Inhibition of Intimal Thickening By PRH (Proline-Rich Homeodomain) in Mice (2023)
Journal Article

Background: Late vein graft failure is caused by intimal thickening resulting from endothelial cell (EC) damage and inflammation which promotes vascular smooth muscle cell (VSMC) dedifferentiation, migration, and proliferation. Nonphosphorylatable PR... Read More about Inhibition of Intimal Thickening By PRH (Proline-Rich Homeodomain) in Mice.

Biomolecular Condensation of the Human Papillomavirus E2 Master Regulator with p53: Implications in Viral Replication (2022)
Journal Article

p53 exerts its tumour suppressor activity by modulating hundreds of genes and it can also repress viral replication. Such is the case of human papillomavirus (HPV) through targeting the E2 master regulator, but the biochemical mechanism is not known....

Blood platelets stimulate cancer extravasation through TGFβ-mediated downregulation of PRH/HHEX (2020)
Journal Article

Cancer cells go through a process known as epithelial–mesenchymal transition (EMT) during which they acquire the ability to migrate and invade extracellular matrix. Some cells also acquire the ability to move across a layer of endothelial cells to en...

A runaway PRH/HHEX-Notch3 positive feedback loop drives cholangiocarcinoma and determines response to CDK4/6 inhibition (2019)
Journal Article

Aberrant Notch and Wnt signalling are known drivers of cholangiocarcinoma (CCA) but the underlying factors that initiate and maintain these pathways are not known. Here we show that the PRH/HHEX transcription factor forms a positive transcriptional f...

Signaling networks in cholangiocarcinoma: molecular pathogenesis, targeted therapies and drug resistance (2019)
Journal Article

Cholangiocarcinoma (CCA) is a deadly disease. While surgery may attain cure in a minor fraction of cases, therapeutic options in either the adjuvant or advanced setting are limited. The possibility of advancing the efficacy of therapeutic approaches... Read More about Signaling networks in cholangiocarcinoma: molecular pathogenesis, targeted therapies and drug resistance.

CX-4945 induces methuosis in cholangiocarcinoma cell lines by a CK2-independent mechanism (2018)
Journal Article

Cholangiocarcinoma is a disease with a poor prognosis and increasing incidence and hence there is a pressing unmet clinical need for new adjuvant treatments. Protein kinase CK2 (previously casein kinase II) is a ubiquitously expressed protein kinase...

Phosphorylation of PRH/HHEX by Protein Kinase CK2 regulates cell proliferation and cell migration in diverse cell types (2018)
Book Chapter

Disruption of the regulatory mechanisms that control cell proliferation and cell migration results in multiple disease states including cancer and leukemia. The Proline-Rich Homeodomain protein (PRH)/haematopoietically expressed homeobox protein (HHE...

Protein kinase CK2 inhibition suppresses neointima formation via a proline-rich homeodomain-dependent mechanism (2017)
Journal Article

Neointimal hyperplasia is a product of VSMC replication and consequent accumulation within the blood vessel wall. In this study, we determined whether inhibition of protein kinase CK2 and the resultant stabilisation of proline-rich homeodomain (PRH)...

The enigmatic origin of papillomavirus protein domains (2017)
Journal Article

Almost a century has passed since the discovery of papillomaviruses. A few decades of research have given a wealth of information on the molecular biology of papillomaviruses. Several excellent studies have been performed looking at the long- and sho... Read More about The enigmatic origin of papillomavirus protein domains.

Proline-rich homeodomain protein (PRH/HHEX) is a suppressor of breast tumour growth (2017)
Journal Article

Breast tumours progress from hyperplasia to ductal carcinoma in situ (DCIS) and invasive breast carcinoma (IBC). PRH/HHEX (Proline Rich Homeodomain/Haematopoietically expressed homeobox) is a transcription factor that displays both tumour suppressor...

CK2 abrogates the inhibitory effects of PRH/HHEX on prostate cancer cell migration and invasion and acts through PRH to control cell proliferation (2017)
Journal Article

PRH/HHEX (Proline Rich Homeodomain protein/Haematopoietically-Expressed Homeobox protein) is a transcription factor that controls cell proliferation, cell differentiation and cell migration.
