sed on lncRNA expression can effectively predict the OS of HCC patients with fibrosis as well as the OS or RFS of HCC patients without fibrosis.Anaplastic thyroid carcinoma (ATC) is a highly aggressive tumor with a poor prognosis and a low median survival rate because of insufficient effective therapeutic modalities. Recently, mesoporous silica nanoparticles (MSNs) as a green non‑toxic and safe nanomaterial have shown advantages to be a drug carrier and to modify the targeting group to the targeted therapy. To aim of the study was to explore the effects of MSNs co‑loading with 17‑allylamino‑17‑demethoxy‑geldanamycin (17‑AAG; HSP90 inhibitor) and 9‑(6‑aminopyridin‑3‑yl)‑1‑(3‑(trifluoromethyl)phenyl)benzo[h][1,6]naphthyridin‑2(1H)‑one (Torin2; mTOR inhibitor) by targeting vascular endothelial growth factor receptor 2 (VEGFR2) on the viability of human anaplastic thyroid carcinoma FRO cells. The cytotoxicity of 17‑AAG and Torin2 were analyzed by MTT assay. The possible synergistic antitumor effects between 17‑AAG and Torin2 were evaluated by CompuSyn software. Flow cytometry was performed to assess the VEGFR2 targeting of (17‑AAG+Torin2)@MSNs‑anti‑VEGFR2 ab and uptake by FRO cells. An ATC xenograft mouse model was established to assess the antitumor effect of (17‑AAG+Torin2)@MSNs‑anti‑VEGFR2 ab in vivo. The results revealed that the combination of 17‑AAG and Torin2 inhibited the growth of FRO cells more effectively compared with single use of these agents. Additionally, the synergistic antitumor effect appeared when concentration ratio of the two drugs was 11 along with total drug concentration greater than 0.52 µM. Furthermore, in an ATC animal model, it was revealed that the (17‑AAG+Torin2)@MSNs‑anti‑VEGFR2 ab therapy modality could most effectively prolong the median survival time [39.5 days vs. 33.0 days (non‑targeted) or 27.5 days (control)]. Compared to (17‑AAG+Torin2)@MSNs, the (17‑AAG+Torin2)@MSNs‑anti‑VEGFR2 ab could not only inhibit ATC cell growth but also prolong the median survival time of tumor‑bearing mice in vivo and vitro more effectively, which may provide a new promising therapy for ATC.After the publication of the article, the authors have realized that Figs. 3 and 7 in their paper were published with errors; in the first instance, regarding Fig. 3, panels ‘C’ and ‘D’ contained partially overlapping data and were derived from the same original source, where these images were intended to show the effect of 2 ng/ml sunitinib and 2 µg/ml HM‑3, respectively, on cell migration. Likewise, in Fig. 7, panels ‘C’ and ‘D’ also contained partially overlapping data derived from the same original source, even though these images were intended to show representative images for sections of tumor tissue from the HM‑3 (3 mg/kg) and HM‑3 (48 mg/kg) treatment groups. These errors arose inadvertently, as a consequence of the authors’ mishandling of their data. The revised versions of Figs. 3 and 7, featuring the corrected data panels for panels ‘C’ and ‘D’ in both Figures, are shown opposite. The revised data shown for these Figures do not affect the overall conclusions reported in the paper. The authors apologize to the Editor of Oncology Reports and to the readership for any inconvenience caused.

Even after curative surgery and adjuvant chemotherapy, peritoneal recurrences often develop. Exosomes play pivotal roles in tumor metastasis via the transfer of microRNAs (miRNAs). In the present study, exosomes were isolated from peritoneal lavage fluid or ascites in 85 patients with gastric cancer and the relative expression levels of miR‑29s were examined. The expression of miR‑29a‑3p, miR‑29b‑3p and miR‑29c‑3p in peritoneal exosomes were all downregulated in patients with peritoneal metastases (PM) compared to those without PM. In 30 patients who underwent curative gastrectomy with serosa‑involved (T4) gastric cancer, 6 patients exhibited recurrence in the peritoneum within 12 months. The expression levels of miR‑29s at gastrectomy tended to be lower in these 6 patients than in the other 24 patients with significant differences in miR‑29b‑3p (P=0.003). When the patients were divided into two groups based on median levels of miR‑29s, peritoneal recurrence developed more frequently in patients with low expression of miR‑29b‑3p, and lower expression of miR‑29s were related with worse overall survival. miR‑29s are thought to play a suppressive role in the growth of disseminated peritoneal tumor cells. Reduced expression of miR‑29b in peritoneal exosomes is a strong risk factor of developing postoperative peritoneal recurrence.The capacity that G protein‑coupled receptor 30 (GPR30) has demonstrated for triggering estrogen‑dependent signaling pathways has attracted the interest of breast cancer researchers; however, the reported expression profiles and functions of GPR30 in breast cancer are inconsistent. The main purpose of the present investigation was to identify transcriptional mechanisms underlying the expression of GPR30 that allow a better understanding of its role in breast cancer progression. In the cell lines used as different polarity models in the present study, it was determined immunologically that GPR30 is expressed in normal mammary gland cells and that this expression decreased considerably during breast cancer development, where cell identity is lost. However, it was also determined that, in spite of low GPR30 expression levels in breast cancer cells with little differentiation, this membrane estrogen receptor (ER) is able to increase cell viability and suppress migration in cells that have acquired metastatic capacity. DMH1 In addition, through transient expression assays in breast cancer cells, it was revealed that a transcriptional mechanism dependent on protein kinase A and susceptible to retinoic acid in ER‑positive cells induces GPR30 expression through a cis‑regulatory element for E26 transformation‑specific transcription factors, located between ‑631 and ‑625 bp from the GPR30 translation start codon. Overall, these results suggested that in vitro transcriptional regulation of GPR30 expression in breast cancer cells may serve a relevant role in the conservation of an epithelial phenotype, and also may be important to avoid the transition to metastasis.
