Background: As one of the most common diseases in terms of cancer-related mortality worldwide, gastric adenocarcinoma (GA) frequently develops peritoneal metastases (PMs) in advanced stages. Systemic therapy or optimal supportive care are recommended for advanced GA; however, patients frequently develop drug resistance. Surgical resection is not recommended for stage IV patients, and there have been some controversies regarding the role of it in GA patients with PMs.

Background/aims: The prognosis for hepatocellular carcinoma (HCC) with cirrhosis is poor. The risk of death also increases in patients with esophagogastric varices (EGV). Based on routine clinical features and related noninvasive parameters, a nomogram prediction model was developed in this study to facilitate the early identification of EGV in HCC patients.

Reactive oxygen species (ROS) plays an essential role in the development of cancer. Here, we chose ROS-related miRNAs for consensus clustering analysis and ROS score construction. We find that ROS is extremely associated with prognosis, tumor immune microenvironment (TIME), gene mutations, N6-methyladenosine (m6A) methylation, and chemotherapy sensitivity in hepatocellular carcinoma (HCC).

Radiotherapy improves the survival rate of cancer patients, yet it also involves some inevitable complications. Radiation-induced heart disease (RIHD) is one of the most serious complications, especially the radiotherapy of thoracic tumors, which is characterized by cardiac oxidative stress disorder and programmed cell death. At present, there is no effective treatment strategy for RIHD; in addition, it cannot be reversed when it progresses.

Breast cancer is the most frequently diagnosed cancer among women worldwide. Though advances in diagnosis and treatment have prolonged overall survival (OS) for patients with breast cancer, metastasis remains the major obstacles to improved survival for breast cancer patients. The existence of breast cancer stem cells (BCSCs) is a major reason underlying cancer metastasis and recurrence.

Recently, -methyladenosine (mA) RNA methylation in eukaryotic mRNA has become increasingly obvious in the pathogenesis and prognosis of cancer. Moreover, tumor microenvironment is involved in the regulation of tumorigenesis. In our research, the clinical data, including 374 tumor and 50 normal patients, were obtained from The Cancer Genome Atlas (TCGA).

Background: Dihydroartemisinin (DHA) is a predominant compound in L., and it has been shown to inhibit tumorigenesis.

Methods: In this study, the antitumor potential of DHA was investigated in the MHCC97-L hepatocellular carcinoma cell line.

Accumulating evidence has shown that long non-coding RNAs (lncRNAs) had malfunctioning roles in the development of human cancers, especially lung adenocarcinoma (LC). In the present study, we aimed to investigate the role and potential mechanism of lncRNA long intergenic non-protein coding RNA 460 (LINC00460) in LC progression using human tissues and cell lines. We observed that LINC00460 was increased in lung adenocarcinoma tissues and cells in comparison to their corresponding controls.

Aim Of Study: To examine the function of lenalidomide (LEN) on the human multidrug resistance (MDR)-type gastric cancer line SGC7901/vincristine (VCR) via regulating Notch signaling.

Materials And Methods: Quantitative polymerase chain reaction was used for checking the genes of Notch, DNA methyltransferase (DNMT), RBP-J, Hes1/5, Deltex1, MDR/multidrug resistant protein (MRP); the cell proliferation and cell death were detected by cell counting kit-8 (CCK8) staining, Ki-67 expression, and propidium-iodide staining, and methylated DNA immunoprecipitation assay (MeDIP) was used for checking the 5 mC enrichment, indicating the DNA methylation of the Notch2 gene loci.

Results: LEN reduced the mRNA expression of Notch2 (P < 0.

Long non-coding RNAs have previously been demonstrated to play important roles in regulating human diseases, especially cancer. However, the biological functions and molecular mechanisms of long non-coding RNAs in hepatocellular carcinoma have not been extensively studied. The long non-coding RNA CASC2 (cancer susceptibility candidate 2) has been characterised as a tumour suppressor in endometrial cancer and gliomas.

The aim of this study was to investigate the role of G-protein signaling modulator 2 in the carcinogenesis and progression of hepatocellular carcinoma. We previously showed that G-protein signaling modulator 2 was upregulated in hepatitis B virus-related hepatocellular carcinoma tissues through a hierarchical clustering analysis. With this study, we first assessed the expression pattern of G-protein signaling modulator 2 in hepatocellular carcinoma specimens and adjacent noncancerous tissues; clinical data were analyzed, along survival times, utilizing the Kaplan-Meier method.

Long non-coding RNAs (lncRNAs) have been identified as critical players in multiple cancers and lncRNAs are tightly linked to cancer progression. However, only little amount of lncRNAs have been identified to participate in the molecular mechanisms of the progression of hepatocellular carcinoma. In this study, we found that lncRNA-AK058003 is down-regulated in hepatocellular carcinoma tissues and it is associated with the relapse and metastasis of the cancer.

Epithelial-mesenchymal transition (EMT) is a crucial process providing cancer cells with the ability to migrate and metastasize to distant sites. Recently, EMT was shown to be associated with the cancer stem cell (CSC) phenotype and chemoresistance. Twist is a transcription factor that regulates EMT in a various cancer cells, including colorectal cancer (CRC).

To investigate the expression level of NEK2 in 40 tissue specimens of primary liver cancer and to search for clues whether the effect of NEK2 depletion plays a role on biological behaviors of HepG2 cells and the relevant molecular mechanism are the objectives of this study. Real-time PCR and immunohistochemistry assessed expression level of NEK2 in specimens of cancerous tissues and carcinoma-adjacent tissues. The NEK2 expression level in HepG2, Huh7, SMMC, and 7402 cells was detected by real-time PCR and western blot to screen experimental cell line.

Aim: To study the expression of long noncoding RNAs (lncRNAs) in hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC).

Methods: The lncRNA profiles between HBV-related HCC tissues and corresponding normal liver tissues were generated using microarray analysis. Datasets were analyzed using multiple algorithms to depict alterations in gene expression on the basis of gene ontology (GO), pathway analysis, and lncRNA levels.

Background: 12-lipoxygenase (12-LOX) has been reported to be an important gene in cancer cell proliferation and survival, and tumor metastasis. However, its role in hepatocellular carcinoma (HCC) cells remains unknown.

Methods: Expression of 12-LOX was assessed in a diethyl-nitrosamine-induced rat HCC model, and in SMMC-7721, HepG2 and L-02 cells using immunohistochemical staining and reverse transcriptase-polymerase chain reaction (RT-PCR).

Objective: To investigate whether hepatic oval cells are activated in diethylnitrosamine (DEN)-induced rat liver cirrhosis, and to explore its mechanism.

Methods: Liver cirrhosis was induced in rats (n=8) by weekly intraperitoneal injections of DEN at a dose of 50mg/kg body weight for 12 weeks followed by a 2-week wash out period. Rats (n=5) that received isovolumic vehicle served as the control group.
