A spotlight on the interplay of signaling pathways and the role of miRNAs in osteosarcoma pathogenesis and therapeutic resistance. Pathol Res Pract 2023; 245:154442. [PMID: 37031532 DOI: 10.1016/j.prp.2023.154442] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/08/2023] [Revised: 04/02/2023] [Accepted: 04/03/2023] [Indexed: 04/11/2023]
Abstract
Osteosarcoma (OS) is one of the most common bone cancers that constantly affects children, teenagers, and young adults. Numerous epigenetic elements, such as miRNAs, have been shown to influence OS features like progression, initiation, angiogenesis, and treatment resistance. The expression of numerous genes implicated in OS pathogenesis might be regulated by miRNAs. This effect is ascribed to miRNAs' roles in the invasion, angiogenesis, metastasis, proliferation, cell cycle, and apoptosis. Important OS-related mechanistic networks like the WNT/b-catenin signaling, PTEN/AKT/mTOR axis, and KRAS mutations are also affected by miRNAs. In addition to pathophysiology, miRNAs may influence how the OS reacts to therapies like radiotherapy and chemotherapy. With a focus on how miRNAs affect OS signaling pathways, this review seeks to show how miRNAs and OS are related.

Abstract
Ezrin, a plasma membrane-microfilament linker, is a cytoskeletal organizer involved in many cellular activities by binding to the membrane protein-ezrin-cytoskeletal protein complex and regulating downstream signal transduction. Increasing evidence demonstrates that ezrin plays an important role in regulating cell polarity, proliferation and invasion. In this study, we analyzed the effects of ezrin on oocytes, follicle development, embryo development and embryo implantation. We reviewed the recent studies on the modalities of ezrin regulation and its involvement in the biological processes of female reproductive physiology and summarized the current research advances in ezrin inhibitors. These studies will provide new strategies and insights for the treatment of diseases.

Abstract
Due to a lack of novel therapies and biomarkers, the clinical outcomes of osteosarcoma patients have not significantly improved for decades. The advancement of mass spectrometry (MS), peptide quantification, and downstream pathway analysis enables the investigation of protein profiles across a wide range of input materials, from cell culture to long-term archived clinical specimens. This can provide insight into osteosarcoma biology and identify candidate biomarkers for diagnosis, prognosis, and stratification of chemotherapy response. In this review, we provide an overview of proteomics studies of osteosarcoma, indicate potential biomarkers that might be promising therapeutic targets, and discuss the challenges and opportunities of mass spectrometric-based proteomics in future osteosarcoma research.

Abstract
OBJECTIVE: The N-myc downstream-regulated gene 1 (NDRG1) has been discovered as a significant gene in the progression of cancers. However, the regulatory mechanism of NDRG1 remained obscure in prostate cancer (PCa). METHODS: The miR-96-5p and NDRG1 expression levels were evaluated in PCa cell lines, prostate tissues, and validated public databases by real-time PCR, western blot analysis, and immunohistochemistry. The function of miR-96-5p and NDRG1 were investigated by wound healing and transwell assays in vitro, and mouse xenograft assay in vivo. The candidate pathway regulated by NDRG1 was conducted by the next-generation gene sequencing technique. Immunofluorescence and luciferase assay was used to detect the relation between miR-96-5p, NDRG1, and NF-kB pathway. RESULTS: Overexpressing NDRG1 suppresses the migration, invasion, and epithelial-mesenchymal transition (EMT) in vitro, and inhibits metastasis in vivo. Moreover, miR-96-5p contributes to NDRG1 deficiency and promotes PCa cell migration and invasion. Furthermore, NDRG1 loss activates the NF-KB pathway, which stimulates p65 and IKBa phosphorylation and induces EMT in PCa. CONCLUSIONS: MiR-96-5p promotes the migration and invasion of PCa by targeting NDRG1 and regulating the NF-κB pathway.

Abstract
BACKGROUND Osteosarcoma (OS) is the most common primary malignant bone tumors in children and adolescents. Large numbers of studies have focused on the long non-coding RNA (lncRNA) that plays essential roles in the progression of osteosarcoma. Nevertheless, the functions and underlying mechanisms of LncRNA NDRG1 in osteosarcoma remain unknown. METHODS Differentially expressed lncRNAs between osteosarcoma and adjacent normal tissues were identified through RNA sequencing. The role of LncRNA NDRG1 in osteosarcoma proliferation and metastasis were investigated through in vitro and in vivo functional experiments. The interaction between LncRNA NDRG1 and miR-96-5p was verified through bioinformatic analysis and luciferase reporter assay. Regulation relationship between LncRNA NDRG1 and miR-96-5p was further evaluated by the rescue experiments. Additionally, the changes in the expression of epithelial-mesenchymal transition (EMT) and the PI3K/AKT pathway were verified by Western blot. RESULTS LncRNA NDRG1 was up-regulated in osteosarcoma cell lines and tissues and the expression of LncRNA NDRG1 was correlated with the overall survival of osteosarcoma patients. Functional experiments exhibited that LncRNA NDRG1 aggravated osteosarcoma proliferation and migration in vitro; meanwhile, animals experiments showed that LncRNA NDRG1 promoted osteosarcoma growth and metastasis in vivo. Mechanistically, LncRNA NDRG1 was found to aggravate osteosarcoma progression and regulate the PI3K/AKT pathway by sponging miR-96-5p. CONCLUSIONS LncRNA NDRG1 aggravates osteosarcoma progression and regulates the PI3K/AKT pathway by sponging miR-96-5p. Therefore, LncRNA NDRG1 could act as a prognostic marker and a therapeutic target for osteosarcoma in the future.

MicroRNAs and osteosarcoma: Potential targets for inhibiting metastasis and increasing chemosensitivity. Biochem Pharmacol 2022; 201:115094.

Abstract
Osteosarcoma (OS) is the third most common cancer in young adults after lymphoma and brain cancer. Metastasis, like other cellular events, is dependent on signaling pathways; a series of changes in some proteins and signaling pathways pave the way for OS cells to invade and migrate. Ezrin, TGF-β, Notch, RUNX2, matrix metalloproteinases (MMPs), Wnt/β-catenin, and phosphoinositide 3-kinase (PI3K)/AKT are among the most important of these proteins and signaling pathways. Despite the improvements in treating OS, the overall survival of patients suffering from the metastatic disease has not experienced any significant change after surgical treatments and chemotherapy and 5-years overall survival in patients with metastatic OS is about 20%. Studies have shown that overexpression or inhibition of some microRNAs (miRNAs) has significant effects in limiting the invasion and migration of OS cells. The results of these studies highlight the potential of the clinical application of some miRNA mimics and miRNA inhibitors (antagomiRs) to inhibit OS metastasis in the future. In addition, some studies have shown that miRNAs are associated with the most important drug resistance mechanisms in OS, and some miRNAs are highly effective targets to increase chemosensitivity. The results of these studies suggest that miRNA mimics and antagomiRs may be helpful to increase the efficacy of conventional chemotherapy drugs in the treatment of metastatic OS. In this article, we discussed the role of various signaling pathways and the involved miRNAs in the metastasis of OS, attempting to provide a comprehensive review of the literature on OS metastasis and chemosensitivity.

Abstract
Cancer has been always considered as one of the main human health challenges worldwide. One of the main causes of cancer-related mortality is late diagnosis in the advanced stages of the disease, which reduces the therapeutic efficiency. Therefore, novel non-invasive diagnostic methods are required for the early detection of tumors and improving the quality of life and survival in cancer patients. MicroRNAs (miRNAs) have pivotal roles in various cellular processes such as cell proliferation, motility, and neoplastic transformation. Since circulating miRNAs have high stability in body fluids, they can be suggested as efficient noninvasive tumor markers. MiR-96 belongs to the miR-183-96-182 cluster that regulates cell migration and tumor progression as an oncogene or tumor suppressor by targeting various genes in solid tumors. In the present review, we have summarized all of the studies that assessed the role of miR-96 during tumor progression. This review clarifies the molecular mechanisms and target genes recruited by miR-96 to regulate tumor progression and metastasis. It was observed that miR-96 mainly affects tumorigenesis by targeting the structural proteins and FOXO transcription factors.

Abstract
BACKGROUND Osteosarcoma is a multiple malignant tumor in adolescents. MicroRNAs (MiRNAs) have been found to express abnormally in OS tissues and are considered as potential targets for OS prognosis and treatment. METHODS MiR-96-5p and SYK expression in clinical samples, osteoblast and OS cell lines were detected. The changes of cell proliferation, apoptosis, adhesion and metastasis of OS cells were detected by CCK-8, BrdU, caspase-3 activity and transwell assay. Dual luciferase report analysis and RNA pull-down were used to confirm binding relation of miR-96-5p and SYK. RESULTS MiR-96-5p was increased in OS tissue and cells. Moreover, miR-96-5p inhibits proliferation, adhesion and migration of HOS and Saos-2 cells, and promotes cell apoptosis. SYK has been identified to be targeted by miR-96-5p. Overexpressed SYK inhibits the suppressive impact of miR-96-5 on OS cells. CONCLUSION MiR-96-5p may function as an effective target in OS treatment.

Abstract
Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) are rare and heterogeneous tumors that present a wide spectrum of different clinical and biological characteristics. Currently, tumor grading, determined by Ki-67 staining and mitotic counts, represents the most reliable predictor of prognosis. This time-consuming approach fails to reach high reproducibility standards thus requiring novel approaches to support histological evaluation and prognosis. In this study, starting from a microarray analysis of paraffin-embedded tissue specimens, we defined the miRNAs signature for poorly differentiated NETs (G3) compared to well-differentiated NETs (G1 and G2) consisting of 56 deregulated miRNAs. We identified 8 miRNAs that were expressed in all GEP-NETs grades but at different level. Among these miRNAs, miR-96-5p expression level was progressively higher from grade 1 to grade 3; inversely, its target FoxO1 expression decreased from grade 1 to grade 3. Our results reveal that the miRNAs expression profile of GEP-NET is correlated with the tumor grade, showing a potential advantage of miRNA quantification that could aid clinicians in the classification of common GEP-NETs subtypes. These findings could reliably support the histological evaluation of GEP-NETs paving the way toward personalized treatment approaches.

Abstract
We previously performed high throughput RNA-seq in paired eutopic and ectopic endometrial specimen of endometriosis patients, and validated the results by qRT-PCR in endometriosis endometrial tissues. MiR-96-5p was significantly downregulated in ectopic endometrial tissues compared to eutopic tissues. In order to identify the role of miR-96-5p in endometriosis and endometrial cells, and investigate the underlying mechanisms, the Ishikawa and End1/E6E7 cell lines were transfected with miR-96-5p mimics, miR-96-5p inhibitors or TGFBR1 siRNA. The expression of TGF-β/SMAD signaling pathway components and epithelial-mesenchymal transition (EMT) markers were examined by qRT-PCR and western blot, and cell viability and migration were determined by CCK-8, transwell and wound healing assays, respectively. We discovered miR-96-5p to be significantly downregulated while TGFBR1 was distinctly up-regulated in endometriosis. Overexpression of miR-96-5p inhibited endometrial cells viability and migration, while inhibition of miR-96-5p had opposite effect. Furthermore, we confirmed TGFBR1 was a direct target of miR-96-5p. Overexpression of miR-96-5p could block the TGF-β/SMAD signaling pathway via targeting TGFBR1 and reverse the TGF-β1 induced EMT in endometrial cell lines. In conclusion, we demonstrated that miR-96-5p interacted with TGF-β/SMAD signaling pathway and blocked the TGF-β1 induced EMT in endometrial cells via directly targeting TGFBR1.

Abstract
BACKGROUND Breast cancer is the leading cause of cancer deaths in women worldwide. The purpose of the current study was to investigate the potential role of miR-96-5p in breast cancer. METHODS Breast cancer tissues and matched para-cancerous tissues were collected. The expression of microRNA-96-5p (miR-96-5p) and arginine kinase 3 (AK3) was detected by quantitative real-time PCR (qRT-PCR). The correlation between miR-96-5p and AK3 was calculated by Pearson's Chi-square test. Moreover, mimics or inhibitors of miR-96-5p were applied to explore whether miR-96-5p influences the migration capacity in Transwell and wound healing assays. Bioinformatics analysis was performed to identify the target genes of miR-96-5p through the TargetScan, miRDB and miRanda databases. A luciferase reporter assay was performed to verify AK3 as a downstream target gene of miR-96-5p. RESULTS The expression of miR-96-5p was significantly increased in breast cancer tissue and breast cancer cell lines compared with para-cancerous tissue and a breast cell line, respectively. The expression of miR-96-5p negatively correlated with AK3 gene expression. AK3 was demonstrated to be a direct mRNA target of miR-96-5p. AK3 was positively associated with the overall survival of breast cancer patients. Kaplan-Meier curve and log rank test analyses revealed that decreased AK3 levels were significantly associated with reduced overall survival. miR-96-5p was shown to promote the migration of breast cancer cells through the MEK/ERK signaling pathway. CONCLUSION Our results identify a role for miR-96-5p in promoting breast cancer cell migration through activation of MEK/ERK signaling by targeting AK3.

Abstract
Progresses in multimodal treatments have significantly improved the outcomes for childhood cancer. Nonetheless, for about one-third of patients with Ewing sarcoma, rhabdomyosarcoma, or osteosarcoma steady remission has remained intangible. Thus, new biomarkers to improve early diagnosis and the development of precision-targeted medicine remain imperative. Over the last decade, remarkable progress has been made in the basic understanding of miRNAs function and in interpreting the contribution of their dysregulation to cancer development and progression. On this basis, this review focuses on what has been learned about the pivotal roles of miRNAs in the regulation of key genes implicated in childhood sarcomas.

Long noncoding RNA TP53TG1 promotes pancreatic ductal adenocarcinoma development by acting as a molecular sponge of microRNA-96. Cancer Sci 2019; 110:2760-2772. [PMID: 31325400 PMCID: PMC6726832 DOI: 10.1111/cas.14136] [Citation(s) in RCA: 42] [Impact Index Per Article: 8.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2019] [Revised: 06/29/2019] [Accepted: 07/10/2019] [Indexed: 01/01/2023] Open
Abstract
Long noncoding RNAs (lncRNAs) are emerging as key regulators in cancer initiation and progression. TP53TG1 is a recently identified lncRNA and several studies have shown that TP53TG1 may play the role of tumor suppressor gene or oncogene in different tumors. Nevertheless, the involvement of TP53TG1 in carcinogenesis of pancreatic ductal adenocarcinoma (PDAC) has not been characterized. In our studies, we identified that TP53TG1 was highly expressed in PDAC and was a novel regulator of PDAC development. Knockdown of TP53TG1 inhibited proliferation, induced apoptosis, and decreased migration and invasion in PDAC cells, whereas enhanced expression of TP53TG1 had the opposite effects. Mechanistically, TP53TG1 could directly bind to microRNA (miR)-96 and effectively function as a sponge for miR-96, thus antagonizing the functions of miR-96 and leading to derepression of its endogenous target KRAS, which is a core oncogene in the initiation and maintenance of PDAC. Taken together, these observations imply that TP53TG1 contributes to the growth and progression of PDAC by acting as a competing endogenous RNA (ceRNA) to competitively bind to miR-96 and regulate KRAS expression, which highlights the importance of the complicated miRNA-lncRNA network in modulating the progression of PDAC.

However, the function of miR211 in human osteosarcoma has not been explored intensively so far. In this study, the relationship between miR211 and EZRIN was analyzed in human osteosarcoma. Methods The expression levels of miR211 and EZRIN were measured in both human osteosarcoma cells and tissues. The direct regulatory relationship between miR211 and EZRIN was evaluated using dual-luciferase assay. The effect of miR211 and EZRIN overexpression on cell proliferation, migration/invasion, and apoptosis was detected.

Abstract
BACKGROUND Ovarian cancer (OC) is the second most common gynaecological malignancy. MicroRNAs (miRNAs) have been found to be aberrantly expressed in OC tissue and have been proposed as biomarkers and therapeutic targets for OC. RESULTS In this study, we found that miR-96-5p was up-regulated in OC tissues and OC cells compared to normal ovarian tissues and epithelial cell line. And, miR-96-5p was also up-regulated in the serum samples from OC patients compared to health participants. In addition, there was a positive correlation of miR-96-5p levels between OC tissues and serum samples. At the cellular level, overexpression of miR-96-5p promoted cell proliferation and migration in OC cells. Moreover, we further validated Caveolae1 (CAV1) as the direct target of miR-96-5p in OC cells through luciferase activity assays and western blot. CAV1 was obvious low expression in OC tissues. The overexpression of CAV1 abrogated the promotion of miR-96-5p on the OC cells proliferation and migration. Finally, we found that AKT signaling pathway was involved in this process. MiR-96-5p inhibited the phosphorylation of AKT and expression of down-stream proteins Cyclin D1 and P70 by targeting CAV1. CONCLUSIONS The above findings suggested that targeting miR-96-5p may be a promising strategy for OC treatment.

Abstract
MicroRNA-30a (miR-30a) was previously reported to serve as a tumor suppressor able to inhibit the development and progression of certain types of cancer. A number of previous studies demonstrated that zinc finger E-box binding homeobox 2 (ZEB2) may be regulated by miR-30a in clear cell renal cell carcinoma and breast cancer. However, the function of miR-30a in human nasopharyngeal carcinoma (NPC) remains unclear. The present study aimed to investigate the association between miR-30a and ZEB2 in NPC. Therefore, the expression levels of miR-30a and ZEB2 were measured in human NPC cells and tissues from patients with NPC, and the present results suggested that the expression level of miR-30a was significantly decreased in NPC tissues compared with paracancerous tissues. The direct interaction between miR-30a and the untranslated region of ZEB2 was examined using the dual-luciferase reporter assay, and ZEB2 was identified as a direct target of miR-30a. Additionally, the effects of miR-30a and ZEB2 overexpression on cell proliferation, migration, invasion and apoptosis were additionally investigated. Functional experiments identified that overexpression of miR-30a increased apoptosis and suppressed cell proliferation, cell migration and cell invasion by directly targeting ZEB2. Collectively, the present study suggested that miR-30a may serve an important role in the progression of NPC and may represent a novel target for the treatment of patients with NPC.

Abstract
Numerous microRNAs (miRNAs) have been identified as aberrantly expressed in osteosarcoma (OS). miRNAs serve important roles in the pathogenesis of OS as oncogenes or tumor suppressors. Recent studies revealed that miR‑708‑5p (miR‑708) was dysregulated in various types of human cancer; however, its roles and underlying molecular mechanisms in OS remain unknown. Therefore, the present study aimed to determine miR‑708 expression in OS, investigate the roles of miR‑708 in the progression of OS and reveal the potential mechanisms involved. It was demonstrated using reverse transcription‑polymerase chain reaction that miR‑708 was downregulated in OS tissues and cell lines. Cell Counting Kit‑8 and Transwell assays revealed that miR‑708 overexpression suppressed the proliferation and invasion of OS cells in vitro. Additionally, zinc finger E‑box binding homeobox 1 (ZEB1) was validated as a direct target gene of miR‑708 in OS cells. ZEB1 was upregulated in OS tissues; elevated ZEB1 expression was negatively correlated with the levels of miR‑708 expression. Rescue experiments indicated that ZEB1 reintroduction significantly counteracted the inhibitory effects of miR‑708 overexpression on the proliferation and invasion of OS cells. The findings may improve understanding of the roles of miR‑708 in the development of OS, and suggest that miR‑708 may be a potential novel therapeutic target in the treatment of patients with this disease.

Abstract
Background A previous study indicated that microRNA(miR)-328-3p upregulation might be critical for resveratrol-mediated suppression of metastatic ability in human osteosarcoma, implying its potential role in this malignancy. However, the clinical significance and the biological functions of miR-328-3p in osteosarcoma remain unclear. Methods miR-328-3p expression in 88 pairs of osteosarcoma and matched non-cancerous bone tissues were detected by quantitative real-time PCR. Then, the associations of miR-328-3p expression with various clinicopathological features of osteosarcoma patients were statistically analyzed. Cell Counting Kit-8 and scratch-wound healing were performed to evaluate roles of miR-328-3p in human osteosarcoma cells. After that, luciferase reporter assay, western blot analysis and rescue assay were applied to determine the underlying molecular mechanisms of miR-328-3p in osteosarcoma cells. Results miR-328-3p expression in osteosarcoma tissues was significantly lower than those in non-cancerous bone tissues (P<0.001). miR-328-3p downregulation was significantly associated with advanced surgical stage, positive metastasis and recurrence (all P<0.05). Functionally, enforced expression of miR-328-3p efficiently suppressed cell proliferation and migration in vitro. Moreover, matrix metalloprotease 16 (MMP16) was identified as a direct target of miR-328-3p in osteosarcoma cells. Notably, MMP16 overexpression partially reversed the miR-328-3p-inhibited cell proliferation and migration of osteosarcoma cells. Conclusions Our data indicated that the aberrant expression of miR-328-3p may play a crucial role in malignant progression of human osteosarcoma. More importantly, miR-328-3p may function as a tumor suppressor inhibiting osteosarcoma cell proliferation and migration partially mediated by regulating of MMP16.

Abstract
Drug resistance remains a major cause of relapse and therapeutic failure in acute myeloid leukemia (AML). Metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) has been documented to act as an oncogene and is frequently highly expressed in human cancers including AML. However, the function and molecular mechanism of MALAT1 in regulating cytarabine (Ara-C) resistance of AML are largely unknown. The expressions of MALAT1 and miR-96 in AML patients and healthy controls were examined by qRT-PCR. CCK-8 and flow cytometry assay were performed to assess the proliferation and apoptosis of AML cells. The interaction between MALAT1 and miR-96 was investigated by luciferase reporter assay. We found that MALAT1 was upregulated while miR-96 was downregulated in AML patients compared with healthy controls. A negative correlation between MALAT1 and miR-96 expressions was observed in AML patients. Knockdown of MALAT1 inhibited the proliferation, induced apoptosis, and enhanced Ara-C sensitivity of AML cells. Additionally, MALAT1 suppressed miR-96 expression by acting as a molecular sponge of miR-96 in AML cells. miR-96 downregulation abolished the effects of MALAT1 knockdown on the proliferation, apoptosis, Ara-C sensitivity in AML cells. In conclusion, MALAT1 knockdown inhibited proliferation, promoted apoptosis and enhanced Ara-C sensitivity in AML cells by upregulating miR-96, providing novel insights into the critical role of MALAT1 as a miRNA sponge in AML.

Abstract
In recent years, microRNA-193b (miR-193b) is regarded as a tumor suppressor in the development and progression of various cancers. Several studies have indicated that KRAS could be regulated by miR-193b in pancreatic cancer cells. However, the function of miR-193b in human esophageal squamous cell carcinoma has not been explored intensively thus far. Herein, the relationship between miR-193b and KRAS was mainly explored in esophageal squamous cell carcinoma cells. In the present study, the expression levels of miR-193b and KRAS were assessed in both human esophageal cancer cells and tissues. The direct regulatory relationship between miR-193b and KRAS was evaluated using dual-luciferase assay. The effect of miR-193b overexpression and inhibitor on cell proliferation, migration/invasion, and apoptosis was further detected herein. Our results indicated that the expression of miR-193b was significantly lower in human esophageal cancer tissues than paracancerous tissues. The expression level of miR-193b/KRAS was stage-dependent in human esophageal cancers. KRAS was indicated as the direct target of miR-193b, and upregulation of miR-193b increased the percentage of cell apoptosis, and suppressed cell proliferation as well as cell migration/invasion via direct regulation of KRAS. Therefore, our study indicated that miR-193b plays an important role in the development and progression of human esophageal squamous cell carcinoma, which may become a novel target in the treatment of human esophageal squamous cell carcinoma in the future.

Abstract
Podocyte injury, which promotes progressive nephropathy, is considered a key factor in the progression of diabetic nephropathy. The mammalian target of rapamycin (mTOR) signaling cascade controls cell growth, survival and metabolism. The present study investigated the role of mTOR signaling in regulating high glucose (HG)-induced podocyte injury. MTT assay and flow cytometry assay results indicated that HG significantly increased podocyte viability and apoptosis. HG effects on podocytes were suppressed by mTOR complex 1 (mTORC1) inhibitor, rapamycin, and further suppressed by dual mTORC1 and mTORC2 inhibitor, KU0063794, when compared with podocytes that received mannitol treatment. In addition, western blot analysis revealed that the expression levels of Thr-389-phosphorylated p70S6 kinase (p-p70S6K) and phosphorylated Akt (p-Akt) were significantly increased by HG when compared with mannitol treatment. Notably, rapamycin significantly inhibited HG-induced p-p70S6K expression, but did not significantly impact p-Akt expression. However, KU0063794 significantly inhibited the HG-induced p-p70S6K and p-Akt expression levels. Furthermore, the expression of ezrin was significantly reduced by HG when compared with mannitol treatment; however, α-smooth muscle actin (α-SMA) expression was significantly increased. Immunofluorescence analysis on ezrin and α-SMA supported the results of western blot analysis. KU0063794, but not rapamycin, suppressed the effect of HG on the expression levels of ezrin and α-SMA. Thus, it was suggested that the increased activation of mTOR signaling mediated HG-induced podocyte injury. In addition, the present findings suggest that the mTORC1 and mTORC2 signaling pathways may be responsible for the cell viability and apoptosis, and that the mTORC2 pathway could be primarily responsible for the regulation of cytoskeleton-associated proteins.
