Chromosome duplication causing gene‐dosage‐based effects on the gene expression level in Gossypium hirsutum‐Gossypium australe addition lines

Plant Direct, 2020
Polyploidization, or whole‐genome duplication, leads to gene expression changes that drive the evolution of many plants and some animals. However, the role of the dosage effect on gene expression changes following genome duplication remains unclear. Here,

Gene dosage and the evolution of gene expression [PDF]

, 2016
The duplication and loss of genes, chromosomes and whole genomes has had a major impact on the evolution of most organisms. Changes in gene copy number, called gene dosage, may influence the resulting level of gene product through changes in gene ...

Dimethyl fumarate combined with cisplatin at subcytotoxic doses sensitizes cervical cancer toward ferroptosis and apoptosis through GSH restriction and p53 (re)activation

Molecular Oncology, EarlyView.
Dimethyl fumarate (DMF) reduces growth of HPV‐positive cervical cancer spheroids and induces ferroptosis in cervical cancer cells via blocking SLC7A11/Glutathione (GSH) axis. Combination of subcytotoxic doses of DMF and cisplatin (CDDP) further suppresses spheroid growth and drives cell death in 2D culture models.

Condensin-mediated chromosome organization and gene regulation

Frontiers in Genetics, 2015
In many organisms sexual fate is determined by a chromosome-based method which entails a difference in sex chromosome-linked gene dosage. Consequently, a gene regulatory mechanism called dosage compensation equalizes X-linked gene expression between the ...

Heteroduplex Formation in SMN Gene Dosage Analysis [PDF]

The Journal of Molecular Diagnostics, 2001
Most spinal muscular atrophy patients lack both copies of SMN1 exon 7 and most carriers have only one copy of SMN1 exon 7. We investigated the effect of SMN1/SMN2 heteroduplex formation on SMN gene dosage analysis, which is an assay to determine copy number of SMN1 exon 7 that utilizes multiplex quantitative polymerase chain reaction (PCR) with DraI ...

Retinal gene therapy in patients with choroideremia: initial findings from a phase 1/2 clinical trial

, 2014
Background: Choroideremia is an X-linked recessive disease that leads to blindness due to mutations in the CHM gene, which encodes the Rab escort protein 1 (REP1).

Bidirectional transcription of a novel chimeric gene mapping to mouse chromosome Yq [PDF]

, 2007
Background The male-specific region of the mouse Y chromosome long arm (MSYq) contains three known highly multi-copy X-Y homologous gene families, Ssty1/2, Sly and Asty.

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

Molecular Oncology, EarlyView.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated

Engineered extracellular vesicles enriched with the miR‐214/199a cluster enhance the efficacy of chemotherapy in ovarian cancer

Molecular Oncology, EarlyView.
Loss of the miR‐214/199a cluster is associated with recurrence in ovarian cancer. Engineered small extracellular vesicles (m214‐sEVs) elevate miR‐214‐3p/miR‐199a‐5p in tumor cells, suppress β‐catenin, TLR4, and YKT6 signaling, reprogram tumor‐derived sEV cargo, reduce chemoresistance and migration, and enhance carboplatin efficacy and survival in ...
