Aim:
The study aimed to assess the anticancer effects of leaves of the male and female plant and seeds Carica papaya L. extract and the active compound benzyl isothiocyanate on oral squamous cell carcinoma (OSCC) cell line.
Materials And Methods:
Extracts of CO2 strain C. papaya L. seeds were prepared using water, ethanol, and ethanol:water by maceration, and benzyl isothiocyanate was quantified. Alkaloid fractions of leaves of male and female plants of C. papaya L. were prepared and quantified. The anticancer effects of the test substances on the SCC-25 cell line were assessed by MTT, apoptosis assay, cell cycle analysis, and determination of mitochondrial membrane potential.
Results:
The ethanol:water extract of C. papaya L. (seeds) demonstrated the highest quantity of benzyl isothiocyanate. Male plant leaves demonstrated greater alkaloid content. The leaves of the male plant exhibited apoptosis induction and S-phase arrest, whereas the leaves of the female plant and seeds of C. papaya L. demonstrated G2M-phase arrest and apoptosis induction.
Conclusion:
C. papaya L. and benzyl isothiocyanate demonstrated anticancer effects. There was a difference in the anticancer effects of leaves of male and female plants of C. papaya L.
Clinical Significance:
The anticancer effects of papaya leaves and seeds could be further explored to develop an adjunct therapy for oral cancer to improve prognosis and reduce recurrence rates.

However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...
