This study aims to detect expression level of long non-coding RNA (lncRNA) FLJ33360 in hepatocellular carcinoma (HCC) and its regulatory effects on accelerating malignant progression of HCC. Expression levels of FLJ33360 in 29 matched HCC tissues and paracancerous tissues were detected by quantitative real-time polymerase chain reaction (qRT-PCR). https://www.selleckchem.com/products/17-AAG(Geldanamycin).html After transfection of sh-FLJ33360#1 in Bel-7402 and HepG2 cells, changes in migratory and invasive capacities were evaluated by Transwell and wound healing assay. Potential miRNAs targeting FLJ33360 were verified. The correlation between expression levels of FLJ33360 and miRNA-140 in HCC tissues was determined. At last, potential influences of FLJ33360/miRNA-140 regulatory loop on HCC phenotypes were determined by rescue experiments. FLJ33360 was upregulated in HCC tissues relative to paracancerous ones. After knockdown of FLJ33360, migratory and invasive capacities in Bel-7402 and HepG2 cells were attenuated. There were five miRNA candidates predicted to bind FLJ33360, and miRNA-140 was the most differentially expressed by FLJ33360 regulation. Dual-luciferase reporter gene assay confirmed the binding between FLJ33360 and miRNA-140. Besides, their expression levels were negatively correlated in HCC tissues. Moreover, knockdown of miRNA-140 could stimulate metastatic ability in HCC. At last, rescue experiments verified the involvement of miRNA-140 in FLJ33360-regulated HCC progression. LncRNA FLJ33360 is upregulated in HCC. It accelerates the metastasis of HCC through targeting miRNA-140/MMP9 axis.

In our clinical work, we have found keloid patients after receiving hyperbaric oxygen (HBO) therapy reflect less pruritus and pain. The hypothesis was that patients with keloid and a history of HBO therapy would have less pruritus and pain than patients without HBO therapy, and the pruritus or pain-related factors were detected in keloid with/without HBO therapy and normal skin. Methods Three groups of samples were established keloid samples from patients with HBO therapy for two weeks before and after surgery (H group); keloid samples from patients without HBO therapy (G group); normal skin samples from patients without obvious scar (N group). Hematoxylin and eosin (H&E) staining was used to observe morphological changes. Pruritus/pain related factors Tryptophan Hydroxylase1 (TPH1), connexin-43 (Cx43) and transient receptor potential vanilloid type 1 (TRPV1) were detected by immunofluorescence and western blot technology. The expression of these factors' mRNA was also measured by the real-time quantitative polymerase chain reaction (RT-qPCR). Results Among three groups, G group presented significantly highest expression levels of TPH1, Cx43 and TRPV1, conversely, N group presented significantly lowest expression levels of TPH1, Cx43 and TRPV1. Conclusion TPH1, Cx43 and TRPV1 were overexpressed in the samples of keloid patients, indicating that the pruritus and pain of keloid might be related to these factors. Furthermore, TPH1, Cx43 and TRPV1 were expressed highest in keloid patients without HBO therapy, indicating that HBO therapy might relief pruritus of keloid patients by regulating these factors.

However, the effect of REG γ on osteosarcoma (OS) remains unclear. The objective of the present study was to explore the clinical significance of REG γ and its function in regulating the progression of OS. METHODS Quantitative reverse transcription-polymerase chain reaction (qRT-PCR), western blotting (WB) and immunohistochemistry (IHC) analyses were performed to detect the expression levels of REG γ in OS tissues and cell lines. Then, the effects of REG γ expression on OS cell behavior in vitro were analyzed by Cell Counting Kit-8 (CCK-8), ethylene deoxyuridine (EdU), colony formation, flow cytometry, wound healing and transwell assays. The protein and mRNA levels of components involved in the Wnt/β-catenin pathway were evaluated using WB and qRT-PCR, respectively. RESULTS We found that REG γ expression was significantly upregulated in both OS tissues and cell lines. Our in vitro assay results confirmed that knockdown of REG γ inhibited cell proliferation, migration, and invasion and induced apoptosis and cell cycle arrest in OS. Additionally, through WB and qRT-PCR analyses, we found that REG γ depletion markedly decreased the β-catenin, cyclin D1 and c-myc expression levels and increased the GSK-3β expression levels in OS cell lines. CONCLUSIONS Our results revealed that REG γ plays an oncogenic role in OS by activating the Wnt/β-catenin pathway, indicating that REG γ may be a promising therapeutic target for OS patients.

Its use in autoimmune diseases such as rheumatoid arthritis has been documented. However, no studies have be conducted to evaluate its application in cancer treatment either as mono or combined therapy. This study demonstrated that while Y-320 had little effect on multidrug resistance (MDR) cell lines, it induced remarkable injury to MDR tumor cells when concurrently administered with other chemotherapeutic agents. Concomitant use of Y-320 with a low dose of paclitaxel significantly sensitized MDR tumors by inducing G2/M phase arrest and apoptosis. Further analyses indicated that Y-320 was a substrate of P-glycoprotein (P-gp). It could inhibit P-gp efflux function without altering P-gp expression, and subsequently reverse P-gp mediated drug resistance in MDR cells. The co-administration of Y-320 and paclitaxel suppressed tumor growth remarkably with an inhibition rate of 77.1% compared to 6.5% in the paclitaxel monotherapy group in vivo. This co-treatment did not increase extra complications in MDR tumor xenograft models. Particularly, no significant changes in body weight and hepatorenal serology were observed with the co-treatment. In conclusion, our results confirm that Y-320 is a promising chemotherapy sensitizer for the first time. The co-administration of Y-320 and chemotherapeutic agents might be an effective and low-toxicity chemotherapeutic regime for the MDR tumor patients. AJTR Copyright © 2020.
