Circadian Disruption Primes Myofibroblasts for Accelerated Activation as a Mechanism Underpinning Fibrotic Progression in Non-Alcoholic Fatty Liver Disease

Cells 12, no. 12: 1582. doi: 10.3390/cells12121582

This work examined the impact of circadian rhythm disruption on the activation of hepatic stellate cells, showing that this leads to a primed state that worsens fibrotic injury in mice. We leveraged the genes that had altered expression in this primed state as potential biomarkers, using the ID LIVER cohort to show elevated levels of AOC3 in patients with evidence of fibrosis or high risk of liver disease.

SOX9 is required for kidney fibrosis and regulates NAV3 to control renal myofibroblast function in mice and humans

Sci Signal . 2021 Mar 2;14(672):eabb4282. doi: 10.1126/scisignal.abb4282.

This study explored the role of SOX9 in kidney fibrosis using the unilateral ureteral obstruction model with or without repression of SOX9 expression, demonstrating that markers of fibrosis are significantly reduced in the absence of SOX9. RNAseq and relative gene expression analyses identified Neural Navigator 3 (NAV3) as a novel, SOX9-dependent marker of fibrosis. Inhibiting Nav3 in cultured kidney pericytes and HEK fibroblasts impaired migration, cytoskeletal stability and mechanotransduction.

Transcriptional upregulation of Bag3, a chaperone-assisted selective autophagy factor, in animal models of KY-deficient hereditary myopathy

Elliot J. Jokl, Gideon L. Hughes, Tobias Cracknell, Mary E. Pownall, Gonzalo Blanco

Disease Models & Mechanisms 2018 11: dmm033225 doi: 10.1242/dmm.033225 Published 6 July 2018

In this paper, based on my PhD project, we showed that the absence of the cytoskeletal protein KY results in the apparent upregulation of the chaperone BAG3. In this project I generated in vitro myoblast and in vivo zebrafish models of KY deficiency using CRISPR/Cas9 and explored common hallmarks with the established ky/ky mouse model. My work suggests that the absence of KY leads to a baseline of elevated cell stress and a failure to further upregulate this in response to mechanical stimulation.

Disrupted autophagy undermines skeletal muscle adaptation and integrity

Elliot J. Jokl and Gonzalo Blanco

Mamm Genome. 2016; doi: 10.1007/s00335-016-9659-2 Published online 2 Aug 2016

This review explored the critical role of autophagy in skeletal muscle and the myopathies resulting from mutations or disruption to autophagy components.
