Distinct contributions of MSL complex subunits to the transcriptional enhancement responsible for dosage compensation in Drosophila [PDF]

Nucleic Acids Research, 2012
The regulatory mechanism of dosage compensation is the paramount example of epigenetic regulation at the chromosomal level. In Drosophila, this mechanism, designed to compensate for the difference in the dosage of X-linked genes between the sexes, depends on the MSL complex that enhances the transcription of the single dose of these genes in males.

Two‐Photon Grayscale Lithography (2GL) of High Mechanical and Optical Quality 3D Silica Glass Microstructures

Advanced Functional Materials, EarlyView.
Two‐photon grayscale lithography (2GL) enables high‐speed and precise 3D printing of thermolyzed silica glass microstructures with optical‐grade surface quality, high quality factors, and mechanical strength utilizing a custom‐made pre‐glass resist based on polyhedral oligomeric silsesquioxane (POSS) modified with a high‐sensitivity Norrish type II ...

The Drosophila Dosage Compensation Complex Binds to Polytene Chromosomes Independently of Developmental Changes in Transcription [PDF]

Genetics, 2006
Abstract In Drosophila, the dosage compensation complex (DCC) mediates upregulation of transcription from the single male X chromosome. Despite coating the polytene male X, the DCC pattern looks discontinuous and probably reflects DCC dynamic associations with genes active at a given moment of development in a salivary gland.

“Jump Start and Gain” Model for Dosage Compensation in Drosophila Based on Direct Sequencing of Nascent Transcripts

Cell Reports, 2013
Dosage compensation in Drosophila is mediated by the MSL complex, which increases male X-linked gene expression approximately 2-fold. The MSL complex preferentially binds the bodies of active genes on the male X, depositing H4K16ac with a 3′ bias.

Bio‐Inspired Artificial Ionic Mechanoreceptor

Advanced Functional Materials, EarlyView.
A skin‐inspired artificial mechanoreceptor based on ionic interactions is presented for biomimetic tactile sensing. Pressure‐driven ionic redistribution within microfluidic channels generates a self‐powered electrical signal without external bias. The generated waveform exhibits mechanoreceptor‐like temporal features, including overshoot and undershoot,

A condensin-like dosage compensation complex acts at a distance to control expression throughout the genome [PDF]

Genes & Development, 2009
In many species, a dosage compensation complex (DCC) is targeted to X chromosomes of one sex to equalize levels of X-gene products between males (1X) and females (2X). Here we identify cis-acting regulatory elements that target the Caenorhabditis elegans X chromosome for repression by the DCC.

An Integrated Oxygen‐Supplying Device and Predictive Multiphysics Model for Extended Ambient Transport of Insulin‐Producing Cells

Advanced Functional Materials, EarlyView.
Cell therapies typically rely on cold‐chain logistics and cryopreservation, limiting access and compromising cell quality. Here, a dual‐chamber device separates an oxygen‐supplying chamber from a hyaluronic acid cargo chamber, sustaining oxygen delivery for over 70 h and enabling ambient‐temperature shipment.

Ubiquitylation of the acetyltransferase MOF in Drosophila melanogaster.

PLoS ONE, 2017
The nuclear acetyltransferase MOF (KAT8 in mammals) is a subunit of at least two multi-component complexes involved in transcription regulation. In the context of complexes of the 'Non-Specific-Lethal' (NSL) type it controls transcription initiation of ...
