Title: Crosstalk between Dpp and Tor signaling coordinates autophagy-dependent midgut degradation
Author: Denton, D.; Xu, T.; Dayan, S.; Nicolson, S.; Kumar, S.
Abstract: The majority of developmentally programmed cell death (PCD) is mediated by caspase-dependent apoptosis; however, additional modalities, including autophagy-dependent cell death, have important spatiotemporally restricted functions. Autophagy involves the engulfment of cytoplasmic components in a double membrane vesicle for delivery to the lysosome. An established model for autophagy-dependent PCD is Drosophila larval midgut removal during metamorphosis. Our previous work demonstrated that growth arrest is required to initiate autophagy-dependent midgut degradation and Target of rapamycin (Tor) limits autophagy induction. In further studies, we uncovered a role for Decapentaplegic (Dpp) in coordinating midgut degradation. Here, we provide new data to show that Dpp interacts with Tor during midgut degradation. Inhibiting Tor rescued the block in midgut degradation due to Dpp signaling. We propose that Dpp is upstream of Tor and down-regulation promotes growth arrest and autophagy-dependent midgut degradation. These findings underscore a relationship between Dpp and Tor signaling in the regulation of cell growth and tissue removal.2019-01-01T00:00:00ZQCD evolution of the spin structure functions of the neutron and proton

Title: QCD evolution of the spin structure functions of the neutron and proton
Author: Schreiber, A.W.; Thomas, A.W.; Londergan, J.T.
Abstract: Models of the long-distance behavior of QCD can be used to make predictions for the twist-two piece of the current correlation function appearing in deep-inelastic scattering. The connection between the model predictions, valid at a four-momentum transfer squared Q2 of the order of 1 (GeV/c)2, and the data, collected at much higher Q2, is provided by perturbative QCD. We present here the details of a method, previously used for spin-averaged lepton scattering, applied to the spin-dependent case. We then use the method to make predictions for the spin structure functions gprotonl and gneutronl.1990-01-01T00:00:00ZThe place of work in a meaningful life
