Summary: Glioblastoma is highly resistant to standard therapies and the durability of response to the best chemotherapy agent, Temozolomide, is often short-lived due to tumor resistance. The need for therapies that can provide synergy to chemoradiation is urgent, as adaptive resistance evolution in GBM is facilitated through treatment-induced epigenetic modifications. Understanding and targeting these epigenetic modifications associated with GBM resistance is a top priority.

Summary: The incidence of psoriasis is increasing over time, with recent studies pointing towards the importance of epigenetic modifications in its pathogenesis. Aberrant epigenetic patterns, including changes in DNA methylation, histone modifications and non-coding RNA expression, are observed in psoriatic skin. Reversing these epigenetic mechanisms has shown promise in improving psoriatic phenotypes, making epigenetic therapy a potential avenue for treating psoriasis.

Summary: Ceiling culture-derived preadipocytes (ccdPAs) and adipose-derived stem cells (ASCs) were isolated from human subcutaneous fat tissue and showed differences in adipogenic potential due to variations in methylation and histone modification levels of adipogenesis-related genes, such as PPARc, fatty acid-binding protein 4, and leptin. Genomewide epigenetic analysis revealed distinct patterns in CpG methylation and H3K4me3 modification between ccdPAs and ASCs, suggesting epigenetic mechanisms underlying adipogenic differentiation capabilities of these cell types.

Summary: The concept of epigenetics was first proposed in 1942. Chemical modifications on histones, DNA, and RNA have been identified as three key components of epigenetic modifications. These modifications play a crucial role in various biological processes and diseases, including cancer. With the advancement of sequencing technologies, scientists are now able to accurately map and quantify different types of epigenetic modifications in histones, DNA, and RNA, providing insights into gene regulation.

Summary: An intricate interplay between genetic and environmental factors contributes to the development of type 2 diabetes (T2D) and its complications. Metformin, a derivative of biguanide, exerts pleiotropic effects through multiple epigenetic modifications, which are reported in various organs, tissues, and cellular compartments. This review discusses the emerging evidence regarding metformin-mediated epigenetic modifications, their significance, potential applications, and future research directions.

Summary: The effects of neonicotinoid contamination on honey bees are controversial. A five-year study found that feeding honey bee colonies with imidacloprid in sugar syrup resulted in increased brood production, lower temperature variability, higher CO2 production, and more foragers. However, it did not affect adult bee numbers, hive temperatures, food stores, daily food acquisition, or colony survivorship.

Summary: The ability of honey bees to avoid food contaminated with common metal pollutants was investigated. The results showed that bees did not distinguish between contaminated and uncontaminated food, and only showed reduced intake and appetitive responses at high concentrations of lead and zinc. It was found that bees were unable to detect low concentrations of harmful metals like arsenic and lead in their food, indicating that trace metal pollution poses a major threat to pollinators.

Summary: Understanding the cumulative risk of chemical mixtures at environmentally realistic concentrations is crucial in honey bee ecotoxicology. Ecotoxicogenomics, specifically transcriptomics, can provide insights into the mechanisms underlying phenotypic responses and link them to population impacts. In this study, gene expression profiles of honey bee larvae exposed to the pesticide imidacloprid and acaricide thymol, both separately and in combination, were analyzed using RNA-seq. The separate and combined treatments had distinct gene expression profiles, affecting different signaling and metabolic pathways. The molecular signature of the mixture revealed additive interactions in stress responses and non-additive interactions in secondary responses. Novel impacts on eye development genes correlated with long-term defects in visual learning performance. Establishing mechanistic links between molecular and phenotypic responses is important when predicting the effects of chemical mixtures on populations.

Summary: Assessing individual foraging performance is crucial for environmental policy-making. We have developed a new autonomous field method using RFID to record honey bee flight ontogeny and foraging performance. By separating bee traffic into returning and exiting tunnels, we have overcome previous limitations of RFID systems caused by traffic jams and antennae coupling.

Summary: This study reveals that there are significant differences in mRNA transcripts between honeybee queens and workers during their larval development. These differences are generated by a flexible splicing system. Poly(A) tails are found to negatively regulate the expression of differentially expressed transcript isoforms (DEIs) involved in caste differentiation. The expression of isoforms is unique to each caste and varies at different developmental stages, indicating a dynamic relationship between isoform expression and developmental mechanisms.

Summary: Using a multiomics approach, we investigated the epigenomic landscapes of honey bee workers and queens during development, revealing distinct differences between the two castes. Genes involved in caste differentiation were regulated by multiple epigenomic systems, and manipulation of two candidate genes resulted in decreased weight and fewer ovarioles in newly emerged queens. These findings demonstrate the development of distinct epigenomic landscapes in worker and queen bees.

Summary: Biting and chewing insects, such as crickets, have a foregut with a crop that allows them to store and process food when they cannot find it. During a short period of starvation, the size of the salivary glands of crickets decreases, but they immediately increase in size upon feeding. The amines that stimulate gland secretion are stored in the zymogen cells instead of the parietal cells, indicating that feeding and starving can affect different parts of the digestive system.

Summary: The evolutionary history of animal cognition involves major transitions that opened up new possibilities for cognitive abilities. This article reviews and compares different explanations of these transitions. It argues that an important aspect of an evolutionary transition is that it changes what can be evolved, leading to differences in phenotypic spaces before and after the transition. The article proposes a framework for understanding cognitive evolution that focuses on how selection acts on the computational architecture of nervous systems.
