Î±-catulin play a role in lung cancer metastasis

ABSTRACT: Background: Î±-catulin may functions as an oncoprotein, sustaining proliferation by preventing cellular senescence and promoting cancer cell migration. In this study, we investigated the mechanism of Î±-catulin in cancer cell migration and metastasis in lung cancer. Method: Î±-catulin mRNA expression was isolated from A549/AS2neo (control) and A549/AS2neo-Î±-catulin stable cells. The Phalanx Human OneArray microarray analysis was performed to identify Î±-catulin downstream genes. Results: Overexpression of Î±-catulin increased cancer cell migration and metastasis. By using Phalanx Human OneArray microarray we have identified panel of genes altered by Î±-catulin overexpression, consisting of CDC42, intergrins and genes related to cytoskeleton remodeling. Conclusion: Î±-catulin is an oncoprotein and promotes lung cancer cell migration and metastasis. Two-condition experiment, Vector vs. alpha-catulin overexpression cells.The cDNAs encoding full-length human alpha-catulin were amplified and subcloned into lentiviral pLKO_AS2.neo which generated full-length alpha-catulin. Vector control or alpha-catulin lentivirus were transduced into A549 cells and G418 was used to select stable cells.

α-catulin play a role in lung cancer metastasis

Project description:Background: α-catulin may functions as an oncoprotein, sustaining proliferation by preventing cellular senescence and promoting cancer cell migration. In this study, we investigated the mechanism of α-catulin in cancer cell migration and metastasis in lung cancer. Method: α-catulin mRNA expression was isolated from A549/AS2neo (control) and A549/AS2neo-α-catulin stable cells. The Phalanx Human OneArray microarray analysis was performed to identify α-catulin downstream genes. Results: Overexpression of α-catulin increased cancer cell migration and metastasis. By using Phalanx Human OneArray microarray we have identified panel of genes altered by α-catulin overexpression, consisting of CDC42, intergrins and genes related to cytoskeleton remodeling. Conclusion: α-catulin is an oncoprotein and promotes lung cancer cell migration and metastasis.

Gene expression profiles of PML knockdown or WDR4 overexpression in A549 cells

Project description:Lung cancer cell line, A549 cells, was transfected with siPML or siCtrl for 48hr to knockdown PML expression. WDR4 or vector was overexpressed in A549 cells for 48hr. These four sets of cells were then subjected to microarray profiling using the Human OneArray microarray (version HOA6.1, GEO Platform GPL19137) from Phalanx Biotech Group.

Gene expression profile of A549 Circulating Tumor Cells from 4D Model.

Project description:CTCs in cancer patients are thought to be responsible for metastasis. Currently, there is no ex vivo model that can isolate this group of cells. We have developed an ex vivo 4D lung cancer model that forms perfusable tumor nodules and form CTCs. Gene array analyses show 2504 differentially expressed genes when comparing CTCs from the 4D model seeded with A549 cells to the same cells grown on a petri dish (2D). We compared the gene expression profile (Human OneArray v5 chip) of A549 cells, human lung cancer cell line, grown on petri dish (2D) and same cells circulating as tumor cells in our ex vivo model (4D/CTC).

The Plant-derived Lipoxygenase Inhibitor Nordihydroguaiaretic Acid (NDGA) Attenuates Dyslipidemia and Hepatic Steatosis by Enhancing Fatty Acid Oxidation through Activation of PPAR-alpha

Project description:To test whether NDGA attenuate dyslipidemia and hepatic steatosis by enhancing fatty acid oxidation through activation of PPAR-α. Using wild type (WT, C57BL/6) fed with chow diet as control, WT mice were either fed with high-fat diet or high-fat diet with NDGA (2.5g/kg food); ob/ob mice were fed with either chow or chow with NDGA (2.5 g/kg food), and maintained on the respective diets for 16 weeks. The expression of lipid metabolism related genes in the liver of these mice were analyzed using Phalanx GPL6845 platform (Mouse OneArray V1). Together with other biochemical/physiological data, our results suggest that the beneficial actions of NDGA on dyslipidemia and hepatic steatosis in ob/ob mice are exerted primarily through enhanced fatty acid oxidation and energy utilization via the activation of PPAR- α receptor activity. To examine the changes in gene expression in liver of WT and ob/ob mice with different NDGA diet treatment, RNA isolated from 3 animals of each group were used for studies of gene expression profiles. Phalanx GPL6845 platform (Mouse OneArray V1) was used for the microarrays analysis.

Comparison of Ets2-null and control ES cell derived lineages

Project description:Ets2-null ES cells are defective in differentiating into cardiac myocytes, evidenced by the lack of spontaneous beating, cardiac transcription factors and structural proteins. With the Phalanx mouse Onearray v2, we compared the gene expression profiles of cells derived from Ets2-null and wildtype ES cells.

Transcriptional profiling of shoots and roots in japonica and indica rice seedlings under salt stress and recovery stage

Project description:Rice seedlings at 3-leaf stage were used for expression analysis in control and salt stressed (incloudling salt treatment for 3, 24hrs and recovery from salt stress for 24hrs) samples. Samples of shoots and roots from biological replicates of both genotypes were generated and the expression profiles were determined using Phalanx Rice OneArray＠ v1.
