[Letter to the Editor] DNA Fragmentation Is Not Associated with Apoptosis in Zerumbone-induced HepG2 Cells
Zerumbone is a cytotoxic compound isolated from the herbal plant, Zingiber zerumbet Smith, which exhibits antitumor activity [1-2], anti-inflammatory effects and possesses anti-proliferative potentials in a variety of cell lines [3-4]. DNA fragmentation indicates an early event of apoptosis leading to cell death due to the absence of new cellular proteins synthesizing for cell survival. Previou...
متن کاملNucleoplasmin regulates chromatin condensation during apoptosis.
Although chromatin condensation is one of the hallmarks of apoptosis, its relationship with DNA fragmentation has been controversial. We show here that apoptotic chromatin condensation is regulated by nucleoplasmin, a protein that decondenses sperm chromatin during male pronuclear assembly. In Xenopus egg extracts, nucleoplasmin is tyrosine-dephosphorylated during apoptosis. This dephosphorylat...
متن کاملTranscriptional coactivator PC4, a chromatin-associated protein, induces chromatin condensation.
Human transcriptional coactivator PC4 is a highly abundant multifunctional protein which plays diverse important roles in cellular processes, including transcription, replication, and repair. It is also a unique activator of p53 function. Here we report that PC4 is a bona fide component of chromatin with distinct chromatin organization ability. PC4 is predominantly associated with the chromatin...

متن کاملCondensation of the chromatin at the membrane of an apoptotic nucleus is not associated with activation of an endonuclease.
A current hypothesis holds that chromatin fragmentation into oligonucleosomal patterns is an early event during apoptosis. In contrast, induction of apoptosis in cultured hepatocytes by TGF-beta 1 was not associated with DNA fragmentation into oligonucleosomes in hepatocyte monolayers and apoptotic fragments. For a more rigorous test of the hypothesis we performed a number of experiments. We co...
