Summary: Cancer disrupts lipid metabolism, leading to altered metabolism intermediates and contributing to abnormal growth and metastasis. The shift in lipid metabolism towards an increased presence of polyunsaturated fatty acids (PUFAs) in membrane phospholipids (PLs) also causes resistance to cancer therapy. The vulnerability of cancer cells to lipid peroxidation (LPO) and subsequent ferroptosis, a new form of regulated cell death, depends on adaptive lipidome remodeling, LPO patterns, and LPO scavenging ability. Understanding the molecular basis of altered lipid metabolism in cancer may offer new opportunities for overcoming cancer resistance.

Summary: Ferroptosis is a type of iron-dependent regulated necrosis induced by lipid peroxidation in cellular membranes. Polyunsaturated fatty acids associated with specific phospholipids are responsible for ferroptosis-inducing lipid peroxidation. Cells take up essential fatty acids from blood to produce PUFAs, which undergo lipid peroxidation through various pathways tightly regulated by metabolic and signaling pathways.

Summary: Green microalgae, such as Lobosphaera incisa, can accumulate neutral lipids under stress, including nitrogen starvation. This study identified a linoleate 13-lipoxygenase (LiLOX) in green algae, which is induced upon nitrogen starvation and localized in the stroma of plastids. LiLOX showed preferences towards the lipid class MGDG, suggesting its involvement in the degradation of the plastidic membrane.

Summary: Lipid peroxidation (LPO) plays a damaging role in chemodynamic therapy (CDT), and the effect of cell membrane unsaturation degree on CDT has not been explored. This study introduces a self-reinforcing CDT agent (OA@Fe-SAC@EM NPs) that promotes LPO by modulating the degree of membrane unsaturation. The agent consists of oleanolic acid (OA)-loaded iron single-atom catalyst (Fe-SAC)-embedded hollow carbon nanospheres encapsulated by an erythrocyte membrane (EM), enabling lipid peroxidation amplification-enhanced CDT.

Summary: Plant oxylipins are lipid-derived signaling molecules involved in regulating stress responses. OPDA and its metabolite JA are common oxylipins, but the occurrence of JA in plants is still debated. We studied the metabolism of oxylipins in the non-vascular plant P. patens and identified several compounds, including isobaric molecules to JA, after wounding. These findings will contribute to further understanding of the oxylipin-receptor interactions in P. patens.

Summary: High expression of CD38 leads to degradation of DHFR and increased susceptibility to ferroptosis. BMDMs from aged mice with high CD38 expression are more susceptible to ferroptosis, but this susceptibility can be reversed by NMN replenishment.

Summary: Our study showed that PUFAs accelerate the photodamage to PSII in Synechocystis cells, while monounsaturated fatty acids do not have this effect. PUFAs are specifically incorporated into the sn-2 position of PG molecules, a process that requires the involvement of acyl-ACP synthetase.

Summary: This study investigated the changes in membrane fatty acid composition and damage indices in two chickpea genotypes under cold stress. The results showed that the tolerant genotype exhibited higher levels of certain fatty acids and lower damage indices compared to the sensitive genotype, indicating enhanced tolerance to cold stress. The upregulation of carbonyl-detoxifying genes in the tolerant genotype was also associated with improved tolerance.

Summary: The skin's barrier function is crucial for maintaining skin homeostasis. Bioactive lipid mediators derived from n-3 and n-6 PUFAs play complex roles in skin diseases, including psoriasis. High intake of n-3 PUFAs has been shown to reduce the severity and frequency of psoriatic plaques.

Summary: This study compared the new variety of oil flax (Silesia) with already cultivated varieties in terms of plant productivity, oil content, fatty acid composition and significant secondary metabolites. It was found that the ratio of polyunsaturated fatty acids is associated with a better metabolic state of flaxseed, and thus with a higher nutritional value. Additionally, a number of specialized secondary metabolites characteristic of the flax studied were identified, which could be useful for chemotaxonomy.

Summary: Limited use of computer assisted semen analysis (CASA) for evaluating reptile sperm was observed. The study analyzed sperm kinematic variables in American crocodile semen samples and identified distinct subpopulations based on velocity, progressiveness, and oscillation. Variability among males in kinematic subpopulations suggests potential for future development of assisted reproduction techniques for crocodiles, utilizing CASA technology.

Summary: Sperm is a highly differentiated and polarized cell with two main structures: the head and the flagellum. Despite having the same function, there is a great diversity in the structure and performance of sperm cells. This diversity may be related to the mechanisms of transport, fertilization preparation, and interaction with the oocyte.

Summary: Good-quality sperm samples are essential for reproductive biotechnologies, and factors such as seasonality and social environment affect sperm quality in endangered gazelles. While seasonality plays a significant role in sperm quality across all three gazelle species, social factors seem to have a greater impact on dorcas gazelle.

Summary: Mammalian sperm show wide variation in morphology and physiology, especially in terms of ATP levels during capacitation and hyperactivation. The decrease in ATP levels is related to the development of hyperactivated motility and is steeper in species with higher levels of sperm competition. These findings suggest that ATP consumption is higher during capacitation and is associated with higher velocity and head displacement.

Summary: The expansion of urban environments and its impact on animals have led to an increase in urban ecology studies. However, it is often assumed but not properly investigated that rural populations serve as controls in comparing urban populations. This study used museum skulls of rodent species to assess the effect of anthropogenic disturbance and found that urban populations had higher morphological asymmetry compared to rural populations. However, there was no significant increase in asymmetry over time in rural populations, supporting the use of rural populations as controls in urban ecology studies.

Summary: The acquisition of fertilizing ability by mammalian spermatozoa, known as capacitation, is influenced by metabolic pathways and has variable effects in different species. Mouse sperm can produce ATP through multiple metabolic pathways, and the study focuses on a closely related species to compare its metabolic traits with laboratory strains. The steppe mouse, Mus spicilegus, demonstrated a similar response to capacitation as Mus musculus but also exhibited distinct metabolic features.

Summary: Sperm DNA integrity and chromatin status are important indicators of sperm quality, and they are closely related to sperm function, embryo development, and overall fertility. This study assessed the chromatin status and its possible correlation with DNA damage in different mouse species. The results showed that the chromatin status was generally normal across all three species, with minimal abnormal values. The DNA fragmentation varied between species, and there were correlations between chromatin staining and DNA fragmentation. Overall, chromatin compaction was high in all species, and the relationship between chromatin status and DNA integrity appeared to be related to levels of sperm competition among species.

Summary: The expansion of urban environments has led to increased studies on the phenotypic changes of animals. However, most studies have focused on a single urban center, and a comprehensive understanding of the effects of urbanization requires comparing urban populations of the same species across multiple cities. A meta-analysis of data from different cities revealed that morphology, physiology, and behavior of urban animals differ across cities, with greater differences observed in studies involving more cities and cities farther apart. It is important to conduct urban studies across diverse cities to understand urban adaptations in different ecological contexts.
