ABSTRACT

Background

Cancer occurs in approximately 1:1000 pregnancies. When chemotherapy cannot be delayed until postpartum, beginning chemotherapy is based on presumed safety after organogenesis is completed during the first trimester. The safest gestational age to start chemotherapy after the first trimester is unknown.

Patients and Methods

In an observational cohort of pregnant women diagnosed and treated for cancer at multiple centers, pregnancy outcomes for the mother, and clinical outcomes for the neonate were analyzed according to the gestational age in weeks of pregnancy at first chemotherapy cycle. Outcomes including birth weight, fetal growth restriction, congenital malformations, and perinatal complications for …

The class I cyclin family is a well-studied group of structurally conserved proteins that interact with their associated cyclin-dependent kinases (Cdks) to regulate different stages of cell cycle progression depending on their oscillating expression levels. However, the role of class II cyclins, which primarily act as transcription factors and whose expression remains constant throughout the cell cycle, is less well understood. As a classic example of a transcriptional cyclin, cyclin C forms a regulatory sub-complex with its partner kinase Cdk8 and two accessory subunits Med12 and Med13 called the Cdk8-dependent kinase module (CKM). The CKM reversibly associates with the multi-subunit …
