Summary: Intracellular trafficking plays a critical role in the functioning of highly polarized cells, such as neurons. Transport of mRNAs, proteins, and other molecules to synaptic terminals maintains contact between neurons and ensures the transmission of nerve impulses. Cytoplasmic polyadenylation element binding (CPEB) proteins play an essential role in long-term memory (LTM) formation by regulating local translation in synapses.

Summary: Pre-mRNA splicing is a critical mechanism in gene expression in eukaryotes, and splicing inhibition can impact various cellular functions. This study reveals that the potent splicing inhibitor spliceostatin A (SSA) causes stabilization of the p27 protein by increasing the stability of CDKN1B mRNA. The 3' untranslated region of CDKN1B mRNA is involved in this stabilization process.

Summary: In this study, sheep were used as an animal model to investigate the regulatory mechanisms of cis-elements in the cytoplasmic polyadenylation and translation of maternal mRNAs in domestic animal oocytes. The positioning and number of polyadenylation signal (PAS) and cytoplasmic polyadenylation element (CPE) in the 3'-UTR were found to affect the efficiency of translational control.

Summary: Alternative cleavage and polyadenylation (APA) is prevalent in more than 70% of human and mouse genes, with distal poly(A) site selection influencing thousands of genes in the nervous system. Using mouse embryonic stem cell-derived neurons as a model system, researchers demonstrated widespread 3' UTR lengthening that closely resembles APA patterns in mouse cortex. CRISPR/Cas9 editing allows for efficient elimination of long 3' UTR isoform expression, with Oxford Nanopore Technologies platform providing a cost-effective strategy to confirm specific loss of targeted isoforms.

Summary: Chronic inflammation is a major cause of disease. This study reveals the counterbalancing actions of RNA-binding proteins CPEB4 and TTP in inflammation resolution. CPEB4 stabilizes anti-inflammatory transcripts, while TTP directs mRNA deadenylation. The activities of CPEB4 and TTP are regulated through MAPK signaling. Maintaining the balance between these two opposing mechanisms is crucial for efficient inflammation resolution.

Summary: Resistance to targeted therapy is a challenge in breast, lung, and colorectal cancers, leading to a large number of deaths annually. We found that ERBB2+ cancer cells have mRNA-stabilizing sequences on their 3'UTR. By manipulating these sequences, we successfully degraded ERBB2 transcripts and reduced protein levels in various cancer cell types, providing a new approach to control oncogenic signals where current therapies fail.

Summary: Glutamine synthetase (GS) is a crucial enzyme for nitrogen assimilation under nitrogen limiting conditions. This study reveals that an sRNA GlnZ and a transcriptional regulator Nac both play roles in repressing the expression of the sucA component of 2-oxoglutarate dehydrogenase, thereby controlling the metabolic flow in response to nitrogen availability.

Summary: The Yes-associated protein (YAP) is a transcriptional co-activator crucial for organ development and tumorigenesis, inhibited by the Hippo signaling pathway. In human cancer cells, alternative splicing of YAP 3' UTR generates a shorter mRNA with potential impact on YAP expression. PKC inhibitor affects the ratio of different YAP mRNA forms, implicating PKC in the regulation of YAP expression through alternative splicing.

Summary: The study revealed the presence of MSPs in the enoplean nematode Enoplus brevis, showing filamentous structures in sperm similar to chromadorean nematodes. E. brevis MSPs exhibit lower homology to known proteins in rhabditids, indicating more distant evolutionary relationships between Enoplea and Chromadorea. This data suggests a need to reevaluate current views of MSP evolution within Nematoda.

Summary: The Y chromosome is a sex chromosome found in male animals and undergoes dynamic evolutionary changes. It is characterized by unique chromatin landscapes and is enriched in tandem repeats and transposons. Despite structural divergence, Y-linked genes are mainly associated with spermatogenesis and male-specific selection shapes the evolution of Y chromosomes.

These symbionts are important enough for the ant hosts to have evolved functional defense mechanisms.

Summary: This study aimed to evaluate the reliability of RT-qPCR in analyzing the levels of maternal transcripts in the sea urchin egg cortex. By selecting potential reference genes and ranking them, the study found that the ranking of transcripts differed between total RNA and mRNA samples, but Ubb was the most suitable reference gene in both cases. By validating the gene of interest Daglb-2, the study observed an increased level of Daglb-2 in the egg cortex, suggesting that the proposed RNA isolation method with subsequent quantitative RT-qPCR analysis can be used to determine the cortical association of transcripts in sea urchin eggs.

Summary: Nanoparticles can be transported via the nose-to-brain (N2B) route, and this study focused on the dynamics and regulation of N2B transport using metal oxide/hydroxide NPs as MRI contrasts. The research revealed the movement and transport mechanism of Mn3O4-NPs within neurons and their trans-synaptic transmission, which are dependent on neuronal activity and synaptic stability. These findings have important implications for diagnostics, functional neuroimaging, and controlling N2B drug delivery.

Summary: Nanoparticles can be transported from the nose to the brain and tracked using MRI. Mn3O4-NPs were found to be readily taken up by olfactory neurons and transported through axons, synapses, and across the olfactory tract. The transport of NPs was dependent on neuronal activity, microtubule integrity, calcium channels, and receptors. Olfactory stimuli could modulate and reroute the N2B transport of Mn3O4-NPs, and this transmission was impaired in aging and Parkinson's disease.
