Addition of multiple ubiquitin groups to a protein, forming a ubiquitin chain.

The process during Drosophila embryogenesis whereby the ectodermal cells of the lateral epithelium stretch in a coordinated fashion to internalize the amnioserosa cells and close the embryo dorsally.

Any biological process that results in permanent cessation of all vital functions of a cell. A cell should be considered dead when any one of the following molecular or morphological criteria is met: (1) the cell has lost the integrity of its plasma membrane; (2) the cell, including its nucleus, has undergone complete fragmentation into discrete bodies (frequently referred to as apoptotic bodies). The cell corpse (or its fragments) may be engulfed by an adjacent cell in vivo, but engulfment of whole cells should not be considered a strict criteria to define cell death as, under some circumstances, live engulfed cells can be released from phagosomes (see PMID:18045538).

Any process that activates, maintains or increases the rate of autophagy. Autophagy is the process in which cells digest parts of their own cytoplasm.

A series of molecular signals in which a stress-activated protein kinase (SAPK) cascade relays one or more of the signals.

Any process that modulates I-kappaB kinase/NF-kappaB signaling.

Innate immune responses are defense responses mediated by germline encoded components that directly recognize components of potential pathogens.

Any process that stops, prevents, or reduces the frequency, rate or extent of the Notch signaling pathway.

Any process that stops, prevents, or reduces the frequency, rate or extent of the Notch signaling pathway.

Any process that modulates the frequency, rate or extent of the antiviral response of a cell or organism.

All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
