A new species in the Hieracium lycopifolium agg. (Asteraceae) from the Western Carpathians

open access: yesActa Societatis Botanicorum Poloniae, 2011
Hieracium zajacii Szeląg is described from the Vel'ká Fatra Mts in Slovakia. It is the first representative of H. lycopifolium agg. to be found in the Carpathians. The new species is tetraploid (2n = 36) and reproduces apomictically.

Inference of plasmid copy number mean and noise from single cell gene expression data

open access: yes, 2010
Plasmids are extra-chromosomal DNA molecules which code for their own replication. We previously reported a setup using genes coding for fluorescent proteins of two colors that allowed us, using a simple model, to extract the plasmid copy number noise in

Methylation biomarkers can distinguish pleural mesothelioma from healthy pleura and other pleural pathologies

open access: yesMolecular Oncology, EarlyView.
We developed and validated a DNA methylation–based biomarker panel to distinguish pleural mesothelioma from other pleural conditions. Using the IMPRESS technology, we translated this panel into a clinically applicable assay. The resulting two classifier models demonstrated excellent performance, achieving high AUC values and strong diagnostic accuracy.

Magnification of Genes Coding for Ribosomal RNA in Saccharomyces cerevisiae [PDF]

open access: yes, 1977
When a strain of Saccharomyces cerevisiae monosomic for chromosome I and initially deficient for 25% of the genes coding for ribosomal RNA is repeatedly subcultured, the number of these genes increases to and remains stable at the number in the wild type.

Detection of circulating tumor DNA in colorectal cancer patients using a methylation‐specific droplet digital PCR multiplex

open access: yesMolecular Oncology, EarlyView.
We developed a cost‐effective methylation‐specific droplet digital PCR multiplex assay containing tissue‐conserved and tumor‐specific methylation markers. The assay can detect circulating tumor DNA with high accuracy in patients with localized and metastatic colorectal cancer.

Caracterização citogenética em Anadenanthera colubrina (Vell.) Brenan (Mimosoideae) e Guazuma ulmifolia Lam. (Sterculiaceae) Cytogenetic characterization in Anadenanthera colubrina (Vell.) Brenan (Mimosoideae) and Guazuma ulmifolia Lam. (Sterculiaceae)

open access: yesActa Botânica Brasílica, 2010
Análises cariotípicas são importantes ferramentas de auxílio aos estudos de relações taxonômicas dentro dos grupos vegetais. Espécies arbóreas nativas encontradas no cerrado brasileiro têm sido pouco analisadas do ponto de vista citogenético e ...

Identification of an interchromosomal compartment by polymerization of nuclear-targeted vimentin [PDF]

open access: yes, 1998
A number of structural and functional subnuclear compartments have been described, including regions exclusive of chromosomes previously hypothesized to form a reactive nuclear space.

Transcriptional network analysis of PTEN‐protein‐deficient prostate tumors reveals robust stromal reprogramming and signs of senescent paracrine communication

open access: yesMolecular Oncology, EarlyView.
Combining PTEN protein assessment and transcriptomic profiling of prostate tumors, we uncovered a network enriched in senescence and extracellular matrix (ECM) programs associated with PTEN loss and conserved in a mouse model. We show that PTEN‐deficient cells trigger paracrine remodeling of the surrounding stroma and this information could help ...
