Project description:We found that YTHDF2 has lower expression in GC tissues and GC cells, and promotes the growth, migration and invasion of GC cells. In addition, the analysis of clinical data found that the expression level of YTHDF2 was closely related to the stage of GC and the survival of patients with GC. RNA-seq showed that overexpression of YTHDF2 significantly reduced protein expression in the FOXC2 (Forkhead box protein C2, FOXC2) signaling pathway.

Project description:Investigation of whole genome gene expression level changes in a colorectal cancer cell line SW480 expressing FOXC2, compared to the pBabe control cells. Genes associated with metastasis regulated by FOXC2 in colorectal cancer were analysed. The role of FOXC2 in breast cancer metastasis are further described in Mani SA, Yang J et al. Mesenchyme Forkhead 1 (FOXC2) plays a key role in metastasis and is associated with aggressive basal-like breast cancers. PNAS 2007; 104: 10069-10074 . A six chip study using total RNA recovered from three separate cultures of SW480/pBabe and three separate cultures of SW480/FOXC2. Each chip measures the expression level of 45033 genes from SW480/pBabe or SW480/FOXC2.
Project description:Foxc1 and Foxc2 are highly expressed in adult podocytes. To bypass embryonic lethality of Foxc1 and Foxc2 KO, mice ubiquitously expressing inducible-Cre (ROSA26-CreERT2) were mated with floxed-Foxc1 and floxed-Foxc2 mice. We used microarrays to detail effects of deletions of Foxc1 and Foxc2 on podocyte gene expression profiles in adult podocyte in vivo and in vitro.
Project description:To determine gene expression changes in vasculogenic mimicry competent human breast cancer cells with loss of FOXC2 we performed RNA-seq of MDA-MB-231 cells with FOXC2 knockdown.
Project description:We used microarrays to investigate the transcription profile of FOXC2 expression in a human mammary epithelial cell line. HMLER cells were infected with either a control vector or a retroviral vector expressing FOXC2.
Project description:To study the role of the protein YTHDF2 during female gametogenesis, its gene was conditionally deleted in oocytes. Total RNA samples from YTHDF2 deficient GV and MII oocytes (and control oocytes) were subjected to array profiling.
Project description:N6-methyladenosine (m6A) in messenger RNA (mRNA) regulates immune cells in homeostasis and in response to infection and inflammation. The function of the m6A reader YTHDF2 in the tumor microenvironment (TME) in these contexts has not been explored. We discovered that the loss of YTHDF2 in regulatory T (Treg) cells reduces tumor growth in mice. Deletion of Ythdf2 in Tregs does not affect peripheral immune homeostasis but leads to increased apoptosis and impaired suppressive function of Treg cells in the TME. Elevated tumor necrosis factor (TNF) signaling in the TME promotes YTHDF2 expression, which in turn regulates NF-κB signaling by accelerating the degradation of m6 A-modified transcripts that encode NF-κB-negative regulators. This TME-specific regulation of Treg by YTHDF2 points to YTHDF2 as a potential target for anti-cancer immunotherapy, where intratumoral Treg cells can be targeted to enhance anti-tumor immune response while avoiding Treg cells in the periphery to minimize undesired inflammations.
