SR-POSE: A Novel Non-Contact Real-Time Rehabilitation Evaluation Method Using Lightweight Technology.

Rehabilitation movement assessment often requires patients to wear expensive and inconvenient sensors or optical markers. To address this issue, we propose a non-contact and real-time approach using a lightweight pose detection algorithm-Sports Rehabilitation-Pose (SR-Pose), and a depth camera for accurate assessment of rehabilitation movement. Our approach utilizes an E-Shufflenet network to extract underlying features of the target, a RLE-Decoder module to directly regress the coordinate values of 16 key points, and a Weight Fusion Unit (WFU) module to output optimal human posture detection results.

Interruption of post-Golgi STING trafficking activates tonic interferon signaling.

Activation of the cGAS-STING pathway is traditionally considered a "trigger-release" mechanism where detection of microbial DNA or cyclic di-nucleotides sets off the type I interferon response. Whether this pathway can be activated without pathogenic ligand exposure is less well understood. Here we show that loss of Golgi-to-lysosome STING cofactors, but not ER-to-Golgi cofactors, selectively activates tonic interferon signalling.

Tonic prime-boost of STING signalling mediates Niemann-Pick disease type C.

The classic mode of STING activation is through binding the cyclic dinucleotide 2'3'-cyclic GMP-AMP (cGAMP), produced by the DNA sensor cyclic GMP-AMP synthase (cGAS), which is important for the innate immune response to microbial infection and autoimmune disease. Modes of STING activation that are independent of cGAS are much less well understood. Here, through a spatiotemporally resolved proximity labelling screen followed by quantitative proteomics, we identify the lysosomal membrane protein Niemann-Pick type C1 (NPC1) as a cofactor in the trafficking of STING.

Homeostatic regulation of STING protein at the resting state by stabilizer TOLLIP.

STING (stimulator of interferon genes) is an important innate immune protein, but its homeostatic regulation at the resting state is unknown. Here, we identified TOLLIP as a stabilizer of STING through direct interaction to prevent its degradation. Tollip deficiency results in reduced STING protein in nonhematopoietic cells and tissues, and renders STING protein unstable in immune cells, leading to severely dampened STING signaling capacity.

Zic1 suppresses gastric cancer metastasis by regulating Wnt/β-catenin signaling and epithelial-mesenchymal transition.

Gastric cancer (GC) patients with metastasis had limited treatment options and dismal outcome. We have previously reported the aberrant expression of Zic family member 1 (Zic1) in GC. However, the functional roles and underlying mechanism of Zic1 in GC metastasis remain unknown.

Fbxw7 increases CCL2/7 in CX3CR1hi macrophages to promote intestinal inflammation.

Resident and inflammatory mononuclear phagocytes (MPh) with functional plasticity in the intestine are critically involved in the pathology of Inflammatory Bowel Diseases (IBD), in which the mechanism remains incompletely understood. In the present study, we found that increased expression of E3 ligase FBXW7 in the inflamed intestine was significantly correlated to IBD severity in both human diseases and mice model. Myeloid-Fbxw7 deficiency protected mice from dextran sodium sulfate (DSS) and 2,6,4-trinitrobenzene sulfonic acid (TNBS) induced colitis.

SOX9/FXYD3/Src Axis Is Critical for ER Breast Cancer Stem Cell Function.

The presence of cancer stem cells (CSC), which possess the ability of self-renewal and cancer initiation, is correlated with poor prognosis and drug resistance of breast cancer patients. But the molecular regulatory networks for maintenance of CSC function still remain unclear. Here, we identified that an estrogen-inducible gene , whose expression is significantly upregulated in ER breast CSCs, is a critical player for regulating ER breast CSC function.

Ursolic acid induces autophagy in U87MG cells via ROS-dependent endoplasmic reticulum stress.

Malignant gliomas are the most common primary brain tumors, and novel ways of treating gliomas are urgently needed. Ursolic acid (UA), a pentacyclic triterpenoid, has been reported to exhibit promising antitumor activity. Here, we evaluated the effects of UA on U87MG cells and explored the underlying molecular mechanisms.
