Abstract
The aim of the Special Issue "Acta Biochimica Polonica Reviews | 2023-2024" published in Acta Biochimica Polonica was to gather review articles from various research areas, focusing on cellular and molecular biology, and biomedicine. This editorial paper provides a concise overview of four publications published within the frames of this Special Issue.Plant transcriptomes are highly complex entities shaped by a multitude of stressors in a spatiotemporally heterogeneous manner (Imadi et al., 2015). Numerous abiotic stressors represent part of the normal ecological niche to which plants are adapted, often triggering constitutive or primed stress-response programs. Two papers published in the Special Issue, the first (Rurek, 2025) and the third (Rurek and Smolibowski, 2024), provide a deepened meta-analysis of differences in plant transcriptomes under the impact of various stressors and across diverse vegetative and generative organs and tissues. Data were taken from numerous model, crop and medicinal plant species, and from various transcriptomic platforms, including single cell and spatial RNA-seq (Peirats-Llobet et al., 2023;Wang et al., 2024;Guo et al., 2025).The enriched gene ontology terms from affected gene families and the respective transcription factors were compared. The supplementary data in both papers provide summary of quantitative alterations in gene expression patterns and details on experimental conditions. In their review, Rurek and Smolibowski (2024) compared dynamic transcriptomic responses to selected abiotic and biotic stressors (Wang et al., 2020). Stress responses involved both species/stressor-specific but also shared gene families (coding mostly photosynthetic proteins and secondary metabolism enzymes).In turn, Rurek (2025) aimed to characterize the most relevant spatiotemporal transcriptomic responses in selected vegetative and generative plant organs and tissues in the developmental context (Huang et al., 2016). The dynamicity of organ/tissue-specific responses was also compared in the context of the complexity and diversity of recently characterized plant genomes and transcriptomes. The specificity of organ/tissue-specific transcriptomes related to the over-representation of certain gene families and transcription factors was also emphasized. In addition, the perspectives for the application of medicinal plant species in industrial synthesis of valuable secondary metabolites were outlined based on organ-specific transcriptomic responses (Guo et al., 2021).From the reviews by Rurek and Smolibowski (2024) and Rurek (2025), the relevance of current plant transcriptomic studies both for basic research as well as for agriculture can be visioned. Functional analyzes would allow for better characterization of stress-responsive genes and less-known stress acclimatory mechanisms. On this basis, more stress-resistant crop cultivars could be designed in the future, based on advanced tools of plant biotechnology (Sriboon et al., 2010;Liu et al., 2024). Such actions should also benefit more from plant metabolome heterogeneity. More consistent usage of the potential of medicinal species in the synthesis of pharmaceutically important compounds may help to combat a range of lifestyle-related diseases.Modulation of the gut microbiome is another promising option to deal with the fatal increase in lifestyle-related diseases. The second paper in the Special Issue (Gofron et al., 2024) provides the meta-analysis of the complex effects of Akkermansia muciniphila (A. municiphila) on human health and their therapeutic applications. This facultatively anaerobic, gram-negative microbial species, initially isolated in 2004, colonizes the mucosa of the colon and rectum crypts and specializes in mucin degradation. Intensity of crypt colonisation by A. muciniphila correlates with the increased likelihood of colorectal cancer (Derrien et al., 2010;Nath and Mukherjee, 2014). However, available data also indicate the participation of A. municiphila in cobalamin biogenesis and in the maintenance of intestinal and cardiovascular health; these bacteria hamper endothelium inflammation and atherosclerosis (Shin et al., 2014;Li et al., 2016;Mok et al., 2020). By various cellular and molecular mechanisms, they control body weight and cardiovascular disorders, including atrial fibrillation, and can be used in obesity therapy (Dao et al., 2016;Depommier et al., 2019;Luo et al., 2022). A. municiphila also participates in the biogenesis of the intestinal mucosa layer and in the host protection against several inflammatory diseases (Qu et al., 2021).However, because of the limited number of reports, the interconnections between these activities and their general effects on human welfare need further exploration. In addition, the safety and potential of consuming living cultures of A. municiphila to maintain their positive cardiovascular effects, as well as more specialized studies on the impact of A. municiphila on the circulatory system should be investigated.For a long time, mitochondria were mainly regarded as the centers of bioenergetical processes and cellular metabolism. Novel aspects of mitochondria function include their participation in cytoprotection, cellular senescence, tumorigenesis, fibrosis and inflammatory responses (Li et al., 2020;Barrera et al., 2021;Chapa-Dubocq et al., 2023;Szabo and Szewczyk, 2023). The fourth publication of this Issue, a mini-review by Szewczyk ( 2024), focuses on recent findings concerning the role of mitochondrial K-dependent (mitoK) channels in the regulation of mitochondrial and cellular physiology. The discovery of mitoK channels in 1991 (Inoue et al., 1991), although initially underestimated, led to their recognition as crucial players in multiple aspects of mitochondrial biogenesis across various taxa (Koszela-Piotrowska et al., 2009;Laskowski et al., 2015;Szabo and Szewczyk, 2023). In this paper, the research of multiple mitochondrial K-dependent...
