Unique centromere type discovered in the European dodder
Commonly, the presence of histone variant CENH3 epigenetically determines the positioning of centromeres. In monocentric chromosomes, CENH3 occurs in a single region, whilst in holocentrics, CENH3 is distributed along the entire chromosome. Scientists have discovered a new type of centromere in the plant Cuscuta europae. Centromere activity is distributed in holocentric fashion, despite CENH3 only occurring on 1 to 3 distinct regions on the chromosome. The findings were published in Frontiers in Plant Sciences.

Temple scientists ID new targets to treat fibrosis -- a feature of many chronic diseases
When it comes to repairing injured tissue, specialized cells in the body known as fibroblasts are called into action. Fibroblasts give rise to healing cells called myofibroblasts, which generally is good in the short term -- but bad when myofibroblast activation gets out of hand. Now, Lewis Katz School of Medicine at Temple University researchers show how fibroblast activation and myofibroblast formation occurs, providing clues for how to target fibrosis -- which impacts several chronic diseases. (2019-10-04)

Biologists pioneer first method to decode gene expression
Biologists have developed the first system for determining gene expression based on machine learning. Considered a type of genetic Rosetta Stone for biologists, the new method leverages algorithms trained on a set of known plant genes to determine a species-wide set of transcribed genes, or 'expressome,' then creates an atlas of expressible genes. The method carries implications across biology, from drug discovery to plant breeding to evolution. (2019-08-12)

Gene-chip studies provide new leads in treating lung disease of premature newborns
Some 20 to 40 percent of extremely premature infants suffer abnormal lung development leading to bronchopulmonary dysplasia, a chronic lung disease that can cause long-term breathing problems. Little is known about how to predict whether a premature infant will develop BPD in the weeks after birth, much less how to prevent or treat it. Now, gene-chip studies of these tiny babies' umbilical cords provide unexpected, much-needed leads into predicting and treating this debilitating condition. (2007-10-03)

Intraepithelial neoplasia may be a leading risk factor for prostate and ovarian cancers
Intraepithelial neoplasia is a precancerous, noninvasive lesion that may signal the onset of tumor development in both the prostate and ovary, according to research presented today at the American Association for Cancer Research (AACR) Second Annual International Conference on Frontiers in Cancer Prevention Research. Both prostate and ovarian cancers are common and deadly, and novel preventive or early detection techniques are extremely important. (2003-10-27)

Tight DNA packaging protects against 'jumping genes,' potential cellular destruction
Scientists discovered that the major developmental function of heterochromatin -- a form of tight DNA packaging found in chromosomes -- is likely the suppression of virus-like DNA elements known as transposons or 'jumping genes,' which can otherwise copy and paste themselves throughout the genome, potentially destroying important genes, and causing cancers and other diseases.
