Modulators of the hedgehog signaling pathway

Bioorganic & Medicinal Chemistry, 2010
Since its discovery by C. Nüsslein-Volhard and E. F. Wieschaus, hedgehog (hh) signaling has come a long way. Today it is regarded as a key regulator in embryogenesis where it governs processes like cell proliferation, differentiation, and tissue patterning. Furthermore, in adults it is involved in the maintenance of stem cells, and in tissue repair and

Modulation of Cellular Signals by Calpain

Annals of the New York Academy of Sciences, 1992
Calpain, an inactive proenzyme, translocates from the cytosol to the membrane upon binding calcium, and is activated at the membrane in the presence of calcium and PIP2. Activated calpain is very unstable and presumably used only once. Thus the primary targets of calpain are considered to be membrane or membrane-associated proteins.

Delta Modulation of Data Signals

IEEE Transactions on Communications, 1974
This paper is an analytical study to determine the performance of single-integration delta-modulation (\DeltaM) encoders with inputs which are various voice-band data signals. Signal-to-quantizing noise ratios S/N are calculated for \DeltaM bit rates from 16 to 96 K bits/s.

Modulation of BMP signalling by integrins

Biochemical Society Transactions, 2016
The bone morphogenetic protein (BMP) pathway is a major conserved signalling pathway with diverse roles in development and homeostasis. Given that cells exist in three-dimensional environments, one important area is to understand how the BMP pathway operates within such complex cellular environments.
