Molecular genetic control of leaf lifespan in plants - A review

Leaf senescence constitutes the last stage of leaf development in plants and proceeds through a highly regulated program in order to redistribution of micro- and macro-nutrients from the senescing leaves to the developing/growing plant organs. Initiation and progression of leaf senescence is accompanied by massive sequential alterations at various levels of leaf biology including leaf morpholog...

Lifespan of neurons is uncoupled from organismal lifespan.

Neurons in mammals do not undergo replicative aging, and, in absence of pathologic conditions, their lifespan is limited only by the maximum lifespan of the organism. Whether neuronal lifespan is determined by the strain-specific lifetime or can be extended beyond this limit is unknown. Here, we transplanted embryonic mouse cerebellar precursors into the developing brain of the longer-living Wi...

Toxicity and lifespan extension

The RB pathway is one of the best-studied and most frequently altered pathways leading to loss of proliferative control in cancer. it can be disrupted by a variety of means including, but not limited to, epigenetic silencing, allelic loss or mutation of RB1. in some cancers including breast cancer, amplification of the CCND1 gene or overexpression of cyclin D1 is commonly observed.1 in others, ...
