OBJECTIVE To profile and correlate KRAS mutations with outcome in stage III colon cancer (CC) patients who underwent adjuvant chemotherapy following curative resection surgery. PATIENTS AND METHODS In this retrospective study, eligible patients were those with resected stage III CC who underwent 6-months adjuvant chemotherapy, either with fluoropyrimidine monotherapy (FP) or with oxaliplatin-based regimens (O-FP). Disease-free survival (DFS) and overall survival (OS) were analyzed and computed using the Kaplan-Meier method and the log-rank test. RESULTS The study population included 148 patients (n=65 FP and n=83 O-FP). We identified KRAS mutations in 41/148 (27%) patients, of which 18 (44%) received FP and 23 (56%) O-FP. Five-year DFS and OS were significantly higher in patients with KRAS wild-type vs. mutant [DFS 78 vs. 56%, HR 0.47 (95% CI 0.25; 0.87), p=0.01; OS 73 vs. 68%, HR 0.44 (95% CI 0.21; 0.88), p=0.01]. In patients treated with FP, the 5-year DFS and OS was significantly improved in the KRAS wild-type vs. mutant group, respectively [DFS 80 vs. 43%, HR 2.88 (95% CI 0.67; 3.76), p=0.014; OS 85 vs. 68%, HR 0.27 (95% CI 0.10; 0.73), p=0.005]. Conversely, 5-year DFS and OS were not statistically different for patients with KRAS wild-type vs. mutations treated with O-FP, respectively [DFS 78 vs. 65%, HR 1.59 (95% CI 0.67; 3.76), p=0.281; OS 80 vs. 75%, HR 0.73 (95% CI 0.55; 2.12), p=0.57)]. CONCLUSIONS Our results suggest that curatively resected stage III CC patients exhibiting wild-type KRAS status might benefit from FP alone. ALK inhibitor Conversely, an oxaliplatin-containing regimen should be recommended in KRAS mutated patients.OBJECTIVE To study the expression of long non-coding ribonucleic acid (lncRNA) UNC5B antisense RNA 1 (UASR1) in colorectal cancer (CRC) and its biological functions, and to discuss the regulatory effect of the transcription factor on lncRNA UASR1. PATIENTS AND METHODS The expressions of lncRNA UASR1 in the CRC tissues and cells were detected via quantitative Reverse Transcription-Polymerase Chain Reaction (qRT-PCR) assay. After the expression of lncRNA UASR1 was interfered, the change in the CRC cell proliferation ability was investigated through cell counting kit-8 (CCK-8) assay and colony formation assay, respectively. Changes in cell cycle distribution and apoptosis rate in CRC cells after transfection of small-interfering UASR1 (si-UASR1) were detected using flow cytometry. Potential transcription factors binding UASR1 promoter region were analyzed through bioinformatics. The change in the UASR1 expression was measured through the qRT-PCR assay after the paired box 5 (PAX5) expression was interfered. Folle interfered. CONCLUSIONS The transcription factor PAX5 promotes the expression of lncRNA UASR1 in CRC. The highly expressed UASR1 facilitates the malignant proliferation of CRC via the mTOR signaling pathway.OBJECTIVE This study was aimed to investigate the expression characteristics of STYXL1 in hepatocellular carcinoma (HCC), and to further analyze its regulatory role in promoting HCC development by targeting CELF2 to activate the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt) pathway. PATIENTS AND METHODS Expression levels of STYXL1 in 25 pairs of HCC tissue specimens and paracancerous normal ones collected from HCC patients were examined by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). Meanwhile, qRT-PCR was also performed to further verify the expression of STYXL1 in HCC cell lines. In addition, after STYXL1 knockdown model was constructed by lentivirus transfection in HCC cell lines Hep3B and Huh7, the Cell Counting Kit-8 (CCK-8), cell colony formation, 5-Ethynyl-2'-deoxyuridine (EdU), and flow cytometry assays were performed to analyze the influence of STYXL1 on HCC cell functions. Furthermore, an in-depth study of the relationship between STYXL1 and CELF2 was conducted to figure the poor prognosis of HCC patients. ALK inhibitor In addition, STYXL1 might be able to accelerate HCC proliferation rate and inhibit cell apoptosis via downregulating CELF2 through the PI3K/Akt pathway.OBJECTIVE The expression pattern, biological function and action mechanism of long noncoding RNA HCP5 in clear cell renal cell carcinoma (ccRCC) remain elusive. MATERIALS AND METHODS The quantitative Real Time-Polymerase Chain Reaction (qRT-PCR) was used to measure the abundance of HCP5 and miR-140-5p in HCC tissues and cells. Kaplan-Meier survival analysis was used to analyze the prognostic role of HCP5 for the patients. Cell proliferation, apoptosis, as well as cell cycle and metastasis were detected by CCK-8, flow cytometry, transwell migration and invasion assays, respectively. The binding sites between miR-140-5p and HCP5 or IGF1R were predicted by bioinformatic sites, and the direct interaction was confirmed by Dual-Luciferase reporter assay or RIP-ago2 assay. Western blot assay was used to detect the expression of target gene. Xenograft model was established to validate the function of HCP5 in vivo. RESULTS The expression of HCP5 was significantly upregulated in ccRCC tissues and cells. Moreover, patients with high HCP5 expression level had unfavorable overall survival (OS) and progression-free survival (PFS) compared to those with low HCP5 expression. Additionally, HCP5 knockdown led to the prohibition of ccRCC cell proliferation, colony formation, migration, and invasion; the promotion of cell cycle arrest at G0-G1 and apoptosis in vitro; and the inhibition of tumor growth in vivo. Mechanically, miR-140-5p was certified as an inhibitory target of HCP5. Furthermore, insulin-like growth factor-1 receptor (IGF1R) was identified as a direct target of miR-140-5p in ccRCC cells. Finally, we found that the inhibitory effects of the HCP5 silencing on functional behaviours were neutralized by miR-140-5p silencing. CONCLUSIONS HCP5 serves as a competing endogenous RNA that regulated IGF1R expression by sponging miR-140-5p in ccRCC. Hence, the HCP5/miR-140-5p/IGF1R pathway might be a promising therapeutic target in ccRCC.OBJECTIVE Bladder cancer is the most frequent tumor of the urinary system. Despite variety of new treatment options, bladder cancer remains a main global medical problem. Our purpose was to explore the potential molecular and therapeutic targets of bladder cancer diagnosis. PATIENTS AND METHODS The qRT-PCR was used to assess the expression of miR-20a in tissues and cell lines. Counting Cell Kit-8 (CCK-8) assay was carried out to evaluate cell proliferation. Cell migration was calculated using the transwell assay. RESULTS The expression of miR-20a increased and PDCD4 decreased in bladder cancer tissues compared with normal tissues. Overexpression of miR-20a promoted T24 cell proliferation and migration, while miR-20a inhibitor suppressed cell proliferation and migration. MiR-20a targeted PDCD4 to regulate its expression in T24 cells. MiR-20a is inversely related to PDCD4 and PTENPL in bladder cancer tissues. Upregulation of PDCD4 suppressed T24 cell proliferation and migration. CONCLUSIONS The PTENP1/miR-20a/PTEN axis was involved in the progression of bladder cancer.
