Abstract

Non-coding RNAs (ncRNAs) regulate gene expression through transcriptional, post-transcriptional, and epigenetic mechanisms, shaping hallmarks of cancer, including metastasis, therapy resistance, and relapse. Carcinogenesis arises when aberrant ncRNA networks initiate malignant transformation and sustain oncogenic changes through epigenetic modifications, shifts in cell identity, failures in genome protection, metabolic changes, and alterations in the tumour microenvironment. Environmental exposures, combined with chronic inflammation, reorganise these networks early on, leading to the formation of premalignant fields and persistent epigenetic changes. The four major ncRNA classes, microRNAs (miRNAs), long non-coding RNAs (lncRNAs), circular RNAs (circRNAs), and PIWI-interacting RNAs (piRNAs) function as either oncogenes or tumour suppressors depending on the specific cancer type. Their stability, cell-type-specific expression, and presence in biofluids make them suitable candidates for biomarker discovery and liquid biopsy applications. Therapeutic strategies now include antisense oligonucleotides, small interfering RNAs, synthetic miRNA mimics, RNA aptamers, and aptamer-siRNA conjugates, which can either inhibit oncogenic ncRNAs or restore tumour-suppressive regulatory networks. CRISPR-based ncRNA modulation, including Cas9-mediated locus editing, CRISPR interference/activation, and Cas13-mediated transcript targeting, remains largely investigational because delivery, off-target activity, and an incomplete understanding of ncRNA context dependence continue to limit translation. High-throughput sequencing, single-cell transcriptomics, and computational modelling have accelerated the identification of cancer-related ncRNAs and elucidated their biological functions. This review examines how different types of ncRNAs contribute to cancer initiation, progression, and treatment resistance, and assesses their potential as diagnostic markers, prognostic factors, and therapeutic targets.

Environmental Risk Assessment and Confinement of Genetically Engineered Trees with an Emphasis on Vegetative Reproduction.

Genetic engineering (GE) and gene editing may endow traits to trees such as increased biomass and the production of novel biomaterials. Long-lived organisms such as trees might be subject to biotechnology-related risks that could be different than those of annual row crops. Those risks could be relevant to production in engineered plantations and beyond plantations to natural forests. Therefore, appropriate risk regulation is important to assure biosafety of commercialized engineered trees. In addition to gene flow via sexual reproduction, vegetative reproduction might play an additional role in environmental "exposure" risk relative to transgene dispersal in GE tree plantations. While vegetative reproduction is beneficial for preserving desired genetic traits during tree propagation, it may lead to proximal clonal spread in the field. Although the environmental risks associated with vegetative reproduction of GE trees are recognized in commercial forestry, there are few field-based environmental risk assessment (ERA) studies on dispersal risks of self-propagated GE trees. GE or gene editing of target genes involved in the vegetative propagation processes may be useful to mitigate environmental risks of clonal spread through vegetative reproduction. This review provides updates for recent field test results of GE and gene edited trees. Gene candidates related to vegetative reproduction including adventitious shooting (AS) and adventitious rooting (AR) are discussed herein as a means to mitigate unintended clonal spread from GE tree plantations.

Immunogenic cell death in CNS diseases: From bench to bedside.

The central nervous system (CNS) harbors a distinct immune memory programming system, wherein immunogenic cell death (ICD) acts as a pivotal signaling hub. A spectrum of insults, from systemic metabolic dysfunction to local protein aggregation and ionic dyshomeostasis, can provoke ICD in neurons, glia, and resident immune cells. This process orchestrates the release of damage-associated molecular patterns (DAMPs) from distinct subcellular compartments. These DAMPs synergistically initiate both innate trained immunity (TI), characterized by profound metabolic-epigenetic reprogramming, and antigen-specific adaptive immune responses that traverse the blood-brain barrier. Together, these pathways constitute an integral network of central immune surveillance. Crucially, this ICD-driven immune programming exhibits a striking functional dichotomy depending on the pathological context. In non-neoplastic conditions such as neural injury and neurodegenerative diseases, uncontrolled ICD signaling can establish a pathological trained immune memory, driving a self-perpetuating cycle of chronic neuroinflammation and tissue damage. Conversely, within the tumor microenvironment of malignancies like glioma, the adaptive immune responses elicited by ICD are frequently subverted by potent immunosuppressive mechanisms, culminating in tumor immune escape. This review dissects the differential regulatory mechanisms of ICD-mediated immune memory in CNS tumors versus non-tumor diseases. We aim to elucidate the molecular switches that govern the transition of this immune program from a beneficial, compensatory state to a pathological, detrimental phenotype. By exploring emerging therapeutic strategies, including gene editing, nanomaterials, and bioactive phytochemicals that precisely target ICD pathways, we provide a theoretical framework for understanding CNS immune homeostasis and for the rational design of precision immunotherapies.
