ALKBH1: emerging biomarker and therapeutic target for cancer treatment.

As neoplastic cells proliferate, disseminate, and infiltrate, they undergo substantial alterations in their epigenetic configuration. Among the pivotal enzymes implicated in this phenomenon is the AlkB family of demethylases, notably AlkB homolog 1 (ALKBH1), which demonstrates conspicuous upregulation across various malignancies. The heightened expression of ALKBH1 renders it a compelling candidate for the development of multifaceted anticancer modalities.

LncRNA Recognition-Associated CpG Island Detection and Methylation Analysis.

CpG islands (CGIs) are rare, interspersed DNA sequences, which possess a significant deviation from background genomic distribution by exhibiting patterns of GC-rich and CpG-rich sequence, the density of which provides a good classification feature for long noncoding RNA (lncRNA) promoters. By reviewing previous CpG-related studies, we consider that the transcription regulation of about half of the human genes, mostly housekeeping (HK) genes, involves CGIs, their methylation states, CpG spacing, and other chromosomal parameters. However, the precise CGI definition and positioning of CGIs within gene structures, as well as specific CGI-associated regulatory mechanisms, all remain to be elucidated at individual gene and gene family levels, together with consideration of species and lineage specificity.

Suppressing GDF15 enhances the chemotherapeutic effect of 5 FU on MSI-H CRC by regulating the ferroptosis pathway SLC7A11/GSH/GPX4.

Growth differentiation factor 15 (GDF15) is a member of the transforming growth factor beta (TGF-β) superfamily and is related to metabolism, injury, and aging. GDF15 has both tumor-promoting and tumor-suppressing effects. However, its role in colorectal cancer (CRC) with high microsatellite instability (MSI-H) must be further clarified.

Safe Transfer-Reinforcement-Learning-Based Optimal Control of Nonlinear Systems.

Traditional reinforcement learning (RL) methods for optimal control of nonlinear processes often face challenges, such as high computational demands, long training times, and difficulties in ensuring the safety of closed-loop systems during training. To address these issues, this work proposes a safe transfer RL (TRL) framework. The TRL algorithm leverages knowledge from pretrained source tasks to accelerate learning in a new, related target task, significantly reducing both learning time and computational resources required for optimizing control policies.

Histone MARylation regulates lipid metabolism in colorectal cancer by promoting IGFBP1 methylation.

In the global health community, colorectal cancer (CRC) is a major concern, with a high rate of incidence. Mono-ADP-ribosylation (MARylation) is a type of epigenetics and recognized as one of the causes of CRC development and progression. Although the modification level and target proteins in CRC remain unclear, it has been found that MARylation of arginine-117 of histone 3 (H3R117) promotes the proliferation, upregulates methylation of tumor suppressor gene, and is tightly associated with the metabolic processes in LoVo cells.

Aerobic exercise improves astrocyte mitochondrial quality and transfer to neurons in a mouse model of Alzheimer's disease.

Mitochondrial dysfunction is a well-established hallmark of Alzheimer's disease (AD). Despite recent documentation of transcellular mitochondrial transfer, its role in the pathogenesis of AD remains unclear. In this study, we report an impairment of mitochondrial quality within the astrocytes and neurons of adult 5 × FAD mice.

Integrated multimodal cell atlas of Alzheimer's disease.

Alzheimer's disease (AD) is the leading cause of dementia in older adults. Although AD progression is characterized by stereotyped accumulation of proteinopathies, the affected cellular populations remain understudied. Here we use multiomics, spatial genomics and reference atlases from the BRAIN Initiative to study middle temporal gyrus cell types in 84 donors with varying AD pathologies.

Transport of β-amyloid from brain to eye causes retinal degeneration in Alzheimer's disease.

The eye is closely connected to the brain, providing a unique window to detect pathological changes in the brain. In this study, we discovered β-amyloid (Aβ) deposits along the ocular glymphatic system in patients with Alzheimer's disease (AD) and 5×FAD transgenic mouse model. Interestingly, Aβ from the brain can flow into the eyes along the optic nerve through cerebrospinal fluid (CSF), causing retinal degeneration.

Molecular and spatial signatures of human and rat corpus cavernosum physiopathological processes at single-cell resolution.

The composition and cellular heterogeneity of the corpus cavernosum (CC) microenvironment have been characterized, but the spatial heterogeneity at the molecular level remains unexplored. In this study, we integrate single-cell RNA sequencing (scRNA-seq) and spatial transcriptome sequencing to comprehensively chart the spatial cellular landscape of the human and rat CC under normal and disease conditions. We observe differences in the proportions of cell subtypes and marker genes between humans and rats.

BIN1 deficiency enhances ULK3-dependent autophagic flux and reduces dendritic size in mouse hippocampal neurons.

Genome-wide association studies identified variants around the (bridging integrator 1) gene locus as prominent risk factors for late-onset Alzheimer disease. In the present study, we decreased the expression of BIN1 in mouse hippocampal neurons to investigate its neuronal function. knockdown via RNAi reduced the dendritic arbor size in primary cultured hippocampal neurons as well as in mature Cornu Ammonis 1 excitatory neurons.

CpG Island Definition and Methylation Mapping of the T2T-YAO Genome.

Precisely defining and mapping all cytosine (C) positions and their clusters, known as CpG islands (CGIs), as well as their methylation status, are pivotal for genome-wide epigenetic studies, especially when population-centric reference genomes are ready for timely application. Here, we first align the two high-quality reference genomes, T2T-YAO and T2T-CHM13, from different ethnic backgrounds in a base-by-base fashion and compute their genome-wide density-defined and position-defined CGIs. Second, by mapping some representative genome-wide methylation data from selected organs onto the two genomes, we find that there are about 4.

Magnetic Stimulation of Gigantocellular Reticular Nucleus with Iron Oxide Nanoparticles Combined Treadmill Training Enhanced Locomotor Recovery by Reorganizing Cortico-Reticulo-Spinal Circuit.

Background: Gigantocellular reticular nucleus (GRNs) executes a vital role in locomotor recovery after spinal cord injury. However, due to its unique anatomical location deep within the brainstem, intervening in GRNs for spinal cord injury research is challenging. To address this problem, this study adopted an extracorporeal magnetic stimulation system to observe the effects of selective magnetic stimulation of GRNs with iron oxide nanoparticles combined treadmill training on locomotor recovery after spinal cord injury, and explored the possible mechanisms.

Effects of nanoselenium on the performance, blood indices, and milk metabolites of dairy cows during the peak lactation period.

To compare the impact of nanoselenium and sodium selenite on the performance, blood indices, and milk metabolites of dairy cows during the peak lactation period, two groups of dairy cows under the same conditions were selected as the control group (CON group) and treatment group (NSe group) for a 38-day (10 days for adaptation and 28 days for sampling) experiment. The control group (CON) was provided a basal diet +3.3 g/d of sodium selenite (purity1%), whereas the nanoselenium group (NSe) was offered the same diet +10 mL/d of nanoselenium (selenium concentration 1,500 mg/L).

Enhancing color saturation in photonic glasses through optimized absorption.

Photonic glasses, isotropically assembled nanoparticles with short-range correlation, can produce angle independent structural colors. They show broader reflectance spectra and lower saturated colors, compared to photonic crystals. Low color saturation creates barriers for photonic glasses to be used for coatings, cosmetics, and colors.

Elucidation of the molecular mechanism of the breakage-fusion-bridge (BFB) cycle using a CRISPR-dCas9 cellular model.

Chromosome instability (CIN) is frequently observed in many tumors. The breakage-fusion-bridge (BFB) cycle has been proposed to be one of the main drivers of CIN during tumorigenesis and tumor evolution. However, the detailed mechanisms for the individual steps of the BFB cycle warrants further investigation.
