Project description:LncRNAs play a critical role in both innate and adaptive immunity by regulating survival, differentiation, migration and cytokine production of the immune cells We found a cytoplasmic lncRNA IRENA in the TAMs, which triggered the NF-κB signaling and increased the production of pro-tumor inflammatory cytokines.
Project description:To determine the lncRNA expression profile in ectopic APC overexpressed CRC cell lines and control cells, we uesed lncRNA microArray analysis form Arraystar to examine lncRNA expression profile in ectopic APC overexpressed CRC cell lines and control cells.
Project description:The stem cell gene LIN28B was recently shown to be overexpressed in a foetal-like subgroup of juvenile myelomonocytic leukaemia. Given the involvement of LIN28B in a variety of solid paediatric cancers, we conducted a meta-analysis of LIN28B levels using publicly available gene expression data of 1361 paediatric leukaemia samples. Interestingly, this analysis revealed LIN28B overexpression in 102 childhood leukaemia patients (7.5%), suggesting oncogenic activity for LIN28B in the context of paediatric haematological diseases. As the mode of action of LIN28B during normal and malignant haematopoiesis remains largely unexplored, we subsequently analysed the transcriptional consequences of LIN28B modulation on normal and malignant haematopoietic cells and identified the long non-coding RNA (lncRNA) H19 as the first LIN28B-regulated lncRNA. K562 cells were retrovirally transduced with shRNA GN36578 against LIN28B and a shRNA-miR non-targeting control TRH1103 (both Transomic), selected with puromycin and hybridized on Agilent microarray.

Oci-AML3 cells were retrovirally transduced with MSCV-PIG-LIN28B and MSCV-PIG-empty vectors (gifts from Johua Mendel lab), selected with puromycin and hybridized on Agilent microarray.
Project description:Transcriptional profiling of human hepatoellular carcinoma (HCC) cell line: MHCC-97H comparing control untreated MHCC-97H cells with MHCC-97H cells overexpressed ROCK1 protein. Goal was to determine the effect of ROCK1 on global MHCC-97H cell mRNA and lncRNA expression. Transcriptional profiling of human hepatoellular carcinoma (HCC) cell line: MHCC-97H comparing control untreated MHCC-97H cells with MHCC-97H cells overexpressed ROCK2 protein. Goal was to determine the effect of ROCK2 on global MHCC-97H cell mRNA and lncRNA expression. Transcriptional profiling of human hepatoellular carcinoma (HCC) cell line: MHCC-97H comparing MHCC-97H cells overexpressed ROCK1 with MHCC-97H cells overexpressed ROCK2 protein. Goal was to determine the distinction of ROCK1 & 2 on global MHCC-97H cell mRNA and lncRNA expression.
