Abstract Apoptosis is a sequential order of cell death occurring regularly to ensure a homeostatic balance between the rate of cell formation and cell death. However, a misplaced of this balancing function can contribute to an abnormal cell growth / proliferation or autoimmune disorders etc. Apoptosis is therefore said to be crucial from the point of development of an embryo throughout the growth of an organism contributing to the renewal of tissues and also the getting rid of inflammatory cells. This review seeks to elaborate on the recent overview of the mechanism involved in apoptosis, some element and signal contributing to its function and inhibition together with how their malfunction contribute to a number of cancer related cases.

Gall Inducer

Insect induced galls are not known from bryophytes. Here we report the first occurrence of such galls from thalli of a neotropical liverwort, Monoclea gottschei subsp. elongata (Marchantiophyta: Monocleaceae) from Peru. This is also the first report of animal-induced galls formed in modern thalloid liverworts. The gall-inducer is a species of the family Agromyzidae (Diptera). The galls are swellings, but are otherwise indistinguishable from intact thalli as their surface is neither ornamented nor sclerotized. The histology of the galls, however, suggested that abnormal cell growth and some differentiation occurred in the parenchymatous cells of the thalli during gall formation.
