| Brazilian Green Propolis often considered best • Derived from Baccharis dracunulifolia, this type is rich in artepillin C. • It has been widely researched for its anticancer, anti-inflammatory, and antioxidant properties. -Propolis common researched flavonoids :chrysin, pinocembrin, galangin, pinobanksin(Pinocembrin) -most representative phenolic acids were caffeic acid, p-coumaric acid, and ferulic acid, as well as their derivatives, DMCA and caffeic acid prenyl, benzyl, phenylethyl (CAPE), and cinnamyl esters -One of the most studied active compounds of a poplar-type propolis is caffeic acid phenethyl ester (CAPE) -caffeic acid phenethyl ester (CAPE), galangin, chrysin, nemorosone, propolin G, artepillin C, cardanol, pinocembrin, pinobanksin, chicoric acid, and phenolic acids (caffeic acid, ferulic acid, and coumaric acid), as well as luteolin, apigenin, myricetin, naringenin, kaempferol, quercetin, polysaccharides, tannins, terpenes, sterols, and aldehydes -content highly variable based on location and extraction Two main factors of interest: 1. affects interstitual fluild pH 2. high concentration raises ROS (Reactive Oxygen Species), while low concentration may reduce ROS - Artepillin-C (major phenolic compounds found in Brazilian green propolis (BGP)) - caffeic acid major source Propolis is chemically diverse (300+ compounds reported) and composition depends on botanical/geographic source. Antibacterial activity is documented in classic literature (often stronger against Gram+). CAPE from propolis has reported preferential tumor cytotoxicity in early landmark work (often cited in antimicrobial paper references) Do not combine with 2DG Pathways: -Propolis compounds (e.g., artepillin C, caffeic acid phenethyl ester [CAPE]) can trigger apoptosis (programmed cell death) in cancer cells. -Propolis has been shown to inhibit NF‑κB activation. -Propolis extracts can cause cell cycle arrest at specific checkpoints (e.g., G0/G1 or G2/M phases). -Enhance the body’s antitumor immune responses, for example by activating natural killer (NK) cells and modulating cytokine profiles. -Note half-life no standard, high variablity of content. BioAv poor water solubility, and low oral bioavailability. Pathways: - high concentration may induce ROS production, while low concentrations mya low it. This may apply to both normal and cancer cells. Normal Cells Example.

| Vimentin, a major constituent of the intermediate filament family of proteins, is ubiquitously expressed in normal mesenchymal cells and is known to maintain cellular integrity and provide resistance against stress. Vimentin is overexpressed in various epithelial cancers, including prostate cancer, gastrointestinal tumors, tumors of the central nervous system, breast cancer, malignant melanoma, and lung cancer. Vimentin’s overexpression in cancer correlates well with accelerated tumor growth, invasion, and poor prognosis; however, the role of vimentin in cancer progression remains obscure. In many epithelial-derived tumors (carcinomas), elevated Vimentin expression is often observed in cancer cells that have undergone EMT. This upregulation is characteristic of a shift toward a mesenchymal state, which is associated with reduced cell–cell adhesion and increased motility. Vimentin expression is also noted in the tumor stroma, reflecting the presence and activation of mesenchymal cells such as cancer-associated fibroblasts (CAFs). This dual expression can contribute to the remodeling of the tumor microenvironment. The degree of Vimentin expression may vary depending on the tumor type, grade, and stage. More aggressive and advanced tumors tend to show higher levels of Vimentin expression. High Vimentin expression has been correlated with poor clinical outcomes in several cancers, including breast, colorectal, prostate, and lung cancers. Elevated Vimentin levels are typically associated with higher tumor grade, increased invasiveness, enhanced metastatic potential, and a greater risk of recurrence. As a component of the EMT signature, high Vimentin expression can serve as an indicator of a more aggressive tumor phenotype and is often associated with reduced overall survival. - vimentin up-regulation is often used as a marker of EMT in cancer |
