Peripheral T-cell Lymphoma (PTCL) consists of numerous distinct disease entities. With the current diagnostic criteria over a third of the cases cannot be further classified and are called "not otherwise specified" (PTCL-NOS). Using gene expression profiling (GEP) of tumors, we identified two novels PTCL-NOS molecular subgroups either characterized by high expression of GATA3 (33%), which is associated with Th2 cell differentiation, or high expression of TBX21 (49%) which regulates Th1 cell maturation. Therefore, stratifying patients for diagnosis and identifying the underlying genetic basis to improve clinical therapy becomes critical to prognosis.
First, we performed DNA copy number analysis by using …

Melanoma is the deadliest form of skin cancer, and incidence has continued to increase. Half of all melanomas have a BRAF V600E mutation and respond to MAPK pathway inhibitors, including BRAF inhibitor therapy or BRAF/MEK inhibitor combination therapy, but nearly all patients develop treatment resistance. Melanoma cell lines produce variable results as models of MAPK pathway inhibitor resistance. To better understand how the genomic similarity of a melanoma cell line to patient-derived tumors affects resistance mechanisms, differences in DNA mutations and copy-number alterations were compared between melanoma cell lines profiled by the Cancer Cell Line Encyclopedia and cutaneous melanoma tumors …
