Remodeling of ER Membrane Contact Sites During Cell Division.
Contact (Thousand Oaks)
January 2025
Calcium Signaling Group, Research Department, Weill Cornell Medicine Qatar, Doha, Qatar.
Membrane contact sites (MCS) provide specialized conduits for inter-organelle communications to maintain cellular homeostasis. Most organelles are interconnected, which supports their coordination and function. M-phase (mitosis or meiosis) is associated with dramatic cellular remodeling to support cell division, including the equal distribution of organelles to the two daughter cells.

Micro(nano)plastics (MNPs), widely distributed in the environment, can be ingested and accumulated by various organisms. Recently, the transgenerational transport of MNPs from parental organisms to their offspring has attracted increasing attention. In this review, we summarize the patterns, specific pathways, and related mechanisms of intergenerational transfer of MNPs in plants, non-mammals (zooplankton and fish) and mammals.

Cell fate decisions during cortical development sculpt the identity of long-range connections that subserve complex behaviors. These decisions are largely dictated by mutually exclusive transcription factors, including CTIP2/Bcl11b for subcerebral projection neurons and BRN1/Pou3f3 for intra-telencephalic projection neurons. We have recently reported that the balance of cortical CTIP2-expressing neurons is altered in a mouse model of DDX3X syndrome, a female-biased neurodevelopmental disorder associated with intellectual disability, autism spectrum disorder, and significant motor challenges.

Concern over nanoplastic contamination of wetland ecosystems has been increasing. However, little is known about the effect of photoaging on the distribution and biological response of the nanoplastics. Here, palladium-labeled polystyrene nanoplastics (PS-Pd NPs) at 0.

University of Rzeszow, Institute of Food Technology and Nutrition, Zelwerowicza 4, 35-601, Rzeszow, Poland.
The hunting of waterfowl may contribute significantly to environmental contamination through the leaching of highly toxic elements (As, Pb, Sb) from spent gunshot deposited on hunting grounds. It is therefore clearly necessary to develop a biogeochemical protocol that might decipher the fate of spent gunshot in the environment. In that context, we present a study that follows the laboratory simulation approach and discusses the methodical pros and cons of the protocol.
