A well-constructed pollen wall is essential for pollen fertility, which relies on the contribution of tapetum. Our results demonstrate an essential role of the tapetum-expressed protein phosphatase 2A (PP2A) B'α and B'β in pollen wall formation. The b'aβ double mutant pollen grains harbored sticky remnants and tectum breakages, resulting in failed release.

Purpose: Nano-drug delivery systems (NDDS) have become a promising alternative and adjunctive strategy for lung cancer (LC) treatment. However, comprehensive bibliometric analyses examining global research efforts on NDDS in LC are scarce. This study aims to fill this gap by identifying key research trends, emerging hotspots, and collaboration networks within the field of NDDS and LC.

Chronic obstructive pulmonary disease (COPD) is a prevalent chronic inflammatory airway disease with high incidence and significant disease burden. R-loops, functional chromatin structure formed during transcription, are closely associated with inflammation due to its aberrant formation. However, the role of R-loop regulators (RLRs) in COPD remains unclear.

Clear cell renal cell carcinoma (ccRCC) is a highly malignant tumor characterized by a significant propensity for recurrence and metastasis. DNA methylation has emerged as a critical epigenetic mechanism with substantial utility in cancer diagnosis. In this study, multi-omics data were utilized to investigate the target genes regulated by the transcription factor MYC-associated zinc finger protein (MAZ) in ccRCC, leading to the identification of thymidine phosphorylase (TYMP) as a gene with notably elevated expression in ccRCC.

The nucleolus is a major subnuclear compartment where ribosomal DNA (rDNA) is transcribed and ribosomes are assembled. In addition, recent studies have shown that the nucleolus is a dynamic organizer of chromatin architecture that modulates developmental gene expression. rDNA gene units are assembled into arrays located in the p-arms of five human acrocentric chromosomes.
