Aphid lineages can be rendered infertile as a consequence of heat-induced elimination of their resident Buchnera [ 28], and field populations of A. pisum exposed to naturally occurring high temperatures undergo a decline in the number of bacteriocytes, reflecting the decline of the Buchnera population within heat-stressed aphid hosts [ 29].
It is worth pointing out that the efficacy of NFs in promoting SCD1 expression at both mRNA and protein level seemed to undergo a decline in the higher invasive and metastatic breast cancer cells (MDA-MB-231), if compared with MCF-7 cells.
This sub-population is the equivalent of the population remaining in the nest in the experiment where ants are prevented from returning, as it also undergoes a decline towards zero, when all ants in the colony would have been observed leaving the nest at least once.
