Objective: Transitional cell carcinoma (TCC) is the most common malignant tumour of the canine urinary tract. Previously, the mutation of the BRAF gene V595E was identified in approximately 85 % of canine TCC cases by DNA sequencing of TCC tumour cells, both in frozen and paraffin-embedded tissue sections, as well as in urine. The objective of this study was to establish these methods in cytological smears and to investigate the prevalence of BRAF mutation V595E in canine TCC in our cohort of patients. Read More

X-linked myotubular myopathy (XLMTM) is a rare inherited neuromuscular disorder associated with mutations in the gene on the Xq28 region. We report a severely affected girl with XLMTM, caused by maternally inherited 661 kb Xq28 microduplication identified by chromosomal microarray analysis and confirmed also on DNA from muscle biopsy with a custom-designed X-chromosome-specific microarray. X-inactivation analysis revealed a skewed inactivation pattern on the proband's muscle biopsy. Read More

The eighth editions of the primary tumor, lymph node and metastasis classifications for breast cancer issued by the American Joint Commission of Cancer and the Union for International Cancer Control were revised in 2017. The major change made by the American Joint Commission of Cancer is to incorporate biological factors such as estrogen and progesterone receptor, human epidermal growth factor receptor 2, histological grade and multigene prognostic assays, into the staging system. Tumor biomarkers and low recurrence scores confirmed by multigene prognostic assays change the staging. Read More

There is a considerable need to identify those individuals with prostate cancer who have indolent disease. We propose that genes that control adult stem cell homeostasis in organs with slow turnover, such as the prostate, control cancer fate. One such gene, KLF4, overexpressed in murine prostate stem cells, regulates their homeostasis, blocks malignant transformation, and controls the self-renewal of tumor-initiating cells. Read More

Malignant tumors found in children are different from the ones that occur in adults. Compared to the malignancies in adults, the histological entities in pediatric patients are different and survival rates are higher among the children. Though pediatric soft tissue sarcomas are less common than leukemia and central nervous system malignancies, recognition of them is necessary to start the therapy as soon as possible. Read More

Achaete-scute homolog 1 gene (ASCL1) is a gene classifier for the proneural (PN) transcriptional subgroup of glioblastoma (GBM) that has a relevant role in the neuronal-like differentiation of GBM cancer stem cells (CSCs) through the activation of a PN gene signature. Besides prototypical ASCL1 PN target genes, the molecular effectors mediating ASCL1 function in regulating GBM differentiation and, most relevantly, subgroup specification are currently unknown. Here we report that ASCL1 not only promotes the acquisition of a PN phenotype in CSCs by inducing a glial-to-neuronal lineage switch but also concomitantly represses mesenchymal (MES) features by directly downregulating the expression of N-Myc downstream-regulated gene 1 (NDRG1), which we propose as a novel gene classifier of MES GBMs. Read More

As aldehyde dehydrogenase (ALDH) is a novel stem cell marker, increasing studies have confirmed that high ALDH activity promotes tumorigenesis and progression in cancers. Some preliminary studies have found that ALDH1A3 may play an important role in glioma malignant progression, but so far there was no conclusive conclusion. The purpose of our study was to elucidate the mechanisms by which ALDH1A3 regulated in glioma and to provide practical tools for clinical application. Read More
