Differences in the pattern and regulation of mineral deposition in human cell lines of osteogenic and non-osteogenic origin (2011)
Journal Article

Bone marrow-derived mesenchymal stem cells (MSCs) are widely used as a cellular model of bone formation, and can mineralize in vitro in response to osteogenic medium (OM). It is unclear, however, whether this property is specific to cells of mesenchy...

Oxr1 Is Essential for Protection against Oxidative Stress-Induced Neurodegeneration (2011)
Journal Article

Oxidative stress is a common etiological feature of neurological disorders, although the pathways that govern defence against reactive oxygen species (ROS) in neurodegeneration remain unclear. We have identified the role of oxidation resistance 1 (Ox... Read More about Oxr1 Is Essential for Protection against Oxidative Stress-Induced Neurodegeneration.

Expression of thioredoxin system and related peroxiredoxin proteins is associated with clinical outcome in radiotherapy treated early stage breast cancer (2011)

Calpastatin is associated with lymphovascular invasion in breast cancer (2011)
Journal Article

Metastasis of breast cancer is a major contributor to mortality. Histological assessment of vascular invasion (VI) provides important prognostic information and demonstrates that VI occurs predominantly via lymphatics in breast cancer. We sought to e...

The calpain system and cancer (2011)
Journal Article

The calpains are a conserved family of cysteine proteinases that catalyse the controlled proteolysis of many specific substrates. Calpain activity is implicated in several fundamental physiological processes, including cytoskeletal remodelling, cellu... Read More about The calpain system and cancer.

Calpain-1 expression is associated with relapse-free survival in breast cancer patients treated with trastuzumab following adjuvant chemotherapy (2011)
Journal Article

The calpain family, and their endogenous inhibitor calpastatin, has been implicated in cancer progression, and recent in vitro data have indicated a role in trastuzumab resistance. The aims of our study were to examine expression levels of calpastati...

Redox Protein Expression Predicts Radiotherapeutic Response in Early-Stage Invasive Breast Cancer Patients (2011)
Journal Article

Purpose Early-stage invasive breast cancer patients have commonly undergone breast-conserving surgery and radiotherapy. In a large majority of these patients, the treatment is effective; however, a proportion will develop local recurrence. Deregul...

Protein flexibility directs DNA recognition by the papillomavirus E2 proteins (2010)
Journal Article

Although DNA flexibility is known to play an important role in DNA–protein interactions, the importance of protein flexibility is less well understood. Here, we show that protein dynamics are important in DNA recognition using the well-characterized... Read More about Protein flexibility directs DNA recognition by the papillomavirus E2 proteins.

DNA compaction by the higher-order assembly of PRH/Hex homeodomain protein oligomers (2010)
Journal Article

Protein self-organization is essential for the establishment and maintenance of nuclear architecture and for the regulation of gene expression. We have shown previously that the Proline-Rich Homeodomain protein (PRH/Hex) self-assembles to form oligom... Read More about DNA compaction by the higher-order assembly of PRH/Hex homeodomain protein oligomers.

In situ subcellular fractionation of adherent and non-adherent mammalian cells (2010)
Journal Article

Protein function is intimately coupled to protein localization. Although some proteins are restricted to a specific location or subcellular compartment, many proteins are present as a freely diffusing population in free exchange with a sub-population...

PRH/Hex controls cell survival through coordinate transcriptional regulation of vascular endothelial growth factor signaling (2010)
Journal Article

The proline-rich homeodomain protein (PRH) plays multiple roles in the control of gene expression during embryonic development and in the adult. Vascular endothelial growth factor (VEGF) is a mitogen that stimulates cell proliferation and survival vi...

AF4 Is a Critical Regulator of the IGF-1 Signaling Pathway during Purkinje Cell Development (2009)
Journal Article

Deregulation of the insulin-like growth factor 1 (IGF-1) signaling pathway is a recurrent finding in mouse models and human patients with cerebellar ataxia and thus represents a common pathological cascade in neuronal cell death that may be targeted...

The human papillomavirus E7-E2 interaction mechanism in vitro reveals a finely turned system for modulating available E7 and E2 proteins (2009)
Journal Article

Transcription of the human papillomavirus E7 oncoprotein is negatively controlled by the viral E2 protein, and loss of this repression leads to irreversible transformation and carcinogenesis. Here we show that interaction of the HPV16 E7 protein with...

CK2 phosphorylation of the PRH/Hex homeodomain functions as a reversible switch for DNA binding (2009)
Journal Article

The proline-rich homeodomain protein (PRH/Hex) regulates transcription by binding to specific DNA sequences and regulates mRNA transport by binding to translation initiation factor eIF4E. Protein kinase CK2 plays multiple roles in the regulation of g... Read More about CK2 phosphorylation of the PRH/Hex homeodomain functions as a reversible switch for DNA binding.

The regulation of cell proliferation by the papillomavirus early proteins (2009)
Journal Article

The human papillomavirus (HPV) E6 and E7 oncogenes have direct effects on host cell proliferation. The viral E2 protein regulates transcription of E6 and E7 and thereby has an indirect effect on cell proliferation. In HPV-induced tumours, misappropri...
