AI Article Synopsis

  • Drug resistance poses a major challenge in effective cancer therapy, often leading to disease relapse after initial chemotherapy success.
  • Epithelial-mesenchymal transition (EMT) is a crucial biological process that helps cancer cells become more aggressive and resistant to treatment by changing their characteristics.
  • Natural products show promise as safer cancer treatment options by potentially reversing EMT and addressing drug resistance through their ability to interfere with the underlying molecular mechanisms involved.

Article Abstract

The acquisition of resistance and ultimately disease relapse after initial response to chemotherapy put obstacles in the way of cancer therapy. Epithelial-mesenchymal transition (EMT) is a biologic process that epithelial cells alter to mesenchymal cells and acquire fibroblast-like properties. EMT plays a significant role in cancer metastasis, motility, and survival. Recently, emerging evidence suggested that EMT pathways are very important in making drug-resistant involved in cancer. Natural products are gradually emerging as a valuable source of safe and effective anticancer compounds. Natural products could interfere with the different processes implicated in cancer drug resistance by reversing the EMT process. In this review, we illustrate the molecular mechanisms of EMT in the emergence of cancer metastasis. We then present the role of natural compounds in the suppression of EMT pathways in different cancers to overcome cancer cell drug resistance and improve tumor chemotherapy. HighlightsDrug-resistance is one of the obstacles to cancer treatment.EMT signaling pathways have been correlated to tumor invasion, metastasis, and drug-resistance.Various studies on the relationship between EMT and resistance to chemotherapy agents were reviewed.Different anticancer natural products with EMT inhibitory properties and drug resistance reversal effects were compared.

In the search for novel natural products with hepatoprotective effects against acetaminophen-induced acute liver injury, the marine-derived fungus WHUF0198 was investigated. Seventeen undescribed pyranopyridone alkaloids, aculeapyridones A-Q (-), were isolated by bioactivity-guided fractionation of an extract obtained by coculture of the WHUF0198 with the mangrove-associated fungus sp. DM27.

East Coast Fever (ECF) is one of the leading causes of livestock mortality and reduced productivity across Eastern Africa, and while a live vaccine against it known as the Infection and Treatment Method has existed for three decades now, its adoption by affected communities remains low. This study sought to provide a detailed examination of the dynamics that shape Infection Treatment Method (ITM) vaccine adoption behaviours. The study examined individual, socio-cultural and ecological- level factors influencing ITM adoption using the socio-ecological model.

Tuberculosis (TB) is one of the deadly infectious diseases affecting millions of individuals throughout the world. The main objective of this study is to investigate the impact of media coverage on the transmission dynamics of TB with vaccine and treatment strategy using mathematical model analysis. In the qualitative analysis of the proposed model we proved the existence, uniqueness, positivity, and boundedness of the model solutions, investigated both the disease-free and endemic equilibrium points, computed the basic and effective reproduction numbers using next generation matrix approach, analyzed the stability analysis of the equilibrium points, the backward bifurcation using the Castillo-Chavez and Song theorem and we re-formulated the corresponding optimal control problem and analyzed by applying the Pontryagin's Minimum Principle.

Sulfonamides are prevalent functional groups represented in both natural and pharmaceutical products. The synthesis of sulfonamides is often straightforward when using nucleophilic amines and electrophilic sulfonyl chlorides. When reactivity challenges arise for nontraditional substrates, harsh conditions or new synthetic routes may be required.
