Article Abstract

Astrocytes are predominant glial cells that tile the central nervous system and participate in well-established functional and morphological interactions with neurons, blood vessels, and other glia. These ubiquitous cells display rich intracellular Ca signaling, which has now been studied for over 30 years. In this review, we provide a summary and perspective of recent progress concerning the study of astrocyte intracellular Ca signaling as well as discussion of its potential functions. Progress has occurred in the areas of imaging, silencing, activating, and analyzing astrocyte Ca signals. These insights have collectively permitted exploration of the relationships of astrocyte Ca signals to neural circuit function and behavior in a variety of species. We summarize these aspects along with a framework for mechanistically interpreting behavioral studies to identify directly causal effects. We finish by providing a perspective on new avenues of research concerning astrocyte Ca signaling.

Glioma is a highly aggressive and invasive brain tumor with limited treatment options, highlighting the need for novel therapeutic approaches. Kinesin superfamily proteins (KIFs) are a diverse group of motor proteins that play essential roles in cellular processes such as mitosis, intracellular transport, and signal transduction, all of which are crucial for tumorigenesis. This review focuses on the multifaceted role of KIFs in glioma, examining their clinical relevance, contribution to tumor progression, and potential as therapeutic targets.

Manganese (Mn) is a neurotoxin that has been etiologically linked to the development of neurodegenerative diseases in the case of overexposure. It is widely accepted that overexposure to Mn leads to manganism, which has clinical symptoms similar to Parkinson's disease (PD), and is referred to as parkinsonism. Astrocytes have been reported to scavenge and degrade extracellular α-synuclein (α-Syn) in the brain.

Pancreatic ductal adenocarcinoma (PDAC) poses a significant challenge in oncology due to its dismal prognosis and limited therapeutic options. In this study, we investigated the role of miR-301a in facilitating crosstalk between the Hedgehog (Hh) and HIPPO/YAP signaling pathways during the progression of PDAC. Our findings revealed that miR-301a served as a central regulatory node, targeting Gli1 within the Hh pathway and STK4 within the HIPPO/YAP pathway.

Pigeons and certain other avian species produce a milk-like secretion in their crop sacs to nourish offspring, yet the detailed processes involved are not fully elucidated. This study investigated the crop sacs of 225-day-old unpaired non-lactating male pigeons (MN) and males initiating lactation on the first day after incubation (ML). Using RNA sequencing, ribosome profiling, and single-cell transcriptome sequencing (scRNA-seq), we identified a significant up-regulation of genes associated with ribosome assembly and protein synthesis in ML compared to MN.

Golgi protein 73: the driver of inflammation in the immune and tumor microenvironment.

Golgi Protein 73 (GP73) is a Golgi-resident protein that is highly expressed in primary tumor tissues. Initially identified as an oncoprotein, GP73 has been shown to promote tumor development, particularly by mediating the transport of proteins related to epithelial-mesenchymal transition (EMT), thus facilitating tumor cell EMT. Though our previous review has summarized the functional roles of GP73 in intracellular signal transduction and its various mechanisms in promoting EMT, recent studies have revealed that GP73 plays a crucial role in regulating the tumor and immune microenvironment.
