The nerve growth factor 35 years later
TLDR
The field of experimental embryology, which had been enthusiastically acclaimed in the mid-thirties, suffered from a sharp decrease in the enthusiasm that had inflamed the pioneers in this field, ever since R. G. Harrison delivered his celebrated lecture at the Royal Society in London in 1935.Abstract:
"Embryogenesis is in some way a model system. It has always been distinguished by the exactitude even punctitio, of its anatomical descriptions. An experiment by one of the great masters of embryology could be made the text of a discourse on scientific method. But something is wrong, or has been wrong. There is no theory of development in the sense in which Mendelism is a theory that accounts for the results of breeding experiments. There has therefore been little sense of progression or timeliness about embryological research. Of many papers delivered at embryological meetings, however good they may be in themselves . . . one too often feels that they might have been delivered five years beforehand without making anyone much the wiser, or deferred for five years without making anyone conscious of a great loss" (1). This feeling of frustration so incisively conveyed by these considerations by P. Medawar, pervaded, in the forties, the field of experimental embryology which had been enthusiastically acclaimed in the mid-thirties, when the upper lip of the amphibian blastopore brought this area of research to the forefront of the biological stage. The side branch of experimental neuroembryology, which had stemmed out from the common tree and was entirely devoted to the study of the tropic interrelations between neuronal cell populations and between these and the innervated organs and tissues, was then in its initial vigorous growth phase. It in turn suffered from a sharp decrease in the enthusiasm that had inflamed the pioneers in this field, ever since R. G. Harrison delivered his celebrated lecture on this topic at the Royal Society in London in 1935 (2). Although the alternate "wax and wane" cycles are the rule rather than the exception in all fields of human endeavor, in that of biological sciences the "wane" is all too often indicative of a justified loss of faith in the rational and methodical approach that had at first raised so much hope.

Cellular survival: a play in three Akts
TL;DR: The mechanisms by which survival factors regulate the PI3K/c-Akt cascade, the evidence that activation of the PI 3K/ c-AKT pathway promotes cell survival, and the current spectrum of c- akt targets and their roles in mediating c- Akt-dependent cell survival are reviewed.

Neurotrophins: roles in neuronal development and function.
Eric J. Huang,Louis F. Reichardt +1 more
TL;DR: Neurotrophins regulate development, maintenance, and function of vertebrate nervous systems, and control synaptic function and synaptic plasticity, while continuing to modulate neuronal survival.
Journal ArticleDOI
Programmed Cell Death in Animal Development
TL;DR: Because of the limited number of references allowed, the authors were unable to cite many important papers; they apologize to their authors.

Trk receptors: roles in neuronal signal transduction.
Eric J. Huang,Louis F. Reichardt +1 more
TL;DR: The most fascinating aspect of Trk receptor-mediated signaling is its interplay with signaling promoted by the pan-neurotrophin receptor p75NTR, which activates a distinct set of signaling pathways within cells that are in some instances synergistic and in other instances antagonistic to those activated by Trk receptors.
Journal ArticleDOI
Neurotrophin-regulated signalling pathways
TL;DR: Three rare human genetic disorders, which result in deleterious effects on sensory perception, cognition and a variety of behaviours, have been shown to be attributable to mutations in brain-derived neurotrophic factor and two of the Trk receptors.

Establishment of a noradrenergic clonal line of rat adrenal pheochromocytoma cells which respond to nerve growth factor.
TL;DR: A single cell clonal line which responds reversibly to nerve growth factor (NGF) has been established from a transplantable rat adrenal pheochromocytoma and should be a useful model system for neurobiological and neurochemical studies.

Close similarity of epidermal growth factor receptor and v- erb-B oncogene protein sequences
Julian Downward,Yosef Yarden,E. Mayes,G. Scrace,Nick Totty,P. Stockwell,Axel Ullrich,Joseph Schlessinger,Mike Waterfield +8 more
TL;DR: Six peptides derived from the human epidermal growth factor receptor very closely matches a part of the deduced sequence of the v-erb-B transforming protein of avian erythroblastosis virus (AEV).

The c-fms proto-oncogene product is related to the receptor for the mononuclear phagocyte growth factor, CSF 1
Charles J. Sherr,Carl W. Rettenmier,Rosalba Sacca,Martine F. Roussel,A. Thomas Look,E. Richard Stanley +5 more
TL;DR: The feline c-fms proto-oncogene product and the CSF-1 receptor are related, and possibly identical, molecules.

Simian sarcoma virus onc gene, v-sis, is derived from the gene (or genes) encoding a platelet-derived growth factor
Russell F. Doolittle,Michael W. Hunkapiller,Leroy Hood,Sushilkumar G. Devare,Keith C. Robbins,Stuart A. Aaronson,Harry N. Antoniades +6 more
TL;DR: The demonstrating of extensive sequence similarity between the transforming protein derived from the simian sarcoma virus onc gene, v-sis, and a human platelet-derived growth factor shows that this protein could be a factor active transiently during normal cell growth.
