HCT116 colorectal liver metastases exacerbate muscle wasting in a mouse model for the study of colorectal cancer cachexia [RESEARCH ARTICLE]
ABSTRACT Colorectal cancer (CRC) is often accompanied by formation of liver metastases (LM) and skeletal muscle wasting, i.e. cachexia. Despite affecting the majority of CRC patients, cachexia remains underserved, understudied and uncured. Animal models for the study of CRC-induced cachexia, in particular models containing LM, are sparse; therefore, we aimed to characterize two new models of CRC cachexia. Male NSG mice were injected subcutaneously (HCT116) or intrasplenically (mHCT116) with human HCT116 CRC tumor cells to disseminate LM, whereas experimental controls received saline (n=5-8/group). Tumor growth was accompan...

Ablation of Bscl2/seipin in hepatocytes does not cause metabolic dysfunction in congenital generalised lipodystrophy [RESEARCH ARTICLE]
ABSTRACT Mutations affecting the BSCL2 gene cause the most severe form of congenital generalised lipodystrophy (CGL). Affected individuals develop severe metabolic complications including diabetes and hepatic steatosis. Bscl2-deficient mice almost entirely reproduce the CGL phenotype. Adipose tissue-specific loss of Bscl2 is also sufficient to cause early-onset generalised lipodystrophy in mice. However, these mice do not show severe metabolic dysfunction, even when challenged with a high-fat diet. Germline Bscl2 loss in mice and BSCL2 disruption in humans causes severe hepatic steatosis, and the encoded protein, seipin, h...

Addressing variability in iPSC-derived models of human disease: guidelines to promote reproducibility [REVIEW]
ABSTRACT Induced pluripotent stem cell (iPSC) technologies have provided in vitro models of inaccessible human cell types, yielding new insights into disease mechanisms especially for neurological disorders. However, without due consideration, the thousands of new human iPSC lines generated in the past decade will inevitably affect the reproducibility of iPSC-based experiments. Differences between donor individuals, genetic stability and experimental variability contribute to iPSC model variation by impacting differentiation potency, cellular heterogeneity, morphology, and transcript and protein abundance. Such effects wil...

Modelling the pathogenesis of X-linked distal hereditary motor neuropathy using patient-derived iPSCs [RESEARCH ARTICLE]
ABSTRACT ATP7A encodes a copper-transporting P-type ATPase and is one of 23 genes in which mutations produce distal hereditary motor neuropathy (dHMN), a group of diseases characterized by length-dependent axonal degeneration of motor neurons. We have generated induced pluripotent stem cell (iPSC)-derived motor neurons from a patient with the p.T994I ATP7A gene mutation as an in vitro model for X-linked dHMN (dHMNX). Patient motor neurons show a marked reduction of ATP7A protein levels in the soma when compared to control motor neurons and failed to upregulate expression of ATP7A under copper-loading conditions. These resu...

Absence of p.R50X Pygm read-through in McArdle disease cellular models [RESEARCH ARTICLE]
ABSTRACT McArdle disease is an autosomal recessive disorder caused by the absence of muscle glycogen phosphorylase, which leads to blocked muscle glycogen breakdown. We used three different cellular models to evaluate the efficiency of different read-through agents (including amlexanox, Ataluren, RTC13 and G418) in McArdle disease. The first model consisted of HeLa cells transfected with two different GFP-PYGM constructs presenting the Pygm p.R50X mutation (GFP-PYGM p.R50X and PYGM Ex1-GFP p.R50X). The second cellular model was based on the creation of HEK293T cell lines stably expressing the PYGM Ex1-GFP p.R50X construct....
