Summary: PIWI-interacting RNAs (piRNAs) are short molecules found in various species, with the main function of monitoring and protecting the genome from transposons. They have limited bioinformatics resources compared to microRNAs (miRNAs). This review provides an overview of piRNA-specific and non-specific databases, computational models, and their role in disease associations, particularly in cancer and neurodegenerative conditions.

Summary: This study reveals the regulation of RNA and protein abundance in genes with somatic copy number alterations (SCNAs), providing insights into gene regulation. Protein complex genes are primarily regulated at the protein level, while non-complex genes are primarily regulated at the RNA level. Interestingly, genes in the same pathway show similar levels of RNA and protein regulation, with certain pathways showing stronger regulation at either the protein level or the RNA level.

Summary: In this study, a new method called agoTRIBE is developed to comprehensively detect miRNA targets at the single-cell level. By fusing Argonaute2 protein with the RNA editing domain of ADAR2, the method allows sensitive single-cell RNA sequencing to identify miRNA targets. The results show that agoTRIBE can identify functional miRNA targets and obtain transcriptome-wide measurements of RNA abundance.

Summary: RNA interference (RNAi) is a gene regulatory and defense mechanism activated through calcium signaling, involving RNA-dependent RNA polymerase and Bifunctional nuclease to combat virus intrusion. Knockdown/knockout of Ca2+-related genes increases susceptibility to various viruses, indicating the importance of these genes in plant antiviral defense. Geminivirus V2 protein disrupts the calmodulin-CAMTA3 interaction to counteract RNAi defense, showing the versatility of host antiviral defense and viral counter-defense.

Summary: Animal African trypanosomiasis (AAT) is a severe, wasting disease affecting domestic livestock and diverse wildlife, predominantly caused by Trypanosoma congolense and T. vivax. However, due to challenges in genetic modifications, research on the pathogenic stages is limited, hindering the understanding of these parasites' biology. The development of tools for T. congolense, including gene tagging, knockout, transgene expression, and inducible gene knockdown, will greatly aid in further research on AAT and T. congolense biology.

Summary: The study evaluated whether hippocampal spindles and barques are markers of epileptogenicity in epilepsy patients. The results show that both spindles and barques are normal entities in the hippocampal intracranial electroencephalogram and do not indicate epileptogenic properties. Understanding this is crucial for the correct interpretation of epilepsy surgery evaluations and the selection of appropriate surgical treatments.

Summary: The neural crest transcription factor BRN3A is essential for melanoma cell proliferation and survival. The mechanism underlying its aberrant expression is unknown. This study revealed that the epigenetic regulator HDAC2 plays a key role in the expression of BRN3A in melanocytes and melanoma cells. Inhibition of HDAC2 increased BRN3A expression, highlighting the importance of epigenetic mechanisms in regulating melanoma oncogenes.

Summary: The skin of adult mammals protects against various damages, with dysfunction of melanocytes and melanocyte-producing stem cells potentially leading to melanoma. The inducible Cre-loxP-system is a promising tool for studying melanocytic cells in vivo. Genes associated with neural cells are also expressed in melanocytic cells, suggesting potential for modulating melanocytic cells using specific promoters. New mouse models were presented to study and potentially modify adult melanocytic cells in vivo.

Summary: Modifications in nuclear structures of cells play a role in diseases, including cancer. The role of nuclear lamina and related proteins in malignant melanoma is unclear. This study investigates the functional effects of dysregulated nuclear lamin B1 (LMNB1) and its nuclear receptor (LBR). It reveals their involvement in nuclear processes and their impact on senescence and chromatin state in melanoma cells. These findings suggest that LMNB1 and LBR are functionally relevant for melanoma progression.

Summary: THz frequency range is considered suitable for developing new bio-analytical methods due to the presence of THz-excited vibrational modes in biomacromolecules. In this study, a scalable THz metamaterial-based biosensor was used to investigate DNA samples at multiple frequencies. The results showed that the resonance frequency shift of the metamaterial depended on the presence of DNA and varied with frequency. The experiments demonstrated a significant difference in the power function between dsDNA and ssDNA, indicating an advantage for dsDNA detection and increased sensitivity at higher frequencies.
