Pro-cachectic factors link experimental and human chronic kidney disease to skeletal muscle wasting programs

ABSTRACT: Skeletal muscle wasting is commonly associated with chronic kidney disease (CKD), resulting in increased morbidity and mortality. However, the link between kidney and muscle function remains poorly understood. Here, we took a complementary interorgan approach to investigate skeletal muscle wasting in CKD. We identified an increased production and elevated blood levels of soluble pro-cachectic factor Activin A, directly linking experimental and human CKD to skeletal muscle wasting programs. Systemic pharmacological blockade of Activin A using soluble activin receptor type IIB ligand trap prevented muscle wasting in a mouse model of experimental CKD.

Pro-cachectic factors link experimental and human chronic kidney disease to skeletal muscle wasting programs

Project description:Skeletal muscle wasting is commonly associated with chronic kidney disease (CKD), resulting in increased morbidity and mortality. However, the link between kidney and muscle function remains poorly understood. Here, we took a complementary interorgan approach to investigate skeletal muscle wasting in CKD. We identified an increased production and elevated blood levels of soluble pro-cachectic factor Activin A, directly linking experimental and human CKD to skeletal muscle wasting programs. Single cell sequencing data identified the expression of Activin A in specific kidney cell populations, namely a subpopulation of fibroblasts and cells of the juxtaglomerular apparatus. Based on our findings, we propose that persistent and increased kidney production of pro-cachectic factors combined with a lack of kidney clearance facilitate a vicious signalling kidney-muscle cycle, leading to exacerbated blood accumulation of Activin A, and thereby skeletal muscle wasting in CKD.

The effects of doxorubicin and blocking activin receptor 2B ligands in mice [muscle]

Project description:Doxorubicin is a widely used and effective anthracycline chemotherapy drug. However, it causes cardiotoxicity and also a few negative effects on skeletal muscle as well. As a result, cancer treatment might actually worsen cancer-induced cachexia and consequently the prognosis of the disease. Inhibiting myostatin/activin signaling is known to increase muscle size. This pathway blockade by soluble activin receptor IIB (sAcvR2B-Fc) has also prolonged survival in cancer, even of animals in which tumor growth is not inhibited. It is not known, however, whether blocking this pathway affects chemotherapy-induced muscle wasting. We found that doxorubicin induces muscle atrophy which is prevented by a blocker for activin receptor 2B ligands (sAcvR2B-Fc).

ACVR2B antagonism preserves skeletal muscle and cardiac function in metastatic colorectal cancer

Project description:Advanced colorectal cancer remains a leading cause of death worldwide and is often accompanied by the development of liver metastases, as well as cachexia, a multi-organ wasting syndrome inclusive of both skeletal and cardiac muscle. Activin receptor type 2B (ACVR2B)-mediated signaling participates in causing skeletal wasting in several disease conditions, and its inhibition restores skeletal muscle mass and prolongs survival in cancer cacehxia. Here we wanted to asses whether ACVR2B antagonism could preserve skeletal and cardiac muscle mass and function in a model of metastatic colorectal cancer.

microRNA expression in gastrocnemicus muscle of control, SB431542 treated and cachectic mice

Project description:Cancer mediated activation of the ActRIIB-ALK4/5 heterodimer by myostatin is strongly associated with muscle wasting. Progressive skeletal muscle wasting, with or without loss of adipose tissue, is observed in up to 50 per cent of all cancer patients. This multifactorial syndrome is known as cachexia, and cannot be fully reversed by conventional nutritional support. Cachexia leads to progressive functional impairment. We investigated in vitro and in vivo the efficacy of ALK4/5 receptor blockers like SB431542 in preventing muscle wasting and in this context determined muscle-related miRNA expression profiles in non-tumor bearing control mice, in SB431542 treated C26 tumor-bearing mice and in cachectic C26 tumor-bearing mice.

Skeletal muscle derived Musclin protects the heart during pathological overload

Project description:Cachexia is associated with poor prognosis in patients with chronic heart failure. The underlying mechanisms of cachexia triggered heart failure progression, however, are not well understood. Here, we investigated whether the dysregulation of myokine expression from wasting skeletal muscle and impaired inter-organ crosstalk during advanced heart failure might contribute to progression of the disease. RNA sequencing analysis from wasting skeletal muscles of mice with cardiac cachexia during long-term pressure overload revealed a strongly reduced expression of Ostn. Ostn encodes for the skeletal muscle derived myokine Musclin, which had been previously implicated in the enhancement of natriuretic peptide (NP) signaling. Using newly developed skeletal muscle specific, inducible Ostn knock-out mice, we demonstrated that reduced skeletal muscle Musclin levels exaggerated cardiac dysfunction and myocardial fibrosis compared to littermate control mice after TAC. Restoration of Musclin deficiency during cardiac cachexia via AAV6-mediated skeletal muscle specific Musclin overexpression, in turn, attenuated left ventricular dysfunction and myocardial fibrosis. Mechanistically, we found that Musclin enhanced CNP/NPR2/cGMP signaling in cardiomyocytes, which led to improved contractility by inhibition of the cAMP degrading phosphodiesterase (PDE)3 and augmented cAMP/protein kinase A signaling. In addition, Musclin directly acted on cardiac fibroblasts to inhibit their activation. Together, our study indicates the therapeutic potential of targeting interorgan cross-talk during heart failure, for example by counteracting the impaired secretion of the Musclin from wasting skeletal muscle.

Muscle fibrosis in chronic kidney disease

Project description:Patients with chronic kidney disease (CKD) are at markedly increased risk of disability, hospitalization, and death. Impaired physical function, which is common in CKD, is a major risk factor for these poor outcomes. CKD patients perform substantially below age-predicted norms on a variety of clinically relevant physical performance tests. Altered muscle physiology is an important cause of these functional deficits. We recently described skeletal muscle fibrosis in the vastus lateralis muscle of patients with severely impaired kidney function. Greater severity of fibrosis was associated with lower leg extension strength and reduced endurance capacity, suggesting that muscle fibrosis in CKD patients is functionally significant. An important unanswered question is whether muscle fibrosis in CKD is a slowly progressive process beginning with early loss of kidney function, or a complication observed only with severe disease. Here, we examined the associations of estimated glomerular filtration rate (a measure of kidney function) with measures of fibrosis across a broad range of kidney function, and tested the effect of receiving treatment with dialysis. We also integrated muscle transcriptomic analyses to provide further insight into this novel aspect of muscle pathology in CKD.

Mitochondrial Proteomics in a murine model of CKD

Project description:This project involves TMT-labeled proteomics analysis of mitochondria isolated from skeletal muscle, heart, and kidney of mice with and without chronic kidney disease (CKD). CKD was induced by adenine-supplementation of the diet for 6 months. Mouse strain was C57BL6J mice from Jackson Lab, aged 6 months prior to start of the diet. Mitochondria were isolated from skeletal muscle, heart, and kidney and immediately snap frozen and stored at -80C until processing.

Gene expression profiling of skeletal muscles treated with a soluble activin type IIB receptor

Project description:Inhibition of the myostatin signaling pathway is emerging as a promising therapeutic means to treat muscle wasting disorders. Activin type IIB receptor is the putative myostatin receptor, and a soluble activin receptor (ActRIIB-Fc) has been demonstrated to potently inhibit a subset of TGF-β family members including myostatin. In order to determine reliable and valid biomarkers for myostatin pathway inhibition, we assessed gene expression profiles for quadriceps muscles from mice treated with ActRIIB-Fc compared to mice genetically lacking myostatin and control mice.
