Mapping gene expression as a quantitative trait using whole genome-sequencing and transcriptome analysis allows to discover the functional consequences of genetic variation . We developed a novel method and ultra-fast software Findr for higly accurate causal inference between gene expression traits using cis-regulatory... | Understanding how genetic variation between individuals determines variation in observable traits or disease risk is one of the core aims of genetics . It is known that genetic variation often affects gene regulatory DNA elements and directly causes variation in expression of nearby genes . This effect in turn cascades... | [

In Drosophila melanogaster , the male-specific lethal ( MSL ) complex plays a key role in dosage compensation by stimulating expression of male X-chromosome genes . It consists of MSL proteins and two long noncoding RNAs , roX1 and roX2 , that are required for spreading of the complex on the chromosome and are redundan... | In humans and fruit flies , females and males have different sets of sex chromosomes . This causes gene dosage differences that must be compensated for by adjusting the expression of most genes located on the X-chromosome .

Gene expression actualizes the organismal phenotypes encoded within the genome in an environment-dependent manner . Among all encoded phenotypes , cell population growth rate ( fitness ) is perhaps the most important , since it determines how well-adapted a genotype is in various environments . Traditional biological m... | It is common belief that the properties of cells depend on their environment and on the genes they carry .

Synaptic vesicle fusion is mediated by SNARE proteins forming in between synaptic vesicle ( v-SNARE ) and plasma membrane ( t-SNARE ) , one of which is Syntaxin-1A .

By using STED super-resolution light micro... | For the communication between two nerve cells , a synaptic vesicle containing neurotransmitters has to fuse with the neuronal membrane at a specific fusion site , releasing its signaling molecules .
