Luteolin regulates the distribution and function of organelles by controlling SIRT1 activity during postovulatory oocyte aging

open access: yesFrontiers in Nutrition, 2023
The quality of oocytes determines their development competence, which will be rapidly lost if the oocytes are not fertilized at the proper time after ovulation.

Protein import into the endosymbiotic organelles of apicomplexan parasites [PDF]

open access: yes, 2018
The organelles of endosymbiotic origin, plastids, and mitochondria, evolved through the serial acquisition of endosymbionts by a host cell. These events were accompanied by gene transfer from the symbionts to the host, resulting in most of the organellar

AIEgen-Peptide Bioprobes for the Imaging of Organelles

open access: yesBiosensors, 2022
Organelles are important subsystems of cells. The damage and inactivation of organelles are closely related to the occurrence of diseases. Organelles’ functional activity can be observed by fluorescence molecular tools.

Toxoplasma gondii Syntaxin 6 is required for vesicular transport between endosomal-like compartments and the Golgi Complex [PDF]

open access: yes, 2013
Apicomplexans are obligate intracellular parasites that invade the host cell in an active process that relies on unique secretory organelles (micronemes, rhoptries and dense granules) localized at the apical tip of these highly polarized eukaryotes ...

Loss of the Conserved Alveolate Kinase MAPK2 Decouples Toxoplasma Cell Growth from Cell Division

open access: yesmBio, 2020
Mitogen-activated protein kinases (MAPKs) are a conserved family of protein kinases that regulate signal transduction, proliferation, and development throughout eukaryotes. The apicomplexan parasite Toxoplasma gondii expresses three MAPKs.

Membrane-Bound Meet Membraneless in Health and Disease

open access: yesCells, 2019
Membraneless organelles (MLOs) are defined as cellular structures that are not sealed by a lipidic membrane and are shown to form by phase separation. They exist in both the nucleus and the cytoplasm that is also heavily populated by numerous membrane ...

Evolutionary cell biology: Functional insight from “Endless forms most beautiful” [PDF]

open access: yes, 2015
In animal and fungal model organisms, the complexities of cell biology have been analyzed in exquisite detail and much is known about how these organisms function at the cellular level.

Kinesin Light Chains Are Essential for Axonal Transport in Drosophila [PDF]

open access: yes, 1998
Kinesin is a heterotetramer composed of two 115-kD heavy chains and two 58-kD light chains. The microtubule motor activity of kinesin is performed by the heavy chains, but the functions of the light chains are poorly understood.

Coming together to define membrane contact sites. [PDF]

open access: yes, 2019
Close proximities between organelles have been described for decades. However, only recently a specific field dealing with organelle communication at membrane contact sites has gained wide acceptance, attracting scientists from multiple areas of cell ...
