NF-κB can be manipulated by many viral signals. I will go through them one by one eventually. It's possible that I miss some interactions. So please feel free to mention other ones as well and I will add them.
The CtBP -| SIRT4 -| (PI3K -> Akt -> NF‑κB) interaction might be useful for certain kinds of viral mechanisms (
10.1038/cddis.2014.587;
10.3892/mmr.2019.10161). However, if there aren't other helpful interactions with NF-κB signaling, I don't see all pathological cell cycle mechanisms covered. Fortunately, Reishi also suppresses MyD88 and IκB degradation (
10.3892/etm.2013.895). Unrelated to NF-κB, but relevant for the cell cycle, it activates the Caspase pathways as well (
10.1016/S2005-2901(10)60004-0). Am I missing other interactions?
EBV
EBV interacts with NF-κB activation via these pathways:
- dUTPase (lytic) triggers extrinsic TLR2 -> MyD88 -> IRAK -> TRAF6 -> IκB kinase -> NF-κB signaling (10.4049/jimmunol.182.2.851) * †
- Accumulated viral dsRNA and EBERs (predominantly latent) induce RIG-I -> MAVS ->TRAF6 -> IκB kinase -> NF-κB signaling (10.1038/sj.emboj.7601314) ** †
- TRAFs bound to LMP1 (latent and lytic) via TRADD induce NF-κB incuding kinase (NIK) activation and IκB kinase -> NF-κB signaling (10.1111/j.1600-065X.2011.01055.x; 10.1093/emboj/20.20.5678; 10.1016/j.cytogfr.2010.06.002) ** †
- LMP2a and LMP1 (latent and lytic) induce PI3K -> AKT -> mTOR -> NF-κB (10.5501/wjv.v1.i6.154) * ††
- BPLF1 (predominantly late lytic) partially suppresses TRAF6 -> IκB kinase -> NF-κB signaling by deubiquitination (10.1371/journal.ppat.1003960). This suppresses proliferation and immune recognition until reactivation. ¯
Moreover, apoptosis is triggered by viral dsRNA, EBER1 accumulation, and extrinsic Fas activation via PKR -> FADD -> Casp8 -> Bid -> Bax (
10.1021/acs.biochem.0c00088;
10.1016/j.bbamcr.2012.07.003;
10.1099/jgv.0.000313;
10.1126/sciadv.aau9433).
This, however, is inhibited by:
- BHRF1 (lytic) -| Bid -> Bax (10.1073/pnas.0901036106) * †
- BARF1 (lytic) -> Bcl2 -| Bax (10.1007/s12038-015-9502-z) * †
- EBNA3A and EBNA3C (latent) -| Bim -| Bcl2 -| Bax (10.1631/jzus.B1200189) ** ††
Caspases are quite important for a healthy apoptosis. Considering how difficult it might be to normalize their function, and one of your protocols relies on apoptosis, it might be worth reading (
10.1126/sciadv.aau9433).
As an end note, I found this paper that links glycolysis with NADH to NAD+ ratio and CtBP-mediated NF-κB transcription (
10.1038/s41467-017-00707-0). This means, given a high NADH to NAD+ ratio, CtBP can also cause NF-κB-mediated inflammation.

The interactions are concentration-dependent. It's unclear if effective concentrations can be achieved.
