Eiger/TNFα-mediated Dilp8 and ROS production coordinate intra-organ growth in Drosophila

Sanchez et al use the developing wing primordium of Drosophila to identify the molecular mechanisms and signaling molecules that mediate communication between adjacent cell populations upon a targeted reduction of growth rate. The authors reveal how different signals can regulate tissue growth and cell proliferation in an independent manner to coordinate the tissue size and cell number of different parts of an organ.

Identification of new components of the RipC-FtsEX cell separation pathway of Corynebacterineae

To enhance understanding of cell surface biogenesis in Corynebacterineae, Lim et al perform a global genetic analysis of gene function in the model system Corynebacterium glutamicum (Cglu) using transposon sequencing. In addition to defining the essential gene set in this organism, the authors also identify SteA and SteB as components of the cytokinetic ring.

An estimator of first coalescent time reveals selection on young variants and large heterogeneity in rare allele ages among human populations

Here, Platt et al develop a method to estimate the time when a copy of a gene most recently shared ancestry with other copies of that gene. The method also provides an estimate of the upper bound of when a mutation has arisen, and can be used to study the ages of alleles that are found in a population.

A conserved role of the insulin-like signaling pathway in diet-dependent uric acid pathologies in Drosophila melanogaster

Here, Lang et al identify a regulatory role for the insulin-like signaling cascade affecting uric acid (UA) metabolism using a Drosophila melanogaster model. The authors determine previously unrecognized potential drug targets to treat elevated UA levels and associated pathologies such as gout or UA kidney stones.

Tbx1 and Foxi3 genetically interact in the pharyngeal pouch endoderm in a mouse model for 22q11.2 deletion syndrome

The mechanisms required for segmentation of the pharyngeal apparatus to individual arches are not precisely delineated in mammalian species. Using mouse models, Hasten and Morrow find that two transcription factor genes, Tbx1 and Foxi3, genetically interact in the third pharyngeal pouch endoderm during thymus and parathyroid gland development.

Solving the missing heritability problem

In this Opinion Piece, Alexander Young discusses the 'missing heritability problem' - the gap between heritability estimates from genotype and twin data.
