TL;DR: Among patients with stage II breast cancer, lack of Smad2P expression in the tumor was strongly associated with shorter overall survival, and analysis of a small cohort of hereditary breast cancers failed to reveal any association between BRCA1 or BRCa2 genotype and alterations in Smad signaling.
Abstract: Based largely on studies of cell lines in vitro and of transgenic mouse models, disruptions of transforming growth factor (TGF) beta signaling are thought to contribute to the development and progression of human breast cancer. However, whether and how TGF-beta signaling becomes disrupted during human breast cancer development in vivo remains largely unknown. To address this question, we have compared the patterns of expression and activation of the postreceptor components of the TGF-beta signaling pathway, the so-called Smads, in human breast cancer cell lines with those in breast carcinoma specimens. None of the breast carcinoma cell lines were growth arrested by TGF-beta in vitro. Each of the tumor cell lines expressed normal levels of Smad2 and -3. Moreover, TGF-beta treatment induced phosphorylation of Smad2 (Smad2P) in each of these lines, except those that lacked TGF-beta type II receptors. Moreover, only one of the cell lines failed to express Smad4. Among 456 cases of human breast carcinoma assembled in tissue microarrays, the majority (92%) expressed Smad2, Smad2P, as well as Smad4, indicating their ability to proliferate within a microenvironment that contains bioactive TGF-beta. Thirty cases (6.6%) failed to express Smad2P, suggesting the loss of TGF-beta receptor signaling. Nine cases (2%) failed to express Smad4, and 3 of these also failed to express Smad2P. Thus, the phenotypes of breast tumors in vivo paralleled that of human breast cancer cell lines in terms of Smad2P and Smad4 expression. Loss of Smad signaling was not associated with any particular histological subtype, histological or nuclear grade, estrogen- or progesterone receptor expression, or HER2/neu expression. Loss of Smad4 was inversely correlated with the presence of axillary lymph node metastases. Most importantly, among patients with stage II breast cancer, lack of Smad2P expression in the tumor was strongly associated with shorter overall survival. Finally, analysis of a small cohort of hereditary breast cancers failed to reveal any association between BRCA1 or BRCA2 genotype and alterations in Smad signaling.

TL;DR: It is demonstrated that microRNAs are aberrantly expressed in vascular smooth muscle cells (VSMCs) after treatment with hydrogen peroxide (H2O2) and the results suggest that miRNAs in VSMCs are sensitive to H 2O2 stimulation.

TL;DR: Methylation marks on the lysine residues of histone proteins are thought to contribute to epigenetic phenomena in part because of their apparent irreversibility, but will this view change with the recent discovery of Histone lysines demethylases that reversibly remove methyl marks?

TL;DR: It is found that vegetarians develop B12 depletion or deficiency regardless of demographic characteristics, place of residency, age, or type of vegetarian diet, and should take preventive measures to ensure adequate intake of this vitamin, including regular consumption of supplements containing B12.
Abstract: Vegetarians are at risk for vitamin B12 (B12) deficiency due to suboptimal intake. The goal of the present literature review was to assess the rate of B12 depletion and deficiency among vegetarians and vegans. Using a PubMed search to identify relevant publications, 18 articles were found that reported B12 deficiency rates from studies that identified deficiency by measuring methylmalonic acid, holo-transcobalamin II, or both. The deficiency rates reported for specific populations were as follows: 62% among pregnant women, between 25% and almost 86% among children, 21–41% among adolescents, and 11–90% among the elderly. Higher rates of deficiency were reported among vegans compared with vegetarians and among individuals who had adhered to a vegetarian diet since birth compared with those who had adopted such a diet later in life. The main finding of this review is that vegetarians develop B12 depletion or deficiency regardless of demographic characteristics, place of residency, age, or type of vegetarian diet. Vegetarians should thus take preventive measures to ensure adequate intake of this vitamin, including regular consumption of supplements containing B12.

TL;DR: Suggestions for developing and implementing curricula for cultural competency, teaching content, specific integrative learning strategies, methods for evaluating nursing students' cultural competence and recommendations for effective implementation of the integrated curriculum are presented.
Abstract: This article presents the work of the American Association of Colleges of Nursing Advisory Committee in developing an integrated curriculum for cultural competence in baccalaureate nursing education. Five competencies for Cultural Competency in Baccalaureate Nursing Education were developed with supporting rationale. Suggestions for developing and implementing curricula for cultural competency, teaching content, specific integrative learning strategies, methods for evaluating nursing students' cultural competence and recommendations for effective implementation of the integrated curriculum are presented.
