The long non‑coding RNA (lncRNA) H19 and microRNA(miR)‑675 were reported to serve an important role in the tumorigenesis and metastasis of numerous cancer types by promoting the epithelial‑mesenchymal transition (EMT) process; however, the underlying mechanisms of action of H19 and miR‑675 in cutaneous squamous cell carcinoma (cSCC) remain unknown. The mRNA expression levels of H19 and miR‑675 were analyzed using reverse transcription‑quantitative PCR, and Cell Counting Kit‑8, wound healing and Transwell assays were performed to analyze the cell proliferation, migration and invasion of cSCC cells, respectively. The levels of cell apoptosis were also determined using a TUNEL assay. Protein expression levels of p53 and marker proteins related to the EMT process were analyzed using western blotting. In addition, a dual luciferase reporter assay was performed to determine the interactions between H19, miR‑675 and p53. The results of the present study revealed that the expression levels of H19 and miR‑675 were upregulated in cSCC tissues and cSCC cell lines. The knockdown of H19 or miR‑675 expression inhibited cell proliferation, migration and invasion, but induced cell apoptosis. In addition, the expression levels of EMT‑related markers were also downregulated. The overexpression of H19 upregulated the expression levels of its predicted target, miR‑675, which subsequently promoted the EMT process and downregulated the expression levels of p53. Conversely, the genetic silencing of H19 or miR‑675 inhibited proliferation and invasion in SCL1 and A431 cSCC cell lines. In conclusion, the findings of the present study provided novel insight into the potential role of H19 and miR‑675 in the development, metastasis and progression of cSCC, which may help the development of treatments for cSCC.Pathological changes in the epigenetic landscape of chromatin are hallmarks of cancer. Our previous study showed that global methylation of promoters may increase or decrease during the transition from gastric mucosa to intestinal metaplasia (IM) to gastric cancer (GC). Here, CpG hypomethylation of the serine/threonine kinase STK31 promoter in IM and GC was detected in a reduced representation bisulfite sequencing database. STK31 hypomethylation, which resulted in its upregulation in 120 cases of primary GC, was confirmed. Using public genome‑wide histone modification data, upregulation of STK31 promoter activity was detected in primary GC but not in normal mucosae, suggesting that STK31 may be repressed in gastric mucosa but activated in GC as a consequence of hypomethylation‑associated chromatin remodeling. STK31 knockdown suppressed the proliferation, colony formation and migration activities of GC cells in vitro, whereas stable overexpression of STK31 promoted the proliferation, colony formation, and migration activities of GC cells in vitro and tumorigenesis in nude mice. Patients with GC in which STK31 was upregulated exhibited significantly shorter survival times in a combined cohort. Thus, activation of STK31 by chromatin remodeling may be associated with gastric carcinogenesis and also may help predict GC prognosis.The present study aimed to determine the role and regulatory mechanism of hydrogen sulfide (H2S) in the amelioration of doxorubicin‑induced myocardial fibrosis in rats. It is hypothesized that the PI3K/AKT/mTOR signaling pathway is regulated to inhibit endoplasmic reticulum stress (ERS) and autophagy to reduce myocardial fibrosis. A total of 40 adult male Sprague Dawley rats were randomly divided into 4 groups (n=10/group). The 4 groups included the normal control group (control group), model group [doxorubicin (Dox) group], H2S intervention model group (H2S+Dox group) and H2S control group (H2S group). The model used in the present study was constructed by administering intraperitoneal injections of doxorubicin (3.0 mg/kg every other day; total of 6 injections). In addition, the intervention factor, NaHS and the donor of H2S, was also administered by intraperitoneal injection (56 µmol/kg/day), which lasted a month. Pathological changes in the rats were observed using Masson staining and transmission electronesized to be associated with the inhibition of overactivation of the ER and that of autophagy via upregulation of the PI3K/AKT/mTOR pathway.The liver is the most common site of metastasis for colorectal cancer (CRC). Metastasis suppressor 1 (MTSS1), a potential tumor suppressor gene associated with tumor metastasis, has been reported to play an important role in cancer development. The present study aimed to investigate the effects and underlying mechanisms of MTSS1 on the biological behavior of CRC cells both in vitro and in vivo. A CRC mouse model with a high liver metastatic potential was established by injecting mice with SW1116 cells, and the association between MTSS1 expression levels and the metastatic potential of forming liver metastasis lesions was subsequently analyzed. MTSS1 gain‑ and loss‑of‑function experiments were performed by transfecting the CRC cell lines, SW1116 and DLD‑1, with Plvx‑IRES‑ZsGreen1‑MTSS1 plasmid and short hairpin RNA, respectively. Cell proliferation, migration, invasion and cell cycle distribution were analyzed by MTT, Transwell and flow cytometric assays, respectively. selleck compound To further determine the underlying mechanisms of MTSS1 in CRC, the expression levels of cell surface chemokine C‑X‑C receptor 4 (CXCR4) and its downstream signaling factors, Rac and cell division cycle 42 (CDC42), were analyzed with or without C‑X‑C motif chemokine ligand 12 (CXCL12) stimulation. The results revealed that as the CRC metastatic potential increased, the expression levels of MTSS1 decreased. The overexpression of MTSS1 exerted an inhibitory effect on cell proliferation, migration and invasion, while the knockdown of MTSS1 exerted the opposite effects in vitro. Flow cytometric analysis and western blot analysis demonstrated that MTSS1 negatively regulated the expression levels of cell surface CXCR4 and its downstream signaling pathway activation. On the whole, the results of the present study indicate that MTSS1 may play an important negative role in CRC metastasis and the underlying mechanisms may involve the downregulation of the CXCR4/CXCL12 signaling axis.
