Without a good means of studying reactivation, some MuHV-4 gene functions have been hard to define.
We have applied fluorimetric method to monitor aldehyde dehydrogenase (ALDH*) activity in human saliva samples to study inactivation, reactivation and inhibition of the enzyme.
Next, we established a homogeneous population of GFP-negative epiSCs, termed XiGFP epiSCs, in which the GFP transgene is located exclusively on the Xi, providing a basis to study the reactivation of the Xi by monitoring GFP expression.
To study the reactivation of humoral autoimmunity after immunoablative therapy, we analyzed the avidity of reappearing ACPA-IgG autoantibodies by dichotomizing patients according to their pre-transplantation ACPA-IgG level and corresponding reduction after immunoablative therapy ('ACPA responders' and 'ACPA nonresponders'; Figure 3a,b).
In the three T cell lines studied, host cell reactivation efficiency was directly related to the cells' abilities to repair cisplatin-damaged cellular DNA (correlation coefficient = 0.993).
Roelants et al. studied the ATCase reactivation resulting from Ty1 insertions and established that the transcription process is initiated in the LTR (Long Terminal Repeat) region of the Ty1 retrotransposon [ 8].
In this sense, a number of approaches have been studied for the reactivation of latently HIV-infected cells, including cytokines such us IL-2 and IL-7 or small molecules with pharmacological properties that allow them to access the viral reservoirs [ 2, 3].
Reactivation of the denatured TIM was initiated by diluting (at least 100-fold) the denaturated enzymes in media at pH 7.4 that contained 100 mM triethanolamine, 10 mM EDTA and 200 mM GdnHCl (final concentrations) and incubated at 25°C; where shown, the reactivation media also contained the proteins whose action on reactivation was studied.
Study characteristics (Table 2): these were nature of applied force, force magnitudes, force reactivations (if studied), total study duration, observation intervals, and type of tooth movement.
Several systems have been used to study HSV-1 reactivation from latency.
