Adult T-cell leukaemia-lymphoma (ATL) is a mature malignancy, with more than 50% of cases showing cutaneous involvement. Patients cutaneous-type ATL (cATL) in the indolent type (i.e., favourable chronic or smouldering type) can usually be managed by watchful waiting and they are primarily treated skin-directed therapies until disease progresses to acute crisis, multiple tumours considered intra...

Correction to LaClair et al.: Treatment with bexarotene, a compound that increases apolipoprotein-E, provides no cognitive benefit in mutant APP/PS1 mice. Molecular Neurodegeneration 2013 8:18. After publication of this work [1], we were alerted to an error in the reported cohort size used for the Radial Arm Water Maze as referenced from [2]. The correct cohort size reported in [2] is n=8-13 fo...

PURPOSE Retinoic acid (RA) treatment has been used for redifferentiation of metastatic thyroid cancer with loss of radioiodine uptake. The aim of this study was to improve the understanding of RA resistance and investigate the role of bexarotene in thyroid cancer cells. EXPERIMENTAL DESIGN A model of thyroid cancer cell lines with differential response to RA was used to evaluate the biologica...

Apolipoprotein E4 (apoE4), the most prevalent genetic risk factor for Alzheimer's disease (AD), is less lipidated than its corresponding AD-benign form, apoE3, and it has been suggested that the pathological effects of apoE4 are mediated by lipid-related mechanisms. ATP-binding cassette transporters A1 and G1 (ABCA1 and ABCG1, respectively) are the most important apoE-lipidating proteins. The e...

The rexinoid bexarotene represses cyclin D1 by causing its proteasomal degradation. The epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) erlotinib represses cyclin D1 via different mechanisms. We conducted a preclinical study and 2 clinical/translational trials (a window-of-opportunity and phase II) of bexarotene plus erlotinib. The combination repressed growth and cyclin...

Mycosis fungoides is a low-grade lymphoproliferative disorder of skin-homing CD4+ lymphocytes that may produce patches, plaques, tumors, erythroderma, and, ultimately, systemic dissemination. Treatment selection is generally guided by institutional experience, patient preference, and toxicity profile, as data from phase III clinical trials are limited. Effective topical treatments currently inc...

Alzheimer's disease (AD) is associated with impaired clearance of β-amyloid (Aβ) from the brain, a process normally facilitated by apolipoprotein E (apoE). ApoE expression is transcriptionally induced through the action of the nuclear receptors peroxisome proliferator-activated receptor gamma and liver X receptors in coordination with retinoid X receptors (RXRs). Oral administration of the RXR ...

UBE1L is the E1-like ubiquitin-activating enzyme for the IFN-stimulated gene, 15-kDa protein (ISG15). The UBE1L-ISG15 pathway was proposed previously to target lung carcinogenesis by inhibiting cyclin D1 expression. This study extends prior work by reporting that UBE1L promotes a complex between ISG15 and cyclin D1 and inhibited cyclin D1 but not other G1 cyclins. Transfection of the UBE1L-ISG1...

Clinically relevant animal models of mammary carcinogenesis are crucial for the development and evaluation of new breast cancer chemopreventive agents. The neu-induced retroviral rat mammary carcinogenesis model is based on the direct in situ transfer of the activated neu oncogene into the mammary epithelium using a replication-defective retroviral vector. The resulting mammary carcinomas in in...
