Abstract
Background
The volatile fraction of frankincense (Boswellia sacra) oleogum was extracted, formulated in nanoemulsion and tested against lung cancer A549 cell line. First, the gum was hydro-distilled to isolate the volatile fraction (essential oil), which was analyzed via gas chromatography to identify its major volatile constituents. Then, the oil was formulated in two water-based nanoemulsions which differ from one another in the presence of propylene glycol (PG), which is used in the formulation step as a co-surfactant. The pure essential oil as well as its major volatile compound (α-pinene), its two nanoemulsions and a reference drug (Doxorubicin) were evaluated against lung cancer A549 cell lines and WI-38 normal lung cells. The evaluation included cytotoxicity (MTT and IC50), apoptosis (flow cytometric analysis) in addition to genetic assessments for some intrinsic and extrinsic genes relevant to apoptosis and survival pathways.
Results
Chromatographic analysis of frankincense essential oil revealed that α-pinene is the major volatile compound which constituent about 60% of that oil. Emulsification of the oil using the low energy technique gave nanoemulsions having major intense particles population (85–90%) with z-average diameter below 20.0 nm. Frankincense oil nanoemulsion fabricated with (PG) showed the best cytotoxic activity toward lung cancer A549 cell compared to PG-free nanoemulsion, α-pinene and the reference drug doxorubicin, along different incubation periods. Flow cytometric analysis also indicated that PG-containing nanoemulsion can induce cancer cells toward apoptosis better than the other formula and the pure oils. The same nanoemulsion was found to upregulate the pro-apoptotic genes [DR5, FAAD, Caspase 8 (Cas8), p53, and Bax] and downregulate the anti-apoptotic and reoccurrence genes (Bcl-2, NF-kB, and STAT-3). Most importantly, the PG-containing nanoemulsion had the least cytotoxic effect on the normal WI-38 lung cells.
Conclusions
These results point out to the potentials of frankincense essential oil (rich in α-pinene) and its PG-nanoemulsion as a promising adjuvant from plant-source to potentiate the activity of the systematic anti-lung cancer drugs.

Abstract
Nanoformulation-based combinational drug delivery systems are well known to overcome drug resistance in cancer management. Among them, nanoemulsions are well-known and thermodynamically stable drug delivery systems suitable for carrying hydrophobic drugs and phytoconstituents to tackle drug-resistant cancers. In the present study, we have investigated the effect of paclitaxel in combination with erucin (natural isothiocyanate isolated from the seeds of Eruca sativa) loaded in the frankincense oil-based nanoemulsion formulation. The choice of frankincense oil for the current study was based on reported research investigations stating its magnificient therapeutic potential against breast cancer. Optimized nanoemulsion of paclitaxel (PTX) and erucin (ER) combination (EPNE) provided sustained release and exhibited enhanced cytotoxicity towards human epithelial breast cancer cells (T-47D) as compared to individual ER and PTX. EPNE was further assessed for its antitumor activity in the 7,12-dimethylbenz(a)anthracene (DMBA)-induced breast cancer mice model. EPNE significantly decreased the levels of hepatic and renal parameters along with oxidative stress in breast cancer mice. Furthermore, EPNE also showed decreased levels of inflammatory cytokines TNF-α, IL-6. Histopathological examinations revealed restoration of the tumorous breast to normal tissues in EPNE-treated breast cancer mice. Therefore, EPNE can act as a viable lead and therapeutic option for drug-resistant breast cancer.
