Polytene chromosomes as indicators of phylogeny in several species groups of Drosophila. [PDF]

open access: yes, 2001
BackgroundPolytene chromosome banding patterns have long been used by Drosophila evolutionists to infer degree of relatedness among taxa. Recently, nucleotide sequences have preempted this traditional method.

RNA-DNA strand exchange by the Drosophila Polycomb complex PRC2. [PDF]

open access: yes, 2020
Polycomb Group (PcG) proteins form memory of transient transcriptional repression that is necessary for development. In Drosophila, DNA elements termed Polycomb Response Elements (PREs) recruit PcG proteins.

Drosophila Myc

open access: yesAdvances in cancer research, 2009
Myc genes play a major role in human cancer, and they are important regulators of growth and proliferation during normal development. Despite intense study over the last three decades, many aspects of Myc function remain poorly understood. The identification of a single Myc homolog in the model organism Drosophila melanogaster more than 10 years ago ...

Ethnomedicinal Uses, Phytochemistry, Pharmacological Activities, and Toxicology of the Subfamily Gomphrenoideae (Amaranthaceae): A Comprehensive Review

open access: yesChemistry &Biodiversity, EarlyView.
ABSTRACT The subfamily Gomphrenoideae is composed of about 480 accepted species, many of which have been historically used as medicinal plants, reason why they have been studied in terms of chemical profile, biological activity, and safety. This review consolidates the advances in research on this subfamily over the past 47 years, emphasizing its ...

Methods for Controlling Small GTPase Activity

open access: yesChemBioChem, Accepted Article.
Small GTPases comprise a diverse class of signaling proteins in mammalian cells and regulate a variety of cellular processes such as cell growth, cell movement, vesicle formation, and nuclear transport. Due to their involvement in critical cellular pathways, changes in the activation state of small GTPases due to genetic mutations or alterations in ...

Microtubules Stabilization by Mutant Spastin Affects ER Morphology and Ca2+ Handling

open access: yesFrontiers in Physiology, 2019
The endoplasmic reticulum (ER) extends as a network of interconnected tubules and sheet-like structures in eukaryotic cells. ER tubules dynamically change their morphology and position within the cells in response to physiological stimuli and these ...

Myosin VI Is Associated With the Endoplasmic Reticulum in Regions of Sertoli Cells Containing Tubulobulbar Complexes

open access: yesCytoskeleton, EarlyView.
ABSTRACT Myosin VI has been reported by others to localize in association with various regions of apical tubulobulbar complexes (TBCs) at sites of attachment between Sertoli cells and late spermatids in the mouse. Tubulobulbar complexes internalize “intact” intercellular junctions during sperm release and during spermatocyte translocation through the ...

Single‐Molecule Tracking and Super‐Resolution Microscopy Unveil Actin‐Driven Membrane Nanotopography Shaping Stable Integrin Adhesions in Developing Tissue

open access: yesCytoskeleton, EarlyView.
ABSTRACT Single molecule tracking and super‐resolution microscopy of integrin adhesion proteins and actin in developing Drosophila muscle attachment sites reveals that nanotopography triggered by Arp2/3‐dependent actin protrusions promotes stable adhesion formation.
