Iron metabolism in the social amoeba Dictyostelium discoideum: A role for ferric chelate reductases

European Journal of Cell Biology, 2022
Iron is the most abundant transition metal in all living organisms and is essential for several cellular activities, including respiration, oxygen transport, energy production and regulation of gene expression.

Comprehensive Analysis Reveals Dynamic and Evolutionary Plasticity of Rab GTPases and Membrane Traffic in Tetrahymena thermophila [PDF]

, 2010
Cellular sophistication is not exclusive to multicellular organisms, and unicellular eukaryotes can resemble differentiated animal cells in their complex network of membrane-bound structures. These comparisons can be illuminated by genome-wide surveys of

Hepato‐Renal Damage of Hyaluronic Acid on the African Catfish (Clarias gariepinus)

Aquaculture Research, Volume 2025, Issue 1, 2025.
Hyaluronic acid (HA) is a versatile polysaccharide with a broad range of biological, pharmacological, and therapeutic applications due to its anti‐inflammatory properties, low immunogenicity, natural breakdown, compatibility with live tissue, and capacity to promote cell growth and specialization.

Self-propulsion of an active polar drop [PDF]

, 2019
We investigate the self-propulsive motion of a drop containing an active polar field. The drop demonstrates spontaneous symmetry breaking from a uniform orientational order into a splay or bend instability depending on the types of active stress, namely, contractile or extensile, respectively.

Overexpression of enhanced yellow fluorescent protein fused with Channelrhodopsin‐2 causes contractile dysfunction in skeletal muscle

The FASEB Journal, Volume 38, Issue 22, 30 November 2024.
Optogenetic tools like Channelrhodpsin‐2 (ChR2) are useful for inducing skeletal muscle contraction using blue light. However, the prevalence of fluorescent proteins like EYFP may cause functional issues. Here, Lamia et al. showed that the contractile properties of ChR2‐EYFP skeletal muscle had aggregated EYFP in sarcolemma, decreased contractile force

Trypanosomatid Aquaporins: Roles in Physiology and Drug Response [PDF]

, 2013
In the class Kinetoplastida, we find an order of parasitic protozoans classified as Trypanosomatids. Three major pathogens form part of this order, Trypanosoma cruzi, Trypanosoma brucei, and Leishmania, which are responsible for disease and fatalities in

Morphologic and Molecular Description of \u3cem\u3eMetopus fuscus\u3c/em\u3e Kahl from North America and New rDNA Sequences from Seven Metopids (Armophorea, Metopidae) [PDF]

, 2014
Most species in the large ciliate genus Metopus Claparède & Lachmann, 1858 lack detailed descriptions based on modern morphologic and molecular methods. This lack of data for the vast majority of species hampers application of a morphospecies approach to

Studies on Ciliates from Mollusks of Iowa [PDF]

, 1958
The ciliates which live a commensal life on the gills and in the mantle cavities of mollusks include several species of peritrichs, but most of them belong to a suborder of holotrichs called Thigmotricha (Chatton and Lwoff, 1922).

Systemic infection of freshwater crayfish Cherax quadricarinatus by hymenostome ciliates of the Tetrahymena pyriformis complex [PDF]

, 1996
A survey of cultured freshwater crayfish Cherax quadricarinatus in north Queensland revealed systemic infections by hymenostome ciliates in moribund crayfish from one location. The ciliates were identified following protargol impregnation as belonging to

A Rab4-like GTPase in Dictyostelium discoideum colocalizes with V-H(+)-ATPases in reticular membranes of the contractile vacuole complex and in lysosomes [PDF]

, 1994
In the course of screening a cDNA library for ras-related Dictyostelium discoideum genes, we cloned a 0.7 kb cDNA (rabD) encoding a putative protein that was 70% identical at the amino acid level to human Rab4.
