WDNE: an integrative graphical model for inferring differential networks from multi-platform gene expression data with missing values.

Brief Bioinform 2021 May 11. Epub 2021 May 11.

Department of Electrical Engineering, City University of Hong Kong, Hong Kong, 999077, China.

The mechanisms controlling biological process, such as the development of disease or cell differentiation, can be investigated by examining changes in the networks of gene dependencies between states in the process. High-throughput experimental methods, like microarray and RNA sequencing, have been widely used to gather gene expression data, which paves the way to infer gene dependencies based on computational methods. However, most differential network analysis methods are designed to deal with fully observed data, but missing values, such as the dropout events in single-cell RNA-sequencing data, are frequent.

A critical review of the mechanisms involved in the occurrence of growth-related abnormalities affecting broiler chicken breast muscles.

Poult Sci 2021 Apr 20;100(6):101180. Epub 2021 Apr 20.

Department of Agricultural and Food Sciences, Alma Mater Studiorum - University of Bologna, Italy.

In the past decade, the poultry industry has faced the occurrence of growth-related muscular abnormalities that mainly affect, with a high incidence rate, the Pectoralis major of the fast-growing genotypes selected for their production performances (high growth rate and breast yield). These myopathies are termed as White Striping, Wooden Breast, and Spaghetti Meat and exhibit distinctive phenotypes. A spatiotemporal distribution has been demonstrated for these disorders as in the early stage they primarily affect the superficial area in the cranial portion of the muscle and, as the birds grow older, involve the entire tissue.

Part-time cancers and role of melatonin in determining their metabolic phenotype.

Life Sci 2021 May 8:119597. Epub 2021 May 8.

Departamento de Biologia Estrutural e Funcional, Instituto de Biociencias, Botucatu, Sao Poalo 18618-689, Brazil.

This brief review describes the association of the endogenous pineal melatonin rhythm with the metabolic flux of solid tumors, particularly breast cancer. It also summarizes new information on the potential mechanisms by which endogenously-produced or exogenously-administered melatonin impacts the metabolic phenotype of cancer cells. The evidence indicates that solid tumors may redirect their metabolic phenotype from the pathological Warburg-type metabolism during the day to the healthier mitochondrial oxidative phosphorylation on a nightly basis.
