The mevalonate pathway is known for the synthesis of cholesterol, but recent studies have reported that it also controls Hippo signaling, which is critical for the regulation of organ size and tumorigenesis. Here, we discover that the suppression of the mevalonate pathway inhibits the growth and proliferation of colon cancer cell lines. The results of transcriptomic and proteomic assays suggested that the mevalonate pathway controls multiple signaling pathways relevant to cell proliferation, and the results were further confirmed using western blot, PCR, and immunofluorescence assays.

Methods: The proliferation, migration and invasion capabilities of HBE-Dp71d and HBE-Dp71f cells were evaluated by MTT, colony formation, transwell and scratch assay. Cell cycle and apoptosis induced by H2O2 were measured by flow cytometer.

Introduction: Recently, there has been a controversial discussion about the prognostic value of chemotherapy-induced neutropenia (CIN) in colorectal cancer patients. Thus, a meta-analysis was conducted to determine the relationship between CIN and the prognosis of colorectal cancer patients.
Methods: We searched the PubMed, EMBASE, and Cochrane library databases to identify studies evaluating the association between CIN and colorectal cancer prognosis.
Erythropoietin-producing hepatocellular receptor A2 (EphA2) is upregulated in gastric cancer tissues and cells, which is accompanied by epithelial-mesenchymal transition (EMT). The current study was designed to establish the oxaliplatin-resistant human gastric cancer cell line SGC-7901/L-OHP, to determine if EMT in these cells could be reversed, and to determine if the susceptibility of these cells to oxaliplatin was affected by silencing EphA2 expression. We found that EphA2 expression levels were upregulated in gastric cancer and associated with chemotherapy sensitivity.

Objective: To examine the expression of liver X receptor-β (LXR-β) in human gastric cancer tissue, and to explore the effect of GW3965, an agonist of LXRs, on proliferation of gastric cancer cell line SGC-7901.
Methods: The immunohistochemical assay was used to detect the expression of LXR-β, activating transcription factor 4 (ATF4) in gastric cancer tissues and the corresponding pericarcinoma tissues in 114 patients. Real-time quantitative PCR and Western blot were used to determine mRNA and protein levels of ATF4 and ATP-binding cassette 1 (ABCA1), one of the downstream target genes of LXRs, in SGC-7901 cells with or without GW3965 treatment.
Dp71 is one of the most ubiquitously expressed isoforms of dystrophin, the pathological genes of DMD. In order to find whether the alteration of Dp71 can affect the phenotypes of cell other than PC12, an A549 cell line with stably transfected Dp71 siRNA plasmids was set up and named A549-Dp71AS cell. It is demonstrated for the first time that the A549-Dp71AS cell line displayed decreased invasion capabilities, reduced migration ability, decreased proliferation rate, and lessened clonogenic formation.

Small bowel obstructions caused by the metastatic spread of squamous cell carcinoma (SCC) of the hand to the intestines are even rarer. A 71-year-old man with intermittent abdominal distension and pain for 4 months was diagnosed with partial bowel obstruction.

Objective: To construct effective short hairpin RNA (shRNA) recombinant plasmids targeting human Dystrophin Dp71 gene, and evaluate their interference efficiency.
Methods: Three pairs of siRNA sequences targeting human Dp71 gene and one pair of control siRNA sequence were designed, synthesized, and then inserted into the pRNAT-U6.1/Neo vector.
