Project description:Isolation and characterization of two recently isolated Novosphingobium oxfordensis sp. nov. and Novosphingobium mississippiensis sp. nov. strains from soil, with LCMS and genome-based investigation of their glycosphingolipid productions
Project description:Toxoplasma gondii is an apicomplexan parasite infecting human and animals, causing huge health concerns and economic losses. However, it is unclear about the exact mechanism of T.gondii tachyzoite infected macrophage and macrophage resisted T.gondii, especially for local isolates such as TgHB1 isolated in China. Our study focused on the transcriptional difference of pig alveolar macrophages (3D4/21) infected with china isolated TgHB1 compared to TgRH and TgME49 toxoplasma gondii standard strains.
Project description:We found that a novel gene BC094916 mRNA significantly decreased in plasma cells. Because of plasmablast-like, mus musculus myeloma SP 2/0 cell line was selected to test the effect of BC094916 overexpression on plasmablast/plasma cells. BC094916 cDNA (General Biosystems, Anhui, China) was cloned into lentiviral vector LV122 or LV201 (Fugene Corp., Guangzhou, China) to generate BC094916 and BC094916-EGFP fusion protein, respectively. BC094916-expressing LV122 was then transfected into SP 2/0 cells, and stable transfectants were identified by drug selection (Puromycin, Sigma, 10 μg/ml). BC094916 overexpression suppressed SP 2/0 cell proliferation by inducing cell apoptosis. Importantly, BC094916 overexpression effectively suppressed tumor progression in the SP 2/0 xenograft mouse model. In addition, we found that BC094916 is a suppressive transcriptional factor. To verify its target genes, we determined mRNA profiles in BC094916-overexpressed and vector-transduced SP 2/0 cells by RNA-seq. RNA-seq was done with an Illumina HiSeq 2500 instrument at GENEWIZ, Suzhou, China.
Project description:We found that a novel gene Gm614 mRNA significantly changed in plasma cells. Because of plasmablast-like, Mus musculus myeloma SP 2/0 cell line was selected to test the effect of Gm614 overexpression on plasmablast/plasma cells. Gm614 cDNA (General Biosystems, Anhui, China) was cloned into lentiviral vector LV201 (Fugene Corp., Guangzhou, China) to generate Gm614 protein. Gm614-expressing LV201 was then transfected into SP 2/0 cells, and stable transfectants were identified by drug selection (Puromycin, Sigma, 10 μg/ml). To identify the effect of Gm614 overexpression on gene expression, we determined mRNA profiles in Gm614-overexpressed and vector-transduced SP 2/0 cells by RNA-seq. RNA-seq was done with an Illumina HiSeq 2500 instrument at GENEWIZ, Suzhou, China.
