Project description:To assess expression of mtDNA genes in the canine transmissible venereal tumour (CTVT), biopsy tissue samples from 33 CTVT cases were subjected to total RNA extraction, and stranded RNA sequencing libraries generated with the Ribo-Zero ribosomal RNA removal kit (insert size 100–300 bp) were sequenced using 75-bp paired-end sequencing reads on an Illumina HiSeq4000 instrument. Gene transcript abundance was quantified using the Salmon software (v0.8.2).
Project description:The canine transmissible veneral tumour (CTVT) is one of the few known clonally transmissible cancers in nature. CTVT regresses spontaneously or after a single treatment with vincristine, however we know little of the mechanisms. To understand CTVT regression, we performed transcriptional analyses on serial biopsies of regressing and non-regressing CTVT, aiming to identify the likely drivers of CTVT regression.

To understand CTVT regression, we performed methylome analyses on serial biopsies of regressing and non-regressing CTVT, aiming to identify the likely drivers of CTVT regression.

Project description:Mesenchymal stem cells (MSCs) are cells with high regenerative and immunosuppressive capacity that are known to be very potent donors of functional mitochondria to all surrounding cells, including immune cells. As metabolism shapes immune cell response and phenotype, mitochondrial transfer might be one of the main immunosuppressive mechanisms used by stem cells. However, the precise mechanism underlying horizontal mitochondrial transfer and its effect on some cell populations has yet to be discovered. In our project, we have shown that MSCs transfer mitochondria to B lymphocytes less efficiently in comparison to other immune populations. To describe the effect of mitochondrial transfer on activated B lymphocytes, MSCs were co-cultivated with B lymphocytes which were activated prior to co-cultivation. Then B cell acceptors and non-acceptors of mitochondria were sorted for further RNA isolation and the performance of bulk RNA-seq.
