Chromatin immunoprecipitation assay (ChIP) has been frequently used to determine whether a transcriptional regulator can bind to a specific DNA element in the chromatin content of cells. Here, we describe a detailed protocol for this assay with hands-on tips based on our own experience in working on the transcriptional regulator and tumor suppressor p53.

DNA replication ensures the precise transmission of genetic information from parent to daughter cells. In eukaryotes, this process involves the replication of every base pair within a highly complex chromatin environment, encompassing multiple levels of chromatin structure and various chromatin metabolic processes. Recent evidence has demonstrated that DNA replication is strictly regulated in both temporal and spatial dimensions by factors such as 3D genome structure and transcription, which is crucial for maintaining genomic stability in each cell cycle.

SUMOylation is a protein modification process that involves the covalent attachment of a small ubiquitin-like modifier (SUMO) to a specific lysine residue on the target protein. This modification can influence the function, localization, stability, and interactions of proteins, thereby regulating various cellular processes. Altering the SUMOylation of certain proteins is expected to be a potential approach for treating specific cancers and diseases.

Chinese cabbage is an important vegetable in southern China. Excessive nitrogen fertilizer application can lead to the accumulation of nitrate in edible organs, which affects food value. Hence, the cultivation of varieties with high nitrogen utilization efficiency (NUE) and low nitrate accumulation is essential for molecular breeding.

Moderate UV-B promotes plant growth, but excessive UV-B inhibits plant development. The induction mechanism of how CtWD40-6 responds to UV-B is still unclear in safflower. Our results showed that CtWD40-6 is expressed at the top of safflower leaves and is strongly induced by UV-B.
