Tissue Engineering Scaffolds Loaded With a Variety of Plant Extracts: Novel Model in Breast Cancer Therapy

Despite recent improvements in detecting and managing breast cancer (BC), it continues to be a major worldwide health concern that annually affects millions of people. Exploring the anti-BC potentials of natural compounds has received a lot of scientific attention due to their multi-target mode of action and good safety profiles because of these unmet needs. Drugs made from herbs are secure and have a lot fewer negative effects than those made from synthetic materials. Early stage patients benefit from breast-conserving surgery, but the risk of local recurrence remains, necessitating implanted scaffolds. These scaffolds provide residual cancer cell killing and tailored drug delivery. This review looks at plant extract-infused tissue engineering scaffolds, which provide a novel approach to treating BC. By offering patient individualized, safer treatments, these scaffolds could completely change how BC is treated.

A Review on the Nutraceutical Anti-Metastatic Importance of Annona Muricata Crude Extract (AMCE) and its Coping Mechanism Against Breast Cancer

Background:

Annona Muricata is used as a folkloric herbal medicine as it has anticancer, antiproliferative and anti-tumorigenic properties. The extracts from various parts of the plant are considered therapeutic due to Annonaceous Acetogenin compounds which are an absolute boon to the versatility of the plant, paving the mechanistic pathways for its therapeutic potential.

Method:

Google Scholar and PubMed databases were reviewed with the main focus on availing information on Annona muricata and its anticancer effect on breast cancer.

Results and Discussion:

- An array of clinical investigations on the dosage of extracts on cell lines, animal models, and human trials provide confirmatory insights of A. muricata as a preventive and therapeutic measure for cancer. The extract when administered at different dosages shows a high cytotoxic effect on the cancer cells, mostly accounting for an IC50 of less than 1000µg/mL which is of significance.

Conclusion -:

Although high efficacy has been conclusive, assurance of the safety prior to commercialization is of significance. Investigations are required to define the origin and magnitude of side effects along with long-term safety for the enhancement of efficacy and optimum utilization of potential chemo-preventive properties of the plant for the curation of a nutraceutical intervention for cancer that surpasses the traditional medicine.

Antitumor Potential of Annona muricata Linn. An Edible and Medicinal Plant in Mexico: In Vitro, In Vivo, and Toxicological Studies

Annona muricata (Am) is a plant used in traditional Mexican medicine to treat cancer. In this study, ethanol extracts of Am collected in Acapulco and Tecpan from Guerrero state were evaluated orally on Balb/c mice inoculated with 4T1 cells, for cytotoxic activity (CA) on 4T1 cells, in brine shrimp lethality assay (BSLA), and for acute oral toxicity in mice. In addition, ethanol extracts were subjected to high-performance liquid chromatography (HPLC) with diode array detection. Results showed that the extracts collected in December in Acapulco (AcDe) and Tecpan (TeDe) exhibited the most significant antitumor and cytotoxic activity. In the BSLA, the most important effect was observed in the extracts from Acapulco and Tecpan collected in June (AcJu) and August (TeAg), respectively. The samples from Acapulco (AcJu, and AcAg) and Tecpan (TeJu and TeAg) showed the highest toxicity. The analysis of the extracts, AcDe and TeDe, by HPLC revealed that flavonoids, rutin, narcissin, and nicotinflorin were the major components. These findings suggest that extracts from Am collected in Acapulco and Tecpan in the month of December may be an important source to obtain flavonoid glycosides with anticancer potential specifically against breast cancer. This also supports the use of Am to treat cancer in Mexican traditional medicine.
