HOXA7, HOXA9, and HOXA10 are differentially expressed in clival and sacral chordomas. Sci Rep 2017; 7:2032.

Abstract
Chordomas are rare tumours of the bone arising along the spine from clivus to sacrum. We compared three chordoma cell lines of the clivus region including the newly established clivus chordoma cell line, U-CH14, with nine chordoma cell lines originating from sacral primaries by morphology, on genomic and expression levels and with patient samples from our chordoma tissue bank. Clinically, chordomas of the clivus were generally smaller in size at presentation and patients with sacral chordomas had more metastases and more often recurrent disease. All chordoma cell lines had a typical physaliphorous morphology and expressed brachyury, S100-protein and cytokeratin. By expression analyses we detected differentially expressed genes in the clivus derived cell lines as compared to the sacral cell lines. Among these were HOXA7, HOXA9, and HOXA10 known to be important for the development of the anterior-posterior body axis. These results were confirmed by qPCR. Immunohistologically, clivus chordomas had no or very low levels of HOXA10 protein while sacral chordomas showed a strong nuclear positivity in all samples analysed. This differential expression of HOX genes in chordomas of the clivus and sacrum suggests an oncofetal mechanism in gene regulation linked to the anatomic site.

Abstract
Recent decades have witnessed the publication of numerous studies reporting alterations in the genome and transcriptome of head and neck squamous cell carcinoma (HNSCC). Currently, the utilisation of these alterations as biomarkers and targets for therapy is limited and new, useful molecular characteristics are being sought. Many of the published HNSCC gene expression profiles demonstrate alterations in the expression of HOX genes. These are a family of Homeobox-containing genes which are involved in developmental patterning and morphogenesis in the embryo, and which are often aberrantly expressed in cancer. The 39 HOX genes found in the human genome are arranged in four paralogous groups at different chromosomal loci. These control a wide range of cellular processes, including proliferation and migration, which are relevant in the context of cancer development. In this review article, we will outline the biology of HOX genes in relation to cancer and summarise the accumulating evidence for their role in the development of HNSCC and the possibility that they could be a therapeutic target in this malignancy. We will also identify areas where our current understanding is weak to focus future work and appraise the ongoing strategies for pharmacological intervention.

BIOCHIMICA ET BIOPHYSICA ACTA-BIOMEMBRANES 2015; 1848:2493-501. [PMID: 25922224 DOI: 10.1016/j.bbamem.2015.04.013] [Citation(s) in RCA: 67] [Impact Index Per Article: 7.4] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Received: 08/04/2014] [Revised: 04/13/2015] [Accepted: 04/20/2015] [Indexed: 11/16/2022]
Abstract
Voltage-gated sodium channels are abnormally expressed in tumors, often as neonatal isoforms, while they are not expressed, or only at a low level, in the matching normal tissue. The level of their expression and their activity is related to the aggressiveness of the disease and to the formation of metastases. A vast knowledge on the regulation of their expression and functioning has been accumulated in normal excitable cells. This helped understand their regulation in cancer cells. However, how voltage-gated sodium channels impose a pro-metastatic behavior to cancer cells is much less documented. This aspect will be addressed in the review. This article is part of a Special Issue entitled: Membrane channels and transporters in cancers.

Abstract
OBJECTIVE Inhibitor of differentiation-3 (Id3) has been implicated in promoting angiogenesis, a key determinant of high-fat diet (HFD)-induced visceral adiposity. Yet the role of Id3 in HFD-induced angiogenesis and visceral adipose expansion is unknown. METHODS AND RESULTS Id3(-/-) mice demonstrated a significant attenuation of HFD-induced visceral fat depot expansion compared to wild type littermate controls. Importantly, unlike other Id proteins, loss of Id3 did not affect adipose depot size in young mice fed chow diet or differentiation of adipocytes in vitro or in vivo. Contrast enhanced ultrasound revealed a significant attenuation of visceral fat microvascular blood volume in HFD-fed mice null for Id3 compared to wild type controls. HFD induced Id3 and VEGFA expression in the visceral stromal vascular fraction and Id3(-/-) mice had significantly lower levels of VEGFA protein in visceral adipose tissue compared to wild type. Furthermore, HFD-induced VEGFA expression in visceral adipose tissue was completely abolished by loss of Id3. Consistent with this effect, Id3 abolished E12-mediated repression of VEGFA promoter activity. CONCLUSIONS Results identify Id3 as an important regulator of HFD-induced visceral adipose VEGFA expression, microvascular blood volume, and depot expansion. Inhibition of Id3 may have potential as a therapeutic strategy to limit visceral adiposity.

Abstract
HOX (homeobox) genes encode homeodomain-containing transcription factors critical to development, differentiation, and homeostasis. Their dysregulation has been implicated in a variety of cancers. Previously, we showed that a subset of genes of the HOXC cluster is upregulated in primary prostate tumors, lymph node metastases, and malignant prostate cell lines. In the present study, we show that HOXC8 inhibits androgen receptor (AR)-mediated gene induction in LNCaP prostate cancer cells and HPr-1 AR, a nontumorigenic prostate epithelial cell line. Mechanistically, HOXC8 blocks the AR-dependent recruitment of the steroid receptor coactivators steroid receptor coactivator-3 (SRC-3), and CREB binding protein to the androgen-regulated prostate-specific antigen gene enhancer and inhibits histone acetylation of androgen-regulated genes. Inhibition of androgen induction by HOXC8 is reversed upon expression of SRC-3, a member of the SRC/p160 steroid receptor cofactor family. Coimmunoprecipitation studies show that HOXC8 expression inhibits the hormone-dependent interaction of AR and SRC-3. Finally, HOXC8 expression increases invasion in HPr-1 AR nontumorigenic cells. These data suggest a complex role for HOXC8 in prostate cancer, promoting invasiveness while inhibiting AR-mediated gene induction at androgen response element-regulated genes associated with differentiated function of the prostate. A greater understanding of HOXC8 actions in the prostate and its interactions with androgen signaling pathways may elucidate mechanisms driving the onset and progression of prostate cancer.

Abstract
In both the UK and USA more people die of lung cancer than any other type of cancer. Lung cancer's high mortality rate is also reflected on a global scale, with lung cancer accounting for more than 1 million deaths per year. In tissues with ordered structure such a lung epithelia, it is likely that the cancers have their origins in normal adult stem cells, and then the tumours themselves are maintained by a population of malignant stem cells - so-called cancer stem cells. This review examines both these postulates in animal models and in the clinical setting, noting that stem cell niches appear to foster tumour development, and that drug resistance can often be attributed to malignant cells with stem cell properties.

Abstract
BACKGROUND Outcomes of patients with lung adenocarcinomas can be predicted to some extent from the pathologic stage (p-stage). Although all attempts are made to fully remove cancer lesions, still a number of p-stage I patients without metastatic disease at the time of surgery develop recurrences and die of cancer. It is thus very important to identify p-stage I patients who are at risk of recurrence. METHODS Previously, using microdissected samples, we identified metastasis-related genes. Using real-time reverse-transcriptase polymerase chain reaction analysis, we investigated the transcriptional levels of the top metastasis-related genes using 96 independent test lung adenocarcinoma samples and investigated their correlations with the prognosis. RESULTS AND CONCLUSIONS We document evidence that p-stage I patients with HOXB2 up-regulation have a worse prognosis than those with HOXB2 down-regulation (p = 0.0065), whereas the HOXB2 status has no prognostic significance for p-stage II-IV patients. Comparing tumors and corresponding normal lung tissue, we confirmed HOXB2 up-regulated lesions to have much higher HOXB2 expression than the corresponding normal tissue. Confirmation with a larger number of samples is needed, with further research to clarify the molecular functions of HOXB2.

Abstract
The HOM-C clustered prototype homeobox genes of Drosophila, and their counterparts, the HOX genes in humans, are highly conserved at the genomic level. These master regulators of development continue to be expressed throughout adulthood in various tissues and organs. The physiological and patho-physiological functions of this network of genes are being avidly pursued within the scientific community, but defined roles for them remain elusive. The order of expression of HOX genes within a cluster is co-ordinated during development, so that the 3' genes are expressed more anteriorly and earlier than the 5' genes. Mutations in HOXA13 and HOXD13 are associated with disorders of limb formation such as hand-foot-genital syndrome (HFGS), synpolydactyly (SPD), and brachydactyly. Haematopoietic progenitors express HOX genes in a pattern characteristic of the lineage and stage of differentiation of the cells. In leukaemia, dysregulated HOX gene expression can occur due to chromosomal translocations involving upstream regulators such as the MLL gene, or the fusion of a HOX gene to another gene such as the nucleoporin, NUP98. Recent investigations of HOX gene expression in leukaemia are providing important insights into disease classification and prediction of clinical outcome. Whereas the oncogenic potential of certain HOX genes in leukaemia has already been defined, their role in other neoplasms is currently being studied. Progress has been hampered by the experimental approach used in many studies in which the expression of small subsets of HOX genes was analysed, and complicated by the functional redundancy implicit in the HOX gene system. Attempts to elucidate the function of HOX genes in malignant transformation will be enhanced by a better understanding of their upstream regulators and downstream target genes.
