Exploiting metabolic adaptations to overcome dabrafenib treatment resistance in melanoma cells

Molecular Oncology, EarlyView.
We show that dabrafenib‐resistant melanoma cells undergo mitochondrial remodeling, leading to elevated respiration and ROS production balanced by stronger antioxidant defenses. This altered redox state promotes survival despite mitochondrial damage but renders resistant cells highly vulnerable to ROS‐inducing compounds such as PEITC, highlighting redox

Systems biology investigation of cAMP modulation to increase SMN levels for the treatment of spinal muscular atrophy. [PDF]

PLoS ONE, 2014
Spinal muscular atrophy (SMA), a leading genetic cause of infant death worldwide, is an autosomal recessive disorder caused by the loss of SMN1 (survival motor neuron 1), which encodes the protein SMN.

Dammarenediol II enhances etoposide‐induced apoptosis by targeting O‐GlcNAc transferase and Akt/GSK3β/mTOR signaling in liver cancer

Molecular Oncology, EarlyView.
Etoposide induces DNA damage, activating p53‐dependent apoptosis via caspase‐3/7, which cleaves PARP1. Dammarenediol II enhances this apoptotic pathway by suppressing O‐GlcNAc transferase activity, further decreasing O‐GlcNAcylation. The reduction in O‐GlcNAc levels boosts p53‐driven apoptosis and influences the Akt/GSK3β/mTOR signaling pathway ...

DJ-1 knockout augments disease severity and shortens survival in a mouse model of ALS. [PDF]

PLoS ONE, 2015
Amyotrophic lateral sclerosis (ALS) is a progressive, lethal, neurodegenerative disorder, characterized by the degeneration of motor neurons. Oxidative stress plays a central role in the disease progression, in concert with an enhanced glutamate ...

FUS mutant human motoneurons display altered transcriptome and microRNA pathways with implications for ALS pathogenesis [PDF]

, 2017
The FUS gene has been linked to amyotrophic lateral sclerosis (ALS). FUS is a ubiquitous RNA-binding protein, and the mechanisms leading to selective motoneuron loss downstream of ALS-linked mutations are largely unknown.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

The contribution of mouse models to understanding the pathogenesis of spinal muscular atrophy

Disease Models & Mechanisms, 2011
Spinal muscular atrophy (SMA), which is caused by inactivating mutations in the survival motor neuron 1 (SMN1) gene, is characterized by loss of lower motor neurons in the spinal cord. The gene encoding SMN is very highly conserved in evolution, allowing

RaMBat: Accurate identification of medulloblastoma subtypes from diverse data sources with severe batch effects

Molecular Oncology, EarlyView.
To integrate multiple transcriptomics data with severe batch effects for identifying MB subtypes, we developed a novel and accurate computational method named RaMBat, which leveraged subtype‐specific gene expression ranking information instead of absolute gene expression levels to address batch effects of diverse data sources.

Clinical research advance of therapeutic strategies for spinal muscular atrophy

Chinese Journal of Contemporary Neurology and Neurosurgery, 2019
Spinal muscular atrophy (SMA) is an autosomal recessive neuromuscular disease characterized by progressive muscular weakness and atrophy caused by degeneration of brain stem and spinal cord motor neurons. SMA is common genetic neuromuscular disorder that

Survival motor neuron deficiency enhances progression in an amyotrophic lateral sclerosis mouse model

Neurobiology of Disease, 2009
Mutations in the ubiquitously expressed survival motor neuron 1 (SMN1) and superoxide dismutase 1 (SOD1) genes are selectively lethal to motor neurons in spinal muscular atrophy (SMA) and familial amyotrophic lateral sclerosis (ALS), respectively ...
