Mutations in the polyglutamylase geneTTLL5, expressed in photoreceptor cells and spermatozoa, are associated with cone-rod degeneration and reduced male fertility

Hereditary retinal degenerations encompass a group of genetic diseases characterized by extreme clinical variability. Following next-generation sequencing and autozygome-based screening of patients presenting with a peculiar, recessive form of cone-dominat ...

Chemical Genetic Screen Identifies Natural Products that Modulate Centriole Number

Kai Johnsson, Pierre Gönczy, Zhou Fang, Michele Graciotti

Centrioles are microtubule-based organelles found in most eukaryotic cells and that are critical for the formation of cilia and flagella, as well as of centrosomes in animal cells. The number of centrioles must be strictly regulated in proliferating cells ...

Distinct mechanisms eliminate mother and daughter centrioles in meiosis of starfish oocytes

Pierre Gönczy

Centriole elimination is an essential process that occurs in female meiosis of metazoa to reset centriole number in the zygote at fertilization. How centrioles are eliminated remains poorly understood. Here we visualize the entire elimination process live ...

Male-killing symbiont damages host's dosage-compensated sex chromosome to induce embryonic apoptosis

Bruno Lemaitre, Toshiyuki Harumoto

Some symbiotic bacteria are capable of interfering with host reproduction in selfish ways. How such bacteria can manipulate host's sex-related mechanisms is of fundamental interest encompassing cell, developmental and evolutionary biology. Here, we uncover ...

On-chip microfluidic biocommunication assay for studying male-induced demise in C. elegans hermaphrodites

Thomas Lehnert, Martinus Gijs, Matteo Cornaglia, Li Dong

Like other animals, C. elegans nematodes have the ability to socially interact and to communicate through exchange and sensing of small soluble signaling compounds that help them cope with complex environmental conditions. For the time being, worm biocommu ...

Bile acid-FXR alpha pathways regulate male sexual maturation in mice

Kristina Schoonjans

The bile acid receptor Farnesol-X-Receptor alpha (FRX alpha) is a member of the nuclear receptor superfamily. FRX alpha is expressed in the interstitial compartment of the adult testes, which contain the Leydig cells. In adult, short term treatment (12 hou ...

Intra- and interspecific social challenges modulate the levels of an androgen precursor in a seasonally territorial tropical damselfish

Katarina Damjanovic

Studies on different vertebrate groups have provided evidence that androgen levels in males increase after competitive social interactions during the breeding season, as postulated by the Challenge Hypothesis. However, social modulation of androgen levels ...

Mechanisms of differential centriole inheritance in C. elegans

Lukas von Tobel

Centrosomes are the principal microtubule organizing center (MTOC) of animal cells and comprise a pair of centrioles surrounded by pericentriolar material (PCM). Centriole number must be carefully regulated to ensure bipolar spindle formation and thus fait ...

Bile Acids Alter Male Fertility Through G-Protein-Coupled Bile Acid Receptor 1 Signaling Pathways in Mice

Kristina Schoonjans

Bile acids (BAs) are signaling molecules that are involved in many physiological functions, such as glucose and energy metabolism. These effects are mediated through activation of the nuclear and membrane receptors, farnesoid X receptor (FXR-alpha) and TGR ...

Effects of ploidy and sex-locus genotype on gene expression patterns in the fire ant Solenopsis invicta

Laurent Keller, Oksana Riba Grognuz, Chitsanu Khurewathanakul

Males in many animal species differ greatly from females in morphology, physiology and behaviour. Ants, bees and wasps have a haplodiploid mechanism of sex determination whereby unfertilized eggs become males while fertilized eggs become females. However, ...

Defining the role of common variation in the genomic and biological architecture of adult human height

Paul Jack Mc Laren, Murielle Bochud, Jiancheng Yang, Zhaoming Wang

Using genome-wide data from 253,288 individuals, we identified 697 variants at genome-wide significance that together explained one-fifth of the heritability for adult height. By testing different numbers of variants in independent studies, we show that th ...
