Dissecting cellular senescence and SASP in Drosophila
Cellular senescence can act as both tumor suppressor and tumor promoter depending on the cellular contexts. On one hand, premature senescence has been considered as an innate host defense mechanism against carcinogenesis in mammals. In response to various stresses including oxidative stress, DNA damage, and oncogenic stress, suffered cells undergo irreversible cell cycle arrest, leading to tumo...
متن کاملChecks and Balances in Neuromodulation
Neuromodulators such as monoamines and peptides play important roles in activating and reconfiguring neural networks to allow behavioral flexibility. While the net effects of a neuromodulator change the network in a particular direction, careful studies of modulatory effects reveal multiple cases where a neuromodulator will activate functionally opposing mechanisms on a single neuron or synapse...

Checks and balances for the iron bank.
The RNA-binding iron regulatory proteins IRP1 and IRP2 are inactivated by either Fe-S cluster insertion or protein degradation mediated by the E3 ligase component FBXL5. However, the mechanisms for coordination between Fe-S cluster assembly, FBXL5, and IRP1/IRP2 activity are poorly defined. A new study reveals that FBXL5 plays a critical role in limiting IRP1 and IRP2 overaccumulation when cyto...
