TOP2 Cancer Research Results

TOP2, Topoisomerase II: Click to Expand ⟱
Source:
Type:
Topoisomerase II (Top2) is a critical nuclear enzyme involved in managing the topology of DNA during essential cellular processes like replication, transcription, recombination, and chromosomal segregation.

- Rapidly dividing cells, including many cancer cells, often show higher Top2 expression.
- In several cancers, such as breast, lung, and hematological malignancies, increased Top2 expression has been correlated with more aggressive tumor subtypes and poorer clinical outcomes.
- The level of Top2 expression can sometimes be used as a prognostic marker, informing predictions about disease progression and potentially patient survival.

MMP1↓, . It can inhibit the expression of MMP-1, MMP-2, and MMP-9 mRNAs along with secretions of TNF-α and IL-1β in THP-1 cells.
MMP2↓,
eff↑, combined administration of metformin, an anti-diabetic drug, and boswellic acid nanoparticles exhibited significant synergism through the inhibition of MiaPaCa-2 pancreatic cancer cell proliferation
BioAv↓, BA as a therapeutic drug is its poor bioavailability
BioAv↑, administration of BSE-018 concomitantly with a high-fat meal led to several-fold increased areas under the plasma concentration-time curves as well as peak concentrations of beta-boswellic acid (betaBA)
Half-Life↓, drug needs to be given orally at the interval of six hours due to its calculated half- life, which was around 6 hrs.
toxicity↓, BSE has been found to be a safe drug without any adverse side reactions, and is well tolerated on oral administration.
Dose↑, Boswellia serrata extract to the maximum amount of 4200 mg/day is not toxic and it is safe to use though it shows poor bioavailability
