The results of the present study revealed that FER1L4 expression levels were downregulated in AMC‑HN‑8 and Tu 686 cells. Notably, FER1L overexpression significantly reduced the cell viability, proliferation, migration and invasion of LSCC cells, while promoting apoptosis. Meanwhile, the plasmid‑FER1L4 also significantly suppressed the phosphorylation levels of AKT and ERK. Further studies indicated that the aforementioned changes could be reversed by IGF‑1, indicating FER1L4 may regulate the progression of LSCC cells by inhibiting the AKT/ERK signaling pathway. In conclusion, the present study provided a potential novel direction for the treatment of LSCC in the future and suggested that FER1L4 may be a new target in this field.Alveolar bone is vital for dental implantation and periodontal treatment. Notoginsenoside R1 (NTR1) may promote the differentiation of human alveolar osteoblasts (HAOBs), but the underlying molecular mechanisms remain unclear. The present study investigated the pro‑differentiation function of NTR1 on HAOBs in order to find new methods of dental treatment. HAOBs were surgically obtained from dental patients and the cells were isolated, cultured and identified under an inverted phase contrast microscope. The cells were treated with different concentrations of NTR1 alone or further stimulated by TNF‑α. An alkaline phosphate (ALP) activity assay and alizarin red staining were performed to detect ALP activity and mineralization of the cells, respectively. Cell viability was assayed using an MTT assay. The expressions of osteogenic‑related factors and the factors associated with the NF‑κB and Wnt/β‑catenin pathways were examined by reverse transcription‑quantitative PCR or western blot analysis. Successfully passaged HAOBs presented blue granules and red calcium deposits after staining. The viability of HAOBs was unchanged following treatment with NTR1 at ≤20 µmol/l and/or TNF‑α, but slightly reduced by 40 µmol/l NTR1. TNF‑α‑induced decreases of calcium nodules and ALP activity were decreased by NTR1 in HAOBs. TNF‑α also regulated the expressions of runt‑related transcription factor 2, osteopontin (OPN), osteocalcin (OCN), p50, phosphorylated p65, AXIN2, Dickkopf‑related protein 1 and β‑catenin, while the regulatory effect was reversed by NTR1. NTR1 promoted the differentiation of HAOBs in the TNF‑α‑induced inflammatory microenvironment through inhibiting the NF‑κB pathway and activating the Wnt/β‑catenin pathway.Hesperidin (HDN) is a bioflavonoid that serves a role as an antioxidant in biological systems. However, although HDN has hydrogen radical‑ and hydrogen peroxide‑removal activities, the role of HDN in liver ischemia/reperfusion (I/R) injury remains unknown. This study aimed to determine the role of HDN in liver I/R injury. Male C57BL/6J wild‑type (WT) mice were subjected to warm partial liver I/R injury. Liver damage was evaluated by measuring serum alanine aminotransferase (ALT) levels, cytokine production, oxidative stress indicators, tissue hematoxylin‑eosin staining and cell death. The Akt signaling pathway was examined to elucidate the underlying mechanisms. HDN had no effect on ALT levels and tissue damage in WT mice without liver I/R injury. However, HDN significantly ameliorated liver I/R injury as measured by serum ALT levels and necrotic tissue areas. HDN decreased malondialdehyde content, but increased the levels of superoxide dismutase, catalase, glutathione peroxidase and glutathione. In addition, HDN significantly attenuated the mRNA expression levels of TNF‑α, IL‑6 and IL‑1β after liver I/R injury. Furthermore, HDN protected the liver against apoptosis in liver I/R injury by increasing the levels of Bcl‑2 and decreasing the levels of cleaved‑caspase 3. Mechanistically, the levels of phosphorylated Akt were elevated by HDN during liver I/R injury. In addition, HDN could induce Akt activation in hepatocytes in vitro. Most importantly, treatment with the Akt inhibitor LY294002 in WT mice blocked the hepatoprotective effects of HDN in liver I/R injury. In summary, the results of the present study suggested that HDN may protect against liver I/R injury through activating the Akt pathway by ameliorating liver oxidative stress, suppressing inflammation and preventing hepatocyte apoptosis. HDN may be a useful factor for liver injury protection and a potential therapeutic treatment for liver I/R injury in the future.The C3a receptor (C3aR) has been reported to be involved in various physiological and pathological processes, including the regulation of cellular structure development. buy Selumetinib Expression of C3aR has been reported in podocytes; however, data concerning the role of C3aR in podocyte morphology is scarce. The aim of the present study was to examine the effect of C3aR activation on the architectural development of podocytes. An immortal human podocyte line (HPC) was transfected with a C3a expression lentivirus vector or recombinant C3a. SB290157 was used to block the activation of C3aR. The expression of C3a in HPC cells was analyzed by reverse transcription‑quantitative PCR (RT‑qPCR) and ELISAs. Phase contrast and fluorescence microscopy were used to observe the morphology of the podocytes. The adhesive ability of HPC cells was analyzed using an attachment assay. RT‑qPCR, cyto‑immunofluorescence and western blotting were used to determine the expression levels of the adhesion‑associated genes. The expression levels of tained C3aR activation in renal cells, including podocytes and podocyte progenitors, the possible role of C3aR in the dysregulation of podocyte architecture and podocyte regeneration requires further research.Human cathelicidin antimicrobial peptide and its active product, LL‑37 (CAMP/LL‑37), exhibit a broad spectrum of antimicrobial effects. An increasing number of studies have shown that human CAMP/LL‑37 also serves significant roles in various types of cancer. The primary aims of the present study were to investigate the roles and mechanisms of human CAMP/LL‑37 in oral squamous cell carcinoma (OSCC) cells. The results indicated that either LL‑37 C‑terminal deletion mutants (CDEL) or CAMP stable expression in HSC‑3 cells reduced colony formation, proliferation, migration and invasion ability of the cells. Expression analysis demonstrated that either CDEL or CAMP stable expression in HSC‑3 cells induced caspase‑3 mediated apoptosis via the P53‑Bcl‑2/BAX signalling pathway, whereas the levels of cell cycle‑related proteins, cyclin B1 and PKR‑like ER kinase, were significantly upregulated in the CAMP, but not in the CDEL overexpressing cells. Transcriptional profile comparisons revealed that CDEL or CAMP stable expression in HSC‑3 cells upregulated expression of genes involved in the IL‑17‑dependent pathway compared with the control.
