TLDR
Evidence is presented that in Drosophila, activation of the Ras pathway specifically inhibits the proapoptotic activity of the gene head involution defective (hid), and it is shown that MAPK phosphorylation sites in Hid are critical for this response.About:

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.

bantam Encodes a Developmentally Regulated microRNA that Controls Cell Proliferation and Regulates the Proapoptotic Gene hid in Drosophila
TL;DR: It is reported that the bantam gene of Drosophila encodes a 21 nucleotide microRNA that promotes tissue growth and identifies the pro-apoptotic gene hid as a target for regulation by bantam miRNA, providing an explanation for bantam's anti-APoptotic activity.

Cell survival promoted by the Ras-MAPK signaling pathway by transcription-dependent and -independent mechanisms.
Azad Bonni,Anne Brunet,Anne E. West,Sandeep Robert Datta,Mari A. Takasu,Michael E. Greenberg +5 more
TL;DR: The findings suggest that the MAPK signaling pathway promotes cell survival by a dual mechanism comprising the posttranslational modification and inactivation of a component of the cell death machinery and the increased transcription of pro-survival genes.

Cell death in development
TL;DR: This work focuses on the development and use of positron emission tomography for the diagnosis of central giant cell granuloma, a type of tumour that is difficult to treat with chemotherapy.

Programmed Cell Death in Animal Development and Disease
Yaron Fuchs,Hermann Steller +1 more
TL;DR: A growing body of work about the connections between apoptosis, stem cells, and cancer is explored, focusing on how apoptotic cells release a variety of signals to communicate with their cellular environment, including factors that promote cell division, tissue regeneration, and wound healing.

Targeted gene expression as a means of altering cell fates and generating dominant phenotypes.
Andrea H. Brand,Norbert Perrimon +1 more
TL;DR: The GAL4 system, a system for targeted gene expression that allows the selective activation of any cloned gene in a wide variety of tissue- and cell-specific patterns, has been designed and used to expand the domain of embryonic expression of the homeobox protein even-skipped.

Apoptosis in the pathogenesis and treatment of disease
TL;DR: In multicellular organisms, homeostasis is maintained through a balance between cell proliferation and cell death, and recent evidence suggests that alterations in cell survival contribute to the pathogenesis of a number of human diseases.

Akt Phosphorylation of BAD Couples Survival Signals to the Cell-Intrinsic Death Machinery
Sandeep Robert Datta,Henryk Dudek,Xu Tao,Shane C. Masters,Haian Fu,Yukiko Gotoh,Michael E. Greenberg +6 more
TL;DR: It is shown that growth factor activation of the PI3'K/Akt signaling pathway culminates in the phosphorylation of the BCL-2 family member BAD, thereby suppressing apoptosis and promoting cell survival.

Opposing Effects of ERK and JNK-p38 MAP Kinases on Apoptosis
TL;DR: The effects of dominant-interfering or constitutively activated forms of various components of the JNK-p38 and ERK signaling pathways demonstrated that activation of JNK and p38 and concurrent inhibition of ERK are critical for induction of apoptosis in these cells.

ras Oncogenes in Human Cancer: A Review
TL;DR: It appeared that ras gene mutations can be found in a variety of tumor types, although the incidence varies greatly and some evidence that environmental agents may be involved in the induction of the mutations.
