformation is a powerful method for the investigation of gene function and improvement of crop plants. The transgenes copy number in the transgenic line is involved in gene expression level and phenotypes.

Synthetic mammalian transgene negative autoregulation

open access: yesMolecular Systems Biology, 2013
Biological networks contain overrepresented small‐scale topologies, typically called motifs. A frequently appearing motif is the transcriptional negative‐feedback loop, where a gene product represses its own transcription.

Matrix metalloproteinase-20 over-expression is detrimental to enamel development: a Mus musculus model. [PDF]

open access: yesPLoS ONE, 2014
Matrix metalloproteinase-20 (Mmp20) ablated mice have enamel that is thin and soft with an abnormal rod pattern that abrades from the underlying dentin.

Strategies for delivery of CRISPR/Cas-mediated genome editing to obtain edited plants directly without transgene integration

open access: yesFrontiers in Genome Editing, 2023
Increased understanding of plant genetics and the development of powerful and easier-to-use gene editing tools over the past century have revolutionized humankind’s ability to deliver precise genotypes in crops.

New approaches for characterization of the genetic stability of vaccine cell lines

open access: yesHuman Vaccines & Immunotherapeutics, 2017
The genetic stability of cell lines is a critical analytical attribute required to demonstrate the quality of cells over time. During cell passage, mutations can arise in the genomic DNA, potentially leading to changes in the final vaccine product.

Chromosome-wide mechanisms to decouple gene expression from gene dose during sex-chromosome evolution

open access: yeseLife, 2016
Changes in chromosome number impair fitness by disrupting the balance of gene expression. Here we analyze mechanisms to compensate for changes in gene dose that accompanied the evolution of sex chromosomes from autosomes.

Combined transgene immortalized urothelial cells capable of reprogramming and hepatic differentiation

open access: yesBiochemistry and Biophysics Reports, 2022
Human primary cells, including urine-derived cells (UCs), are an excellent source for generation of pluripotent stem cells (iPSCs) to model disease. However, replicative senescence starts early and shortens the time window for generation of iPSCs.
