Retinoid-related orphan receptor-γ (RORγ) is a nuclear receptor that plays important roles in the development and activation of T helper type-17 (Th17) cells. In this study, we characterized the pharmacological profile of JTE-151 ((4S)-6-[(2-chloro-4-methylphenyl)amino]-4-{4-cyclopropyl-5-[cis-3-(2,2-dimethylpropyl)cyclobutyl]isoxazol-3yl}-6-oxohexanoic acid), which is a novel RORγ antagonist identified by our group. JTE-151 dissociated co-activator peptide from the human RORγ-ligand binding domain (LBD) and recruited co-repressor peptide into human RORγ-LBD, and potently inhibited the transcriptional activity of RORγ of human, mouse and rat.

  • Protein ubiquitination is crucial for various biological processes, including protein degradation and neural functions, with USP46 as a key deubiquitinase highly expressed in the brain.
  • A mutation (ΔK92) in USP46 is linked to reduced depressive behaviors in mice, yet the detailed mechanisms of its neural function regulation remain unclear.
  • Using advanced genome editing and biotinylation techniques, researchers identified 286 potential interaction partners of USP46, highlighting a significant connection between USP46 and centrosome-related proteins, suggesting a role in centrosome regulation that is separate from protein stability.

The approval of splice-switching oligonucleotides with phosphorodiamidate morpholino oligomers (PMOs) for treating Duchenne muscular dystrophy (DMD) has advanced the field of oligonucleotide therapy. Despite this progress, PMOs encounter challenges such as poor tissue uptake, particularly in the heart, diaphragm, and central nervous system (CNS), thereby affecting patient's prognosis and quality of life. To address these limitations, we have developed a PMOs-based heteroduplex oligonucleotide (HDO) technology.

The risk of virus transmission via the touching of contaminated masks has long been assumed by infection control teams. Yet, robust evidence to support this belief has been lacking. This risk was investigated in a laboratory setting by measuring the amount of viable influenza virus successfully transferred from artificially contaminated medical (surgical) mask surfaces to a human finger used to swipe their outer surface under various experimental conditions.

Spinal and bulbar muscular atrophy (SBMA) progressively impairs gait function, resulting in the need for patients to use a wheelchair approximately 20 years after onset. No reports have investigated the effects of long-term exercise training using the Hybrid Assisted Limb (HAL) in patients with multiple SBMA. This study investigated the effects of long-term exercise training using HAL in patients with SBMA and its effects on the quality of life (QoL).

Sporadic inclusion body myositis (sIBM) is a muscle disease in older people and is characterized by inflammatory cell invasion into intact muscle fibers and rimmed vacuoles. The pathomechanism of sIBM is not fully elucidated yet, and controversy exists as to whether sIBM is a primary autoimmune disease or a degenerative muscle disease with secondary inflammation. Previously, we established a method of collecting CD56-positive myoblasts from human skeletal muscle biopsy samples.

Background: Lung transplantation (LTx) is a crucial therapeutic strategy for patients suffering from end-stage respiratory diseases, necessitating precise donor-recipient size matching to ensure optimal graft function. While standard allocation protocols rely on predicted lung capacity based on factors such as sex, age, and height, a subset of patients with respiratory diseases presents an additional challenge - thoracic or vertebral deformities. These deformities can complicate accurate volume predictions and may impact the success of lung transplantation.

In Parkinson's disease and other synucleinopathies, fibrillar forms of α-synuclein (aSyn) are hypothesized to structurally convert and pathologize endogenous aSyn, which then propagates through the neural connections, forming Lewy pathologies and ultimately causing neurodegeneration. Inoculation of mouse-derived aSyn preformed fibrils (PFFs) into the unilateral striatum of wild-type mice causes widespread aSyn pathologies in the brain through the neural network. Here, we used the local injection of antisense oligonucleotides (ASOs) against Snca mRNA to confine the area of endogenous aSyn protein reduction and not to affect the PFFs properties in this model.
