Squamous cell carcinoma (SCC) is the most common oral cavity carcinoma. Conventional therapeutic modalities for oral malignancy include surgery, radiotherapy and chemotherapy alone or in combinations. The major obstacle of using current anticancer drugs is; first the non-specific tissue distribution, as these drugs are unable to distinguish between normal and cancer cells. Quercetin is a bioactive flavonoid having strong antioxidant properties. It is naturally present in a wide variety of fruits and vegetables. Among all the nanomaterials, polymeric nanoparticles are of significant interest for drug delivery applications due to many unique features of nanoparticle polymers. Polymeric nanocarriers have been fabricated from natural and synthetic polymers. Poly ethylene glycol-poly lactide-co-glycolic acid (PEG-PLGA) amphiphilic copolymer is an emergent system because it can be easily synthesized and possesses a lot of good qualities. Several previous in vitro and in vivo studies have evaluated the cytotoxic effects of quercetin and have revealed that it decreases cell viability and increases cell apoptotic rate in OSCC. However, the anti-cancer property of quercetin in tongue squamous cell carcinoma (TSCC) has not been studied yet. This is the first study to investigate the anticancer effects of (Quercetin) either free or encapsulated by PLGA-PEG NPs in tongue squamous cell carcinoma (TSCC) cell line.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Cytotoxicity/Cell viability.

    MTT assay for cellular viability:

    The cytotoxic impacts of the tested drugs and Nano QUT-encapsulation will be measured by MTT. The (HNO-97) cells will be cultured in 96-well plates at a density of 5 × 103 cells/well. All drugs with their described concentrations will be added to the media over tongue SCC cell lines. After a day of incubation, the dissolved MTT in PBS will be added to each well at a final concentration of 5 mg/ml, and the samples will be incubated at 37 °C for 4h. Water-insoluble dark blue formazan crystals that will be formed during MTT cleavage in actively metabolizing cells will then be dissolved in dimethyl sulfoxide (DMSO). Absorbance will be measured at A455 nm, using an ELISA microplate reader

    Measured: within 1 week after cell line propagation

  2. Apoptosis.

    Annexin V and propidium iodide (PI) stains will be used in the determination of apoptosis after treatment with the free, nano counterpart of QUT and free Dox post 24h of their incubation over the HNO-97 cell line. The apoptotic analysis will be dedicated to differentiating between early and late apoptotic cells, as well as necrotic cells. The apoptosis of the treated and untreated HNO-97 line with the proposed free, nano counterpart of Nano-QUT and Dox will be analyzed by flow cytometer apparatus

    Measured: within 1 week after cell line propagation

Secondary outcomes (3)
  1. Gene expression of (BCL-2) .

    Following treatment with the proposed free DOX, free and Nano-QUT formulations for 24 h, the cells are harvested, lysed and tested with RT-PCR using specific primers to estimate the fold change of the apoptotic signals (BCL-2 and Bax) and survival pathway (Expression of PI3K gene). GAPDH will be used as a housekeeping gene to normalize the level of target gene expression.

    Measured: within 1 week after cell line propagation

  2. Gene expression of ( Bax gene)

    Following treatment with the proposed free DOX, free and Nano-QUT formulations for 24 h, the cells are harvested, lysed and tested with RT-PCR using specific primers to estimate the fold change of the apoptotic Bax gene

    Measured: within 1 week after cell line propagation

  3. survival pathway (Expression of pi3k gene)

    Following treatment with the proposed free DOX, free and Nano-QUT formulations for 24 h, the cells are harvested, lysed and tested with RT-PCR using specific primers to estimate the fold change of survival pathway (Expression of pi3k gene)

    Measured: within 1 week after cell line propagation

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 13 Jul 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Egypt. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Hana'a Algadi, P.h.D (01116360252, hanaahezamalgadi@yahoo.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Cytotoxicity/Cell viability. (time frame: within 1 week after cell line propagation). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Jul 2022.
