Automated image analysis DNA cytometry in testicular cancer

1994

The value of automated DNA cytometry for differentiation of testis cancer was evaluated in 54 seminomas, 13 HCG-positive seminomas, and 48 embryonal carcinomas. Slices of paraffin embedded tissue were enzymatically digested and stained with Feulgen SITS after fixation on glass slides. Automated DNA cytometry was performed with a Modular Image Analysis Computer (MIAC). DNA histogram phenotpye and computed DNA indices were correlated with the different tumor types. The ratio of hypertriploid to hypotriploid increased from HCG-positive seminoma over embryonal carcinoma to seminoma. The following mathematical DNA indices were found to correlate with tumor type: mean ploidy, 2c deviation index, …

A novel mutation of gene CBFA1/RUNX2 in cleidocranial dysplasia.

2007

Cleidocranial dysplasia (CCD) is an autosomal dominant skeletal dysplasia characterised by abnormal clavicles, patent sutures and fontanelles, supernumerary teeth, short stature, and a variety of other skeletal changes. The disease gene is CBFA1/RUNX2, which is mapped to chromosome 6p21. Inactivation of the CBFA1/RUNX2 gene by mutations is involved in the skeletal defects that occur in patients with CCD. CBFA1/RUNX2 controls the differentiation of precursor cells into osteoblasts and is essential for membranous as well as endochondral bone formation. In this study of a 14-yr-old boy with typical CCD phenotype, the authors found a novel CBFA1/RUNX2 gene mutation. All of the amplified segment…

Characterization of conservatively resected renal tumors using automated image analysis DNA cytometry

1991

The DNA histograms of 57 conservatively resected renal tumors were studied using automated image analysis DNA cytometry (Leytas II). Forty-nine of the analyzed tumors were renal cell carcinomas, six were oncocytomas, one was an angiomyolipoma, and one was a renal cell adenoma. On the basis of their DNA histograms, diploid, tetraploid, and aneuploid tumors could be distinguished. Aneuploid tumors could be subtyped further according to the DNA content of the stem cell line as hyperdiploid, hypertriploid, or hypertetraploid. Eight of the tumors were characterized by a combination of diploid and hypertriploid stem cell lines. During a mean follow-up of 5 years, only the two patients with a pure…
