e. The RT and RT+BFR decreased pro-oxidative MPO (RT, ∼34 ng/ml and RT+BFR, ∼27 ng/ml), improved both antioxidant defence (PON1 RT, ∼23 U/L and RT+BFR, ∼31 U/L) and cardiac autonomic function (R-R interval RT, ∼120.4 ms and RT+BFR, ∼117.7 ms), and slowed the deterioration of renal function (P less then 0.0001). Redox balance markers were inversely correlated with heart rate variability time-domain indices. Our data indicated that both training models were effective as non-pharmacological tools to increase the antioxidant defences, decrease oxidative stress and improve the cardiac autonomic function of CKD patients.Hearing loss (HL) is a major global health problem of pandemic proportions. The most common type of HL is sensorineural hearing loss (SNHL) which typically occurs when cells within the inner ear are damaged. Human induced pluripotent stem cells (hiPSCs) can be generated from any individual including those who suffer from different types of HL. The development of new differentiation protocols to obtain cells of the inner ear including hair cells (HCs) and spiral ganglion neurons (SGNs) promises to expedite cell-based therapy and screening of potential pharmacologic and genetic therapies using human models. Considering age-related, acoustic, ototoxic, and genetic insults which are the most frequent causes of irreversible damage of HCs and SGNs, new methods of genome editing (GE), especially the CRISPR/Cas9 technology, could bring additional opportunities to understand the pathogenesis of human SNHL and identify novel therapies. However, important challenges associated with both hiPSCs and GE need to be overcome before scientific discoveries are correctly translated to effective and patient-safe applications. The purpose of the present review is (a) to summarize the findings from published reports utilizing hiPSCs for studies of SNHL, hence complementing recent reviews focused on animal studies, and (b) to outline promising future directions for deciphering SNHL using disruptive molecular and genomic technologies. Transient receptor potential vanilloid 2 (TRPV2) is a Ca permeable channel and plays a role in mediating intracellular Ca current via mechanical stimuli. This study aimed to examine the expression and role of TRPV2 in adult articular cartilage and development of osteoarthritis (OA). We examined TRPV2 expression in mouse and human articular cartilage. We analyzed development of OA in Col2a1-Cre ;Trpv2 and Trpv2 littermates in the resection of the medial meniscus and medial collateral ligament model (n = 5 each), the destabilization of the medial meniscus model (n = 5 each), and the aging model (n = 8-9). We examined marker protein expression in these joints, Ca influx by mechanical stimuli, and downstream pathways in vitro. Trpv2 was expressed in mouse and human articular cartilage and ectopic ossification lesions. In all models, Col2a1-Cre ;Trpv2 mice showed enhanced degradation of articular cartilage accompanied by decreased expression of lubricin/Prg4, and marked formation of periarticular ectopic ossification. Mechanical stress-induced Ca influx was decreased by Trpv2 knockout. Prg4 induction by fluid flow shear stress was diminished in Trpv2 knockout chondrocytes, and this was mediated by the Ca /calmodulin-dependent protein kinase kinase-cyclic adenosine monophosphate response element binding protein axis. Hypertrophic differentiation was enhanced in Trpv2 knockout chondrocytes. Increased activity of calcineurin and nuclear translocation of nuclear factor of activated T cells 1 by fluid flow shear stress or TRP agonist treatment were cancelled by Trpv2 knockout. This study shows regulation of articular cartilage by TRPV2 through Prg4 induction and suppression of ectopic ossification.
