Study the global mRNA translation changes between SKBR cells overexpressing VIRMA and eGFP control

Project description:In order to determine whether increased m6A abundance coupled with upregulation of transcripts regulating UPR also promote their translation, we first compared levels of key UPR signalling proteins in VIRMA FL-overexpressing SKBR3 cells and eGFP control. To our surprise, none of the key UPR signalling proteins measured showed increased levels in VIRMA FL cells compared to control We then performed ribosome profiling analysis between SKBR cells overexpressing VIRMA FL and eGFP control

VIRMA-mediated m6A modification profilling in human nasopharyngeal carcinoma

Project description:Several studies revealed an underlying disordered m6A regulatory network in human nasopharyngeal carcinoma (NPC). However, the roles of m6A regulators and sequential m6A dysregulation in NPC remain largely unknown. In the present study, we investigated the role of VIRMA and its underlying mechanisms in NPC. We performed methylated RNA immunoprecipitation sequencing (MeRIP-seq) to identify the potential downstream targets of VIRMA that might be essential in NPC using HONE-1 cells with or without VIRMA silenced (two biological replicates).

Effect of VIRMA amplification on gene expression in breast cancer cells

Project description:To confirm the contribution of elevated VIRMA levels towards cell proliferation and colony formation, we depleted VIRMA in four breast cancer cell lines, SKBR3, HS578T, MCF7 and MDAMB453 using short-hairpin RNAs (shRNAs). We then performed gene expression profiling analysis using data obtained from RNA-seq data

KIAA1429/VIRMA promotes breast cancer proliferation and migration by stabilizing m6A-modified HAS2 RNA expression in cytosol

Project description:N6-methyladenosine (m6A) is the most abundant internal RNA modification in mRNA molecules and plays important roles in multiple important biological processes including cancer development. KIAA1429/VIRMA is an important component of m6A methyltransferase complex to facilitate depositing m6A modification in RNA molecules. Here we found that KIAA1429/VIRMA was overexpressed in breast cancer patients among other m6A related enzymes. Breast cancer patients with higher KIAA1429 expression have worse survival compared with control group. In addition, KIAA1429/VIRMA protein mislocated in cytosol in breast cancer tissues and cell lines. KIAA1429/VIRMA depletion reduced breast cancer cell proliferation and migration. Mechanism studies showed that cytosolic expressed KIAA1429/VIRMA interacted with m6A reader protein IGF2BP3 and stabilized expression of m6A-modified HAS2 expression. HAS2 is downstream of KIAA1429/VIRMA to mediate breast cancer cell proliferation and migration and has positive correlation with KIAA1429/VIRMA expression in cancer patients.

VIRMA-mediated m6A modification regulates forebrain formation through facilitating ribosome biogenesis

Project description:N6-methyladenosine (m6A) modification plays crucial roles in tissue development and homeostasis. However, the mechanisms underlying cellular adaptation of m6A modification and their impact on protein synthesis machinery remain unclear. VIRMA, the largest and evolutionarily conserved core of the m6A methyltransferase complex, is highly expressed in the embryonic brain and various cancers. Here, we demonstrate that VIRMA-mediated m6A modification is essential for active ribosome biogenesis. VIRMA depletion destabilizes the entire writer complex and reduces m6A levels, leading to decreased proliferation and increased apoptosis of neural progenitor/stem cells (NPCs), ultimately causing severe forebrain developmental defects. Mechanistically, VIRMA depletion impairs ribosome biogenesis by inhibiting mRNA decay, triggering a p53-dependent stress response and compromising global protein synthesis. Importantly, these findings extend to human cancer cells, suggesting a potential conservation of this mechanism. Overall, our study reveals the critical role of m6A in adapting protein synthesis machinery during brain development and potentially in cancer.

Human breast cancer SKBr-3 cells: trastuzumab-resistant vs. parental

Project description:Human breast cancer SKBr-3 cells selected with trastuzumab for 6 month compared with parental SKBr-3 cells; Goal was to screen for microRNAs involved in development of trastuzumab resistance. Human breast cancer SKBr-3 cells were continuously cultured in the presence ofM-BM- 5M-BM-5g/ml trastuzumab for 6 months, and the resulting alive cells were regarded as trastuzumab-resistant. Total RNAs were prepared from these cells and cells cultured in parallel in control media, and were subjected to hybridization on the miRCURY LNA Array (Exiqon, version 11.0).
