After 24 48 hours of exposure to the fermenticin HV6b, the epithelial tissue models retained only a low level of viability.
Viability showed greater variability at low levels of target cell viability.
Array CGH and sequencing revealed that this strain is a complex interspecific hybrid between S. uvarum, S. cerevisiae, and the recently described and sequenced species S. eubayanus (Libkind et al. 2011); its hybrid nature was further supported by its low levels of sporulation and spore viability, as is typical of hybrids (Greig et al. 2002).
However, these strains could have low levels of σE activity that contribute to viability.
While this level of suppression does not preclude the residual levels of RabX1 and RabX2 being sufficient for viability, the low levels of most Rab proteins normally makes them rather sensitive to knockdown, and hence these results potentially indicate that RabX1 and RabX2 are probably non-redundant, consistent with their differential location.
Aggregation can also appear in the form of intracellular inclusions, low cell/culture viability, or low levels of productivity.
Although 4E-BP1 is not necessarily indicative of all native Mec1 substrates, this result suggests that only low levels of kinase activity are essential for viability in rich media.
Whereas low levels of the E protein can cause loss of viability [49], at the same level, the reporter protein may be below the detection threshold of standard methods [7].
Similar to that of InFs, the viability of CAFs (which express low levels of laminin-332) was increased by MDA-MB-231 CM and integrin β4 induction, although the viability of CAFs was lower than that of InFs.
Often mutations that confer resistance have been shown to compromise virus viability resulting in extremely low levels of purified NA being obtained[8], [9].
