Novel and unscrutinized immune entities of the zebrafish gut

FEBS Letters, EarlyView.
Understudied cells of the zebrafish immune system include bona fide immune cells and epithelial (‐derived) cells with immune functions. Research focusing on zebrafish cells which demonstrate similarities to mammalian immune cell counterparts may help us understand the pathologies in which they are implicated. Currently available and advanced tools make

Mitochondrial Handling of Excess Ca\u3csup\u3e2+\u3c/sup\u3e is Substrate-dependent with Implications for Reactive Oxygen Species Generation [PDF]

, 2013
The mitochondrial electron transport chain is the major source of reactive oxygen species (ROS) during cardiac ischemia. Several mechanisms modulate ROS production; one is mitochondrial Ca2+ uptake.

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

FEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

Mitochondrial function in Antarctic nototheniids with ND6 translocation.

PLoS ONE, 2012
Fish of the suborder Notothenioidei have successfully radiated into the Southern Ocean and today comprise the dominant fish sub-order in Antarctic waters in terms of biomass and species abundance. During evolution in the cold and stable Antarctic climate,

Mitochondrial complex II of plants: subunit composition, assembly, and function in respiration and signaling.

The Plant Journal, 2019
Complex II [succinate dehydrogenase (succinate-ubiquinone oxidoreductase); EC 1.3.5.1; SDH] is the only enzyme shared by both the electron transport chain and the tricarboxylic acid (TCA) cycle in mitochondria.

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Reprofiling a classical anthelmintic, pyrvinium pamoate, as an anti-cancer drug targeting mitochondrial respiration.

Frontiers in Oncology, 2012
Pyrvinium pamoate (PP) is an FDA-approved classical anthelmintic, but is now attracting particular attention as an anti-cancer drug after recent findings of its potent cytotoxicity against various cancer cell lines only during glucose starvation, as well

The effect of nicosulfuron and bentazon on photosynthetic performance of common cocklebur (Xanthium strumarium L.)

Environmental and Sustainability Indicators, 2020
In order to evaluate the effects of bentazon and nicosulfuron on the photosynthetic apparatus of X. strumarium in greenhouse condition, chlorophyll a fluorescence (ChlF) method was studied at 1, 2, 3, and 4 days after herbicide treatment (DAHT). Bentazon

Metformin promotes lifespan through mitohormesis via the peroxiredoxin PRDX-2 [PDF]

, 2014
The antiglycemic drug metformin, widely prescribed as first-line treatment of type II diabetes mellitus, has lifespan-extending properties. Precisely how this is achieved remains unclear.
