BACKGROUND The Hippo signaling pathway, a highly conserved cell signaling system, exists in most multicellular organisms and regulates cell proliferation, differentiation, and apoptosis. It has been reported that the members of Hippo signaling are expressed in mammalian ovaries, but the exact functions of this pathway in primordial follicle development remains unclear. METHODS To analyze the ...

Ski, the transforming protein of the avian Sloan-Kettering retrovirus, inhibits transforming growth factor-β (TGF-β)/Smad signaling and displays both pro-oncogenic and anti-oncogenic activities in human cancer. Inhibition of TGF-β signaling is likely responsible for the pro-oncogenic activity of Ski. We investigated the mechanism(s) underlying the tumor suppressor activity of Ski and found that...

Epigenetic of hippo pathway genes play crucial roles of signalling pathways in regulating organ size, cell proliferation and cell death in human. Our study focused on identifying differential methyla-tion patterns in bone, breast and prostate cancer cell lines. We performed methylation analysis of the CpG island promoter in these cells by methylation-specific PCR. Our data indicates that methyl...

Cancer biomarkers with a strong predictive power for diagnosis/prognosis and a potential to be therapeutic targets have not yet been fully established. Here we employed a loss-of-function screen in glioblastoma (GBM), an infiltrative brain tumor with a dismal prognosis, and identified 20 survival kinase genes (SKGs). Survival analyses using The Cancer Genome Atlas (TCGA) datasets revealed that ...

InDrosophila, the Hippo-signaling pathway is awell-known orchestrator of organismal size. Probing whether these mechanisms also mould organogenesis in mammals, James Martin and colleagues disrupted multiple Hippo pathway components in the developing mouse heart. These targets for conditional knockout include the MST kinases (the mammalian Hippo homologues), Salvador (a scaffold protein that bin...

Numerical aberration of the centrosome results in chromosome missegregation, eventually leading to chromosomal instability, a hallmark of human tumor malignancy. Large tumor suppressors 1 and 2 (Lats1 and Lats2) are central kinases in the Hippo pathway and regulate development and tumorigenesis by coordinating the balance between cell proliferation and apoptosis. Importantly, Lats1 and Lats2 al...

Pseudogenes have been considered as non-functional transcriptional relics of human genomic for long time. However, recent studies revealed that they play a plethora of roles in diverse physiological and pathological processes, especially in cancer, and many pseudogenes are transcribed into long noncoding RNAs and emerging as a novel class of lncRNAs. However, the biological roles and underlying...

BACKGROUND The Hippo signaling pathway plays fundamental roles in stem cell maintenance in a variety of tissues and has thus implications for stem cell biology. Key components of this recently discovered pathway have been shown to be associated with primordial follicle activation. However, whether the Hippo signaling pathway plays a role in the development of Ovarian Germline Stem Cells (OGSCs)...
