Project description:The rectal cancer patient data set consists of 10 patients from a clinical study at the Surgery department of the University Medical Center Göttingen collected over a longer time. Patients were chosen based on the follow-up time and development of a distant metastasis. First a balanced sample size of five versus five patients with and without a metastatic event was chosen. This needed to be changed to six versus four. Two conditions of rectal cancer patient data separates by the event of distant metastasis: 1. good prognosis, no event (4 samples), 2. bad prognosis, event (6 samples) Single-end sequencing on a Illumina HiSeq 200 machine with the standard total_RNA protocol with 50 base pairs read length was used

Project description:The presence or absence of lymph node metastasis plays a major role in the prediction of prognosis and subsequent patient management. However, good proportion of patients who display lymph node positivity remain disease free for 3 years or more, after the initial treatment, while a third of those who were lymph node negative at presentation, develop distant metastasis within the same period. We performed gene expression profiling on a cohort Indian breast cancer patients followed up for a period of 3-5 years and in comparison with a previously published Caucasian cohort data, we identified gene signatures that are associated with distant metastasis. This association was irrespective of the hormone receptor status. Our results show that the genes that signify immune system development and response are repressed, while factors for DNA replication are up regulated in patients who develop distant metastasis. A large number of genes encoding proteins involved in the mitotic spindle formation that belong to the TRIM28 protein network, are differentially regulated in the metastatic tumors. Also, there was a significant overlap of genes reported in a mouse model of bone metastasis, with patients who developed bone metastasis in our cohort. In conclusion, we present for the first time probable gene signatures that correlate with distant metastasis in breast cancer patients irrespective of nodal or hormone receptor status

Project description:We collected unique sets of tissue fractions from each patient: solid metastatic tissue (Tumor fraction), liquid bone marrow at the site of the metastasis (Involved), as well as liquid bone marrow from a vertebral body distant from the tumor site (Distal). This allowed for a comparison within the same individual, controlling for inter-individual variation. Bone marrow samples from patients undergoing hip replacement surgery (Benign) served as a non-malignant comparator group. The transcriptional composition of all samples was assessed using single-cell RNA-seq (scRNA-seq).

Project description:In lobular breast cancer, metachronous distant metastasis may become evident many years after primary tumor diagnosis and often affect the ovary. Little is known about tumor dormancy and intratumoral heterogeneity of DNA methylation in metastasis from lobular breast cancer. In this exploratory analysis, DNA methylation patterns were studied in six spacially separated regions of an ovarian metastasis from lobular breast cancer.

Project description:During pancreatic cancer progression, heterogeneous subclonal populations evolve in the primary tumor that possess differing capacities to metastasize and cause patient death. However, the genetics of metastasis reflects that of the primary tumor, and PDAC driver mutations arise early. This raises the possibility than an epigenetic process could be operative late. Using an exceptional resource of paired patient samples, we found that different metastatic subclones from the same patient possessed remarkably divergent malignant properties and global epigenetic programs. Global reprogramming was targeted to thousands of large chromatin domains across the genome that collectively specified malignant divergence. This was maintained by a metabolic shift within the pentose phosphate pathway, independent of KRAS driver mutations. Analysis of paired primary and metastatic tumors from multiple patients uncovered substantial epigenetic heterogeneity in primary tumors, which resolved into a terminally reprogrammed state in metastatic lesions. This supports a model whereby driver mutations accumulate early to initiate pancreatic tumorigenesis, followed by a period of subclonal evolution that generates sufficient intra-tumor heterogeneity for selection of epigenetic programs that may increase fitness during malignant progression and metastatic spread. To map the epigenomic landscape of pancreatic cancer progression as it evolves within patients. BS-Seq of 4 patients (A13, A38, A124 and A125). Patient A38 included local peritoneal metastasis and 2 distant metastsis (liver and lung mets). Patient A13 included 2 primary tumors and 1 distant lung metastasis. Each sample has been done with replicates. Patient A124 included 2 primary tumors and 1 normal pancreas.
