Hormonal control of programmed cell death/apoptosis.

Apoptosis or programmed cell death is a physiological form of cell death that occurs in embryonic development and during involution of organs. It is characterized by distinct biochemical and morphological changes such as DNA fragmentation, plasma membrane blebbing and cell volume shrinkage. Many hormones, cytokines and growth factors are known to act as general and/or tissue-specific survival f...

Hormonal regulation of the death commitment in programmed cell death of the silkworm anterior silk glands.

During larval-pupal transformation, the anterior silk glands (ASGs) of the silkworm Bombyx mori undergo programmed cell death (PCD) triggered by 20-hydroxyecdysone (20E). Under standard in vitro culture conditions (0.3 ml of medium with 1 μM 20E), ASGs of the fourth-instar larvae do not undergo PCD in response to 20E. Similarly, larvae of the fifth instar do not respond to 20E through day 5 of ...

Genetic control of programmed cell death in Drosophila melanogaster.

Apoptosis is a genetically controlled form of cell death that is an important feature of animal development and homeostasis. The genes involved in the control and execution of apoptosis are conserved throughout evolution. However, the actual molecular mechanisms used by these genes vary from species to species. In this review, we focus on the genetic components of apoptosis in the fruit fly Dro...

Control of programmed cyclin destruction in a cell-free system

To ask what controls the periodic accumulation and destruction of the mitotic across the cell cycle, we have developed a cell-free system from clam embryos that reproduces several aspects of cyclin behavior. One or more rounds of cyclin proteolysis and resynthesis occur in vitro, and the destruction of the cyclins is highly specific. The onset, duration, and extent of cyclin destruction and the...
