Colorectal cancer (CRC) is one of the most common gastrointestinal cancers worldwide. It is a complicated and often fatal cancer, and is related to a high disease-related mortality. Around 90% of mortalities are caused by the metastasis of CRC. Current treatment statistics shows a less than 5% 5-year survival for patients with metastatic disease. The development and metastasis of CRC involve multiple factors and mechanisms. The Hedgehog (Hh) signaling plays an important role in embryogenesis and somatic development...

In the previous study, it was found that long intergenic noncoding RNA-p21 (lincRNA-p21) was downregulated in hepatocellular carcinoma (HCC) and lincRNA-p21 overexpression inhibited tumor invasion through inducing epithelial-mesenchymal transition. However, the underlying mechanism was not fully elaborated. In this study, lincRNA-p21 expression was measured in 12 paired HCC and nontumor adjacent normal tissues by quantitative real-time polymerase chain reaction. The effects of lincRNA-p21 on HCC cells were studied using lentivirus expressing lincRNA-p21 vector in vitro...

BACKGROUND: miRNA is a microRNA that negatively regulates protein expression at post-transcriptional or translational level. It is widely involved in the pathogenesis of tumors. miR-98 belongs to the let-7 family, and its overexpression can increase the sensitivity to drugs in solid cancer cells. However, the function of miR-98 in leukemia is still unclear. In this study, the effect of miR-98 on drug resistance and proliferation of leukemia cells were investigated. METHODS: Real-time quantitative polymerase chain reaction analyzed the expression difference between miR-98 and E2F1 in leukemia cell lines, K562 and K562/A02...

Prostate cancer, the second most common cancer in men, has been rarely explored by integrating mRNA and miRNA expression profiles. In this study, we combined two mRNA expression datasets and six documented miRNAs to uncover the comprehensive molecular mechanism of prostate cancer. Results showed that a total of 30 genes were significantly differentially expressed in 49 tumor samples by comparing with 22 normal samples. Importantly, all samples from the two datasets can be clearly classified into two groups, tumor group and normal group, based on the selected differentially expressed genes (DEGs)...

AIMS: Poor efficacy of chemotherapy drugs in non-small-cell lung cancer (NSCLC) is the key reason for the failure of treatment, but the mechanism of this remains largely unknown. Stromal cell-derived factor 1-alpha (SDF-1α/CXCL12) is a small chemotactic cytokine protein that plays an important role in tumor progression. In this study, we investigated the anti-apoptotic mechanism of the CXCL12/CXCR4 axis in response to cisplatin, a commonly used chemotherapeutic drug, in human lung adenocarcinoma A549 cells...

A 62-year-old female patient with renal dysfunction and pulmonary adenocarcinoma developed postoperative recurrence and received carboplatin/pemetrexed and maintenance pemetrexed. As an anaplastic lymphoma kinase (ALK) gene translocation was identified, the therapy was changed to crizotinib. However, the patient's blood creatinine level increased, and her physical status worsened. Alectinib also induced exacerbation of renal dysfunction but was controlled by dose reduction of 140 mg twice daily for 2 weeks treatment and 2 weeks break were repeated, and exhibited a partial response for 16 months...

BACKGROUND: Studies on the association between two single nucleotide polymorphisms (SNPs) in estrogen receptor α (ERα), PvuII (rs2234693 T>C) and XbaI (rs9340799 A>G), and the prostate cancer risk are inconsistent. Therefore, we performed a meta-analysis to derive a more accurate estimation of this relationship. METHODS: A literature search of PubMed, Embase, Web of Science databases until October 1, 2016, was conducted. Crude odds ratios (ORs) with 95% confidence intervals (CIs) were calculated to assess the strength of this association...

Anaplastic lymphoma kinase (ALK) rearrangement responds to ALK tyrosine kinase inhibitors (TKIs) in lung cancer. Many cases ultimately acquire resistance to crizotinib. Resistance, including ALK-dominant or ALK non-dominant, mechanisms have been described. Transformation to small-cell lung cancer is rare. Herein, we report a 49-year-old man diagnosed with adenocarcinoma, who was negative for EGFR and ALK genes as detected by reverse transcription polymerase chain reaction, and was treated with crizotinib. A new biopsy showed a small-cell lung cancer after disease progression...

Aberrant histone methylation contributes to the progression and development of many tumors. Histone methylation is a dynamic process regulated by both histone demethylase and histone methyltransferase, which ultimately alters the levels of gene transcription. However, the relationship between histone demethylase and histone methyltransferase, as well as their regulatory mechanisms in ovarian cancer development, is still unclear. Lysine-specific demethylase 2B (KDM2B) is a key demethylase of H3K36me3 and H3K4me3 that regulates gene expression and plays a role in tumorigenesis via epigenetic mechanisms...
