Continuing therapy is typically the preferred choice for the majority of physicians because maintaining undetectable HBV DNA levels does not represent serum immunological response.
All patients on antiviral therapy have maintained undetectable HBV DNA levels and were followed at three to four monthly intervals.
Within 10 months of antiviral therapy all treated subjects showed undetectable HBV DNA, and they maintained undetectable HBV DNA levels throughout with the HBV DNA assayed at six monthly intervals.
Partial reversal of the mesenchymal-like phenotype in D609-treated MDA-MB-231 cells was further supported by a strong decrease of N-cadherin (by 74% ± 4% at 24 hours, Student t test P = 0.01, and 75% ± 9% at 120 hours, P ≤ 0.005), whereas E-cadherin maintained practically undetectable levels throughout cell incubation with D609.
Older patients have a higher probability to maintain undetectable HIV-RNA viral load (adherence effect?).
Multiple mechanisms have been proposed to explain why HIV controllers maintain low to undetectable levels of viral replication in the absence of therapy.
Many of the secreted MMPs, including MMPs 1, 3, 9, 10, 11, and 13, are not expressed in normal, healthy resting tissues, and with some exceptions, their production and activity are maintained at nearly undetectable levels [ 12, 13].
Importantly, our findings reveal that the post-transcriptional control of let-60 mRNA by PUF-8 and the protein-level of control of LET-60 RAS activity by the RasGAP GAP-3 constitute a redundant mechanism to maintain the MPK-1 activity at undetectable levels in the mitotic, meiotic-entry and the early pachytene regions.
All cells had undetectable levels of mycoplasma when thawed, and were maintained in culture for up to 3 months.
As ESCs were maintained in 2iLIF in these experiments to repress Erk1/2 to undetectable levels by western blot (Fig. 2E), the difference could reflect genetic differences.
