Additionally, miR‑95 antagomir suppressed the growth of U2OS xenograft tumors in a mouse model. In summary, our results suggest that miR‑95 induces OS growth in vitro and in vivo by targeting SCNN1A. Our results help clarify the mechanism underlying the miR‑95‑mediated effects on OS tumor growth, thus potentially establishing it as a diagnostic target.Long non‑coding RNAs (lncRNAs) are involved in colorectal cancer (CRC) progression, however the mechanisms remain largely unknown. The present study aimed to reveal the role and possible molecular mechanisms of a new LNCRNA, LINC00858, in CRC. LINC00858 was increased in CRC tumor tissues, and patients with high LINC00858 expression had a shorter survival time. Knockdown of LINC00858 expression suppressed cell proliferation and induced G0/G1 cell cycle arrest and apoptosis in TP53‑wild‑type CRC cells. Subsequently, using Starbase v2.0 database, miR‑25‑3p was confirmed to interact with LINC00858 and was downregulated by LINC00858. Reduction of miR‑25‑3p expression with an inhibitor significantly attenuated the biological effects of LINC00858 knockdown in CRC cells. Furthermore, using TargetScan, SMAD7 was validated to interact with miR‑25‑3p and was downregulated by miR‑25‑3p. Lastly, the ectopic overexpression of SMAD7 rescued the suppressive effects of LINC00858 knockdown in CRC cells. Collectively, the results from the present study, to the best of our knowledge, firstly demonstrated a novel LINC00858/miR‑25‑3p/SMAD7 regulatory axis that promoted CRC progression, indicating LINC00858 as a promising therapeutic target for CRC.Melatonin secreted by the pineal body is associated with the occurrence and development of idiopathic scoliosis. Melatonin has a concentration‑dependent dual effect on osteoblast proliferation, in which higher concentrations can inhibit osteoblast proliferation and induce apoptosis; however, the underlying mechanism remains unclear. In the present study, flow cytometry was used to demonstrate that osteoblast cells treated with melatonin exhibited significantly increased early and late stage apoptotic rates as the concentration increased. Chromatin condensation in the nucleus and apoptotic body formation could be observed using fluorescent microscopy in osteoblast cells treated with 2 mM melatonin. Western blotting results showed that there was an upregulation in the expression of apoptosis marker proteins [poly (ADP‑ribose) polymerase 1 (PARP‑1)], endoplasmic reticulum stress [ERS; C/EBP homologous protein (CHOP) and glucose‑regulated protein, 78 kDa (GRP78)] and autophagy [microtubule‑associated protein 1 light chain 3β (LC3)‑I/LC3II]. PARP‑1 expression was not altered when treated with ERS inhibitor 4PBA and autophagy inhibitor 3MA, whereas 4PBA or 3MA in combination with 2 mM melatonin (or the three together) significantly increased PARP‑1 expression. Furthermore, the use of septin7 small interfering RNA confirmed that increased expression of GRP78 and CHOP was related to septin7, and melatonin‑​mediated ERS was necessary for septin7 activation. These findings suggest that ERS and autophagy might occur in the early stage of treatment with a high concentration of melatonin, and each might play a protective role in promoting survival; in a later stage, ERS and autophagy might interact and contribute to the induction of apoptosis. Overall, the results indicated that septin7 may be a target protein of melatonin‑induced ERS.Cathepsin A (CTSA) is a lysosomal protease that is abnormally expressed in various types of cancer; however, the function of CTSA in lung adenocarcinoma (LUAD) is unknown. The aim of the present study was to investigate the role of CTSA during LUAD development in vitro. The Cancer Genome Atlas (TCGA) database was used to analyze the expression of CTSA mRNA in LUAD tissues. CTSA was significantly upregulated in LUAD tissues compared with normal lung tissues. Elsubrutinib BTK inhibitor To explore the effect of CTSA on LUAD in vitro, LUAD A549 cells were transfected with CTSA small interfering RNA and the hallmarks of tumorigenesis were investigated using cell proliferation, cell cycle, wound healing, invasion and western blot assays. Elsubrutinib BTK inhibitor Following CTSA knockdown, proliferation of LUAD cells was decreased and an increased proportion of LUAD cells were arrested at the G0/G1 phase, with altered expression of critical cell cycle and proliferative marker proteins, including p53, p21 and proliferating cell nuclear antigen. Moreover, CTSA knockdown decreased the migration and invasion of A549 cells, as determined by wound healing, invasion, and western blotting assays. The expression levels of key proteins involved in epithelial‑mesenchymal transition were analyzed by western blotting. CTSA knockdown enhanced the expression of E‑cadherin, but decreased the expression of N‑cadherin and β‑catenin in A549 cells. To the best of our knowledge, the present study suggested for the first time it has been identified that CTSA may serve as a tumor promoter in LUAD, enhancing the malignant progression of LUAD cells by promoting cell proliferation, migration and invasion. The results suggested that CTSA may serve as a novel therapeutic target for LUAD.The PTEN induced putative kinase 1 (PINK1) mutation is the second most common cause of autosomal recessive adolescent Parkinson's disease (PD). Furthermore, mitochondrial disorders and oxidative stress are important mechanisms in the pathogenesis of PD. Numerous members of the Wnt family have been found to be associated with neurodegenerative diseases. Therefore, the present study investigated the role of the Wnt2 gene in PINK1B9 transgenic flies, which is a PD model, and its underlying mechanism. It was identified that overexpression of Wnt2 reduced the abnormality rate of PD transgenic Drosophila and improved their flight ability, while other intervention groups had no significant effect. Furthermore, an increase in ATP concentration normalized mitochondrial morphology, and increased the mRNA expression levels of NADH‑ubiquinone oxidoreductase chain 1 (ND1), ND42, ND75, succinate dehydrogenase complex subunits B, Cytochrome b and Cyclooxygenase 1, which are associated with Wnt2 overexpression. Moreover, overexpression of Wnt2 in PD transgenic Drosophila resulted in the downregulation of reactive oxygen species and malondialdehyde production, and increased manganese superoxide dismutase (MnSOD), while glutathione was not significantly affected.
