Integrating methylome and transcriptome signatures expands the molecular classification of the pituitary tumors [RNA-seq]

Pituitary tumors (PitNETs) tumorigenesis is still not completely understood. Few studies have integrated exome, methylome, and transcriptome analyses. Taking advantage of a comprehensive phenotypic characterized Brazilian cohort, which has heterogeneous ethnic origin, we combined methylome and transcriptome analysis of the three major subtypes of surgically resectable PitNETs. Here, we included RNA-seq and basal patient / tumor data of 65 PitNETs: GH-secreting (acromegaly,n = 15), ACTH-secreting (Cushing disease, n = 7), and Non-Functioning (n = 43 PitNETs). Overall design: Retrospective cross-sectional study.
