Microtubule Affinity-Regulating Kinase 2 is associated with DNA damage response and cisplatin resistance in non-small cell lung cancer.

ABSTRACT: MARK2 expression is associated with the malignant phenotype, expression of DNA repair components, NF-κB inhibition and cell cycle transcription factors in lung cancer cells We used microarrays to determine the global gene expression pattern associated with knockdown of MARK2 3 lung cancer cell lines overexpressing MARK2 have been selected to assess the gene expression pattern after MARK2 knockdown. RNA extraction and hybridization on Affymetrix microarrays have been done on 2 biological replicates for each line (H1993, H1693 and H1650) after shRNA lentiviral transduction and compared with respective contols using the empty vector pLKO.

Microtubule affinity-regulating kinases (MARKs) are involved in several cellular functions but few studies have correlated MARK kinase expression with cancer, and none have explored their role in lung cancer. In this study, we identified MARK2 as frequently disrupted by DNA hypomethylation and copy gain, resulting in concordant overexpression in independent lung tumor cohorts and we demonstrate a role for MARK2 in lung tumor biology. Manipulation of MARK2 in lung cell lines revealed its involvem ...[more]

Jinfukang enhances the pro-apoptotic activity of cisplatin via activation of AIFM2 in human lung cancer cells

Project description:Application of cisplatin (DDP) for treating lung cancer is restricted due to its toxicity and drug resistance. In this study, we aimed to examine whether Jinfukang (JFK), an effective herbal medicine against lung cancer, enhances DDP-induced cytotoxicity in lung cancer cells. Morphologically, we observed JFK increases DDP-induced pro-apoptosis in A549 cells in a synergistic manner. Transcriptome profiling analysis indicated that combination of JFK and DDP regulates genes involved in apoptosis-related signaling pathways. Moreover, we found the combination of JFK and DDP produces synergistic pro-apoptosis effect in other lung cancer cell lines NCI-H1975, NCI-H1650 and NCI-H2228. Particularly, we demonstrated AIFM2 is activated by the combined treatment of JFK and DDP, and partially mediate the synergistic pro-apoptosis effect. Collectively, this study gives the first evidence that activation of AIFM2 contributes to induction of pro-apoptosis by combined treatment with JFK and DDP in human lung cancer cells and provides an insight for its potential clinical application in lung cancer treatment.

microRNA Expression data from Lung cancer cell lines

Project description:GPX3 has been reported to be involved in antioxidant, anticancer, and anti-inflammation in various studies. It is also known that expression of GPX3 is low in lung cancer tissues. We performed a microarray using three lung cancer cell lines including A549, H1650, and H1975 lung cancer cell lines. Among these, A549 is highly expressed in GPX3 as compared with H1650 and h1975. Microarrays were used to analyze microRNAs showing other expression between A549 and the other two cell lines.

Expression data from Colossolactone H treated H1650 cells

Project description:Ganoderma colossum (Fr.) Baker, a white rot fungus distributed in tropical and subtropical forests, is a rare Ganoderma mushroom belonging to the family Ganodermataceae. In Asia, the fruiting body of G. colossum has been used as tonics or as folk medicine for a variety of illnesses, including malignant diseases. Colossolactone H (colo H) as a new compound was isolated and studied for its anticancer mechanism in human lung cancer H1650 cells. We used microarrays to analyze the gene expression changes upon colo H treatment that helped underlying the molecular mechanism of colo H in H1650 lung cancer cells. The H1650 cells treated with colo H for 12 and 24 h for RNA extraction and hybridization on Affymetrix microarrays.

Human tongue squamous cell carcinoma cell line SAS-Control vs. SAS-LYRIC knockdown stable clones global gene profiling

Project description:Transcriptional profiling of SAS cells transfected with pLKO.1-LYRIC shRNA-B expression vector (desinaged as B) and control SAS cells (transfected with pLKO.1 vector, designated as CTL). Goal was to determine the effects of LYRIC knockdown on global SAS cells gene expression.

RNA seq to compare gene expression profiles between Npm1 WT and Npm1 knockdown cells

Project description:Mouse KrasG12D/P53-/-(KP) lung tumor cells were transfected with pLKO.1-Tet on-shNpm1-3(N3), pLKO.1-Tet on-shNpm1-4(N4) or pLKO.1-Tet on-shNpm1-5 (N5) and then selected by using 2ug/ml puromycin, to establish the 3 stable cell lines. These 3 stable cell lines (N3, N4 or N5) were treated with 100ng/ml Doxycline and then the total RNA of the treated and untreated cells were harvested for RNA seq.

The histone lysine demethylase Kdm6b is required for activity-dependent preconditioning of hippocampal neuronal survival

Project description:We profiled basal and bicuculline+4-AP inducible mRNA expression in cultured mouse hippocampal neurons with or without viral shRNA mediated knockdown of Kdm6b We harvested mRNA from neurons under four conditions (pLKO vector/treatment control, pLKO vector/3hr bicuculline+4AP, Kdm6b knockdown/treatment control,Kdm6b knockdown/3hr bicuculline+4AP).

PRODH regultes naive pluripotency by influencing mitochondrial oxidative phosphorylation (Untargeted metabolomics)

Project description:Naïve human embryonic stem cells (hESCs) that resemble the pre-implantation epiblasts are fueled by a combination of aerobic glycolysis and oxidative phosphorylation, but their mitochondrial regulators are poorly understood. Here we report that, proline dehydrogenase (PRODH), a mitochondria-localized proline metabolism enzyme, is dramatically upregulated in naïve hESCs compared to their primed counterparts. The upregulation of PRODH is induced by a reduction in c-Myc expression that is dependent on PD0325901, a MEK inhibitor routinely present in naive hESC culture media. PRODH knockdown in naive hESCs significantly promoted mitochondrial oxidative phosphorylation (mtOXPHOS) and reactive oxygen species (ROS) production that triggered autophagy, DNA damage, and apoptosis. Remarkably, MitoQ, a mitochondria-targeted antioxidant, effectively restored the pluripotency and proliferation of PRODH-knockdown naïve hESCs, indicating that PRODH maintains naïve pluripotency by preventing excessive ROS production. Concomitantly, PRODH knockdown significantly slowed down the proteolytic degradation of multiple key mitochondrial electron transport chain complex proteins. Thus, we revealed a crucial role of PRODH in limiting mtOXPHOS and ROS production, and thereby safeguarding naïve pluripotency of hESCs. Untargeted metabolomics - H9N PLKO.1 vs H9P PLKO.1 / H9P shPRODH vs H9P PLKO.1 / H9N shPRODH vs H9N PLKO.1 - is reported in the current study <a href='https://www.ebi.ac.uk/metabolights/MTBLS7840' rel='noopener noreferrer' target='_blank'>MTBLS7840</a>.Targeted metabolomics (amino acids and derivatives) - H9P (Primed) VS H9N (Naïve) - is reported in <a href='https://www.ebi.ac.uk/metabolights/MTBLS7832' rel='noopener noreferrer' target='_blank'>MTBLS7832</a>.
