LIX1 regulates YAP activity and controls gastrointestinal cancer cell plasticity.
ure S Abstract Gastrointestinal stromal tumours (GISTs), the most common mesenchymal neoplasm of the gastrointestinal tract, result from deregulated proliferation of transformed KIT-positive interstitial cells of Cajal that share mesenchymal progenitors with smooth muscle cells. Despite the identification of selective KIT inhibitors, primary resistance and relapse remain a major concern. Moreover, most patients develop resistance partly through reactivation of KIT and its downstream signalling pathways. We previously identified the Limb Expression 1 (LIX1) gene as a unique marker of digestive mesenchyme immaturity...

Hydrogen sulphide ameliorating skeletal muscle atrophy in db/db mice via Muscle RING finger 1 S-sulfhydration.
In this study, db/db mice and C2C12 myoblasts treated by high glucose and palmitate and oleate were chose as animal and cellular models. We explored how exogenous H2 S attenuated the degradation of skeletal muscle via the modification of MuRF1 S-sulfhydration in db/db mice. Our results show cystathionine-r-lyase expression, and H2 S level in skeletal muscle of db/db mice was reduced. Simultaneously, exogenous H2 S could alleviate ROS production and reverse expression of ER stress protein markers. Exogenous H2 S could decrease the ubiquitination level of MYOM1 and MYH4 in db/db mice. In addition, exogenous H2 S reduced the ...

Positive feedback in Cav-1-ROS signalling in PSCs mediates metabolic coupling between PSCs and tumour cells.
In this study, we aimed to investigate the effect of pancreatic stellate cell (PSC) Cav-1 on PDAC metabolism and aggression. We found that Cav-1 is expressed at low levels in PDAC stroma and that the loss of stromal Cav-1 is associated with poor survival. In PSCs, knockdown of Cav-1 promoted the production of reactive oxygen species (ROS), while ROS production further reduced the expression of Cav-1. Positive feedback occurs in Cav-1-ROS signalling in PSCs, which promotes PDAC growth and induces stroma-tumour metabolic coupling in PDAC. In PSCs, positive feedback in Cav-1-ROS signalling induced a shift in energy metabolism...

Autophagy regulation is an effective strategy to improve the prognosis of chemically induced acute liver injury based on experimental studies.
Abstract Acute liver injury (ALI) induced by chemicals in current experimental studies is characterized by inflammation, oxidative stress and necrosis, which can greatly influence the long-term outcome and lead to liver failure. In liver cells, different autophagy forms envelop cytoplasm components, including proteins, endoplasmic reticulum (ER), mitochondria and lipids, and they effectively participate in breaking down the cargo enclosed inside lysosomes to replenish cellular energy and contents. In general, autophagy serves as a cell survival mechanism in stressful microenvironments, but it also serves as a dest...

Preclinical insights into the gut-skeletal muscle axis in chronic gastrointestinal diseases.
Abstract Muscle wasting represents a constant pathological feature of common chronic gastrointestinal diseases, including liver cirrhosis (LC), inflammatory bowel diseases (IBD), chronic pancreatitis (CP) and pancreatic cancer (PC), and is associated with increased morbidity and mortality. Recent clinical and experimental studies point to the existence of a gut-skeletal muscle axis that is constituted by specific gut-derived mediators which activate pro- and anti-sarcopenic signalling pathways in skeletal muscle cells. A pathophysiological link between both organs is also provided by low-grade systemic inflammatio...

PCSK9 inhibitor and atorvastatin reduce cardiac impairment in ovariectomized prediabetic rats via improved mitochondrial function and Ca2+ regulation.
Abstract Post-menopausal women have a higher risk of developing cardiometabolic dysfunction. Atorvastatin attenuates dyslipidaemia and cardiac dysfunction but it can have undesirable effects including increased risk of diabetes and myalgia. Currently, the proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitor efficiently reduces low-density lipoprotein cholesterol (LDL-C) levels more effectively than atorvastatin. We have been suggested that PCSK9 inhibitor attenuated cardiometabolic impairment more effectively than atorvastatin in ovariectomized prediabetic rats. Female Wistar rats (n = 48) wer...

LncRNA SNHG3 promotes bladder cancer proliferation and metastasis through miR-515-5p/GINS2 axis.
Abstract Growing evidence suggests that long non-coding RNAs (lncRNAs) are associated with carcinogenesis. LncRNA small nucleolar RNA host gene 3 (SNHG3) is up-regulated in various cancers and positively associated with poor prognosis of these cancers. However, the precise role of lncRNA SNHG3 in bladder cancer (Bca) remains unclear. In our research, we first reported that lncRNA SNHG3 was up-regulated in bladder cancer tissues and positively related to poor clinical prognosis. Moreover, knockdown of lncRNA SNHG3 significantly suppressed the proliferation, migration, invasion and EMT process of Bca cells in vitro ...

IGFBP-4 enhances VEGF-induced angiogenesis in a mouse model of myocardial infarction.
Abstract Vascular endothelial growth factor (VEGF) is a well-known angiogenic factor, however its ability in promoting therapeutic angiogenesis following myocardial infarction (MI) is limited. Here, we aimed to investigate whether dual treatment with insulin-like growth factor binding protein-4 (IGFBP-4), an agent that protects against early oxidative damage, can be effective in enhancing the therapeutic effect of VEGF following MI. Combined treatment with IGFBP-4 enhanced VEGF-induced angiogenesis and prevented cell damage via enhancing the expression of a key angiogenic factor angiopoietin-1. Dual treatment with...

LncRNA TUG1 regulates ApoM to promote atherosclerosis progression through miR-92a/FXR1 axis.
This study aims to explore the possible mechanism of TUG1 regulating ApoM in AS. To this end, expression levels of TUG1 and ApoM were measured in high fat dieted C57BL/6J mice, normal dieted C57BL/6J mice, ob/ob mice and db/db mice. LV-TUG1 or sh-TUG1 was injected into C57BL/6J mice before isolating peritoneal macrophages to measure cholesterol efflux (CE) and expression levels of ABCA1, ABCG1 and SR-BI. Meanwhile, CE in RAW264.7 cells was also measured after cell transfection. Dual luciferase reporter assay and anti-AGO2 RIP were applied to verify the relationship among TUG1, FXR1 and miR-92a. Total cholesterol (TC), trig...

Reducing YAP expression in Pkd1 mutant mice does not improve the cystic phenotype.
Abstract The Hippo pathway is a highly conserved signalling route involved in organ size regulation. The final effectors of this pathway are two transcriptional coactivators, yes-associated protein (YAP) and transcriptional coactivator with PDZ-binding motif (WWTR1 or TAZ). Previously, we showed aberrant activation of the Hippo pathway in autosomal-dominant polycystic kidney disease (ADPKD), suggesting that YAP/TAZ might play a role in disease progression. Using antisense oligonucleotides (ASOs) in a mouse model for ADPKD, we efficiently down-regulated Yap levels in the kidneys. However, we did not see any effect ...

Dopamine and cAMP-regulated phosphoprotein 32kDa (DARPP-32), protein phosphatase-1 and cyclin-dependent kinase 5 expression in ovarian cancer.
Abstract Dopamine and cyclic-AMP activated phosphoprotein Mr32kDa (DARPP-32) is a central signalling protein in neurotransmission. Following DARPP-32 phosphorylation by protein kinase A (PKA), DARPP-32 becomes a potent protein phosphatase 1 (PP1) inhibitor. DARPP-32 can itself inhibit PKA following DARPP-32 phosphorylation by cyclin-dependent kinase 5 (Cdk5). Increasing evidence indicates a role for DARPP-32 and its associated signalling pathways in cancer; however, its role in ovarian cancer remains unclear. Using immunohistochemistry, expression of DARPP-32, PP1 and Cdk5 was determined in a large cohort of prima...

Growth differentiation factor 11 promotes differentiation of MSCs into endothelial-like cells for angiogenesis.
Abstract Growth differentiation factor 11 (GDF11) is a member of the transforming growth factor-β super family. It has multiple effects on development, physiology and diseases. However, the role of GDF11 in the development of mesenchymal stem cells (MSCs) is not clear. To explore the effects of GDF11 on the differentiation and pro-angiogenic activities of MSCs, mouse bone marrow-derived MSCs were engineered to overexpress GDF11 (MSCGDF11 ) and their capacity for differentiation and paracrine actions were examined both in vitro and in vivo. Expression of endothelial markers CD31 and VEGFR2 at the levels o...

TIPE1-mediated autophagy suppression promotes nasopharyngeal carcinoma cell proliferation via the AMPK/mTOR signalling pathway.
Abstract Recent studies have shown that tumour necrosis factor-α-induced protein 8 like-1(TIPE1) plays distinct roles in different cancers. TIPE1 inhibits tumour proliferation and metastasis in a variety of tumours but acts as an oncogene in cervical cancer. The role of TIPE1 in nasopharyngeal carcinoma (NPC) remains unknown. Interestingly, TIPE1 expression was remarkably increased in NPC tissue samples compared to adjacent normal nasopharyngeal epithelial tissue samples in our study. TIPE1 expression was positively correlated with that of the proliferation marker Ki67 and negatively correlated with patient ...

Targeting IL-11 in the treatment of BK virus-associated haemorrhagic cystitis-A promising new approach.
CA Abstract The BK polyomavirus (BKPyV) has pathogenic relevance especially in immunocompromised patients. No causal therapy has been established yet. Therefore, new therapeutic targets need to be identified in experimental studies. A 3D organotypic cell culture model with primary urothelial cells and fibroblasts was used as infection model. The detection of virus replication was performed with quantitative polymerase chain reaction (qPCR), and immunohistochemistry (IHC) was also used for analysis. Interleukin levels were measured by enzyme-linked immunosorbent assay (ELISA). Interestingly, the signal transducer ...

Exosomal MiR-500a-3p promotes cisplatin resistance and stemness via negatively regulating FBXW7 in gastric cancer.
In this study, we found that microRNA-500a-3p was highly expressed in cisplatin (DDP) resistant GC cells (MGC803/DDP and MKN45/DDP) and their secreted exosomes than that in the corresponding parental cells. MGC803/DDP-derived exosomes enhance DDP resistance and stemness properties of MGC803 recipient cells via exosomal delivery of miR-500a-3p in vitro and in vivo through targeting FBXW7. However, reintroduction of FBXW7 in MGC803 cells reverses miR-500a-3p-mediated DDP resistance as well as stemness properties. Furthermore, elevated miR-500a-3p in the plasma exosomes of GC patients is correlated with DDP resistance and the...
