Chrysin / ROS Cancer Research Results

CHr, Chrysin: Click to Expand ⟱
Features:
Chrysin is found in passion flower and honey. It is a flavonoid.
-To reach plasma levels that might more closely match the concentrations used in in vitro studies (typically micromolar), considerably high doses or advanced delivery mechanisms would be necessary.
Chrysin is widely summarized as modulating PI3K/Akt and MAPK pathways in cancer.

Chrysin — Chrysin is a naturally occurring flavone-class flavonoid found in honey, propolis, passionflower, and several plants. Its oncology relevance is mainly preclinical: it shows multi-pathway anticancer activity in cell and animal models, but native oral chrysin has very poor systemic bioavailability and no established approved oncology use.

Primary mechanisms (ranked):

  1. Suppression of PI3K/AKT survival signaling with downstream reduction in proliferation and survival programs.
  2. Induction of mitochondrial apoptosis through Bax/Bcl-2 shift, mitochondrial membrane potential loss, cytochrome c release, and caspase activation.
  3. Context-dependent ROS stress amplification in cancer cells, often linked to mitochondrial injury, ER stress, and apoptosis.
  4. ER stress / unfolded-protein-response activation leading to autophagy or stress-to-death coupling.
  5. Suppression of inflammatory, invasive, angiogenic, and metastatic signaling including NF-κB, MMPs, EMT, VEGF, and HIF-1α axes.
  6. Secondary antioxidant / NRF2-linked cytoprotection in some normal-cell or injury models, which is context-dependent and not necessarily anticancer-selective.

Bioavailability / PK relevance: Native oral chrysin has very poor systemic exposure because of low aqueous solubility, extensive intestinal/hepatic glucuronidation and sulfation, and efflux; human oral bioavailability has been reported as extremely low, often summarized as below 1%. Formulation strategies such as nanoparticles, lipid systems, micelles, cyclodextrins, or structural analogues are commonly proposed for systemic translation.

In-vitro vs systemic exposure relevance: Most anticancer studies use micromolar in-vitro concentrations that are unlikely to be reached in plasma after ordinary oral chrysin. Local intestinal exposure may be more plausible than systemic tumor exposure, but systemic anticancer claims should be treated as formulation-dependent.
LipoMicel may increase bioavailability

Clinical evidence status: Preclinical. Evidence is strong enough for mechanistic oncology interest in cell and animal models, including combination/sensitization studies, but there is no mature clinical oncology evidence establishing therapeutic benefit.

ROS, Reactive Oxygen Species: Click to Expand ⟱
Source: HalifaxProj (inhibit)
Type:
Reactive oxygen species (ROS) are highly reactive molecules that contain oxygen and can lead to oxidative stress in cells. They play a dual role in cancer biology, acting as both promoters and suppressors of cancer.
ROS can cause oxidative damage to DNA, leading to mutations that may contribute to cancer initiation and progression. So normally you want to inhibit ROS to prevent cell mutations.
However excessive ROS can induce apoptosis (programmed cell death) in cancer cells, potentially limiting tumor growth. Chemotherapy typically raises ROS.
-mitochondria is the main source of reactive oxygen species (ROS) (and the ETC is heavily related)

"Reactive oxygen species (ROS) are two electron reduction products of oxygen, including superoxide anion, hydrogen peroxide, hydroxyl radical, lipid peroxides, protein peroxides and peroxides formed in nucleic acids 1. They are maintained in a dynamic balance by a series of reduction-oxidation (redox) reactions in biological systems and act as signaling molecules to drive cellular regulatory pathways."
"During different stages of cancer formation, abnormal ROS levels play paradoxical roles in cell growth and death 8. A physiological concentration of ROS that maintained in equilibrium is necessary for normal cell survival. Ectopic ROS accumulation promotes cell proliferation and consequently induces malignant transformation of normal cells by initiating pathological conversion of physiological signaling networks. Excessive ROS levels lead to cell death by damaging cellular components, including proteins, lipid bilayers, and chromosomes. Therefore, both scavenging abnormally elevated ROS to prevent early neoplasia and facilitating ROS production to specifically kill cancer cells are promising anticancer therapeutic strategies, in spite of their contradictoriness and complexity."
"ROS are the collection of derivatives of molecular oxygen that occur in biology, which can be categorized into two types, free radicals and non-radical species. The non-radical species are hydrogen peroxide (H 2O 2 ), organic hydroperoxides (ROOH), singlet molecular oxygen ( 1 O 2 ), electronically excited carbonyl, ozone (O3 ), hypochlorous acid (HOCl, and hypobromous acid HOBr). Free radical species are super-oxide anion radical (O 2•−), hydroxyl radical (•OH), peroxyl radical (ROO•) and alkoxyl radical (RO•) [130]. Any imbalance of ROS can lead to adverse effects. H2 O 2 and O 2 •− are the main redox signalling agents. The cellular concentration of H2 O 2 is about 10−8 M, which is almost a thousand times more than that of O2 •−".
"Radicals are molecules with an odd number of electrons in the outer shell [393,394]. A pair of radicals can be formed by breaking a chemical bond or electron transfer between two molecules."

Recent investigations have documented that polyphenols with good antioxidant activity may exhibit pro-oxidant activity in the presence of copper ions, which can induce apoptosis in various cancer cell lines but not in normal cells. "We have shown that such cell growth inhibition by polyphenols in cancer cells is reversed by copper-specific sequestering agent neocuproine to a significant extent whereas iron and zinc chelators are relatively ineffective, thus confirming the role of endogenous copper in the cytotoxic action of polyphenols against cancer cells. Therefore, this mechanism of mobilization of endogenous copper." > Ions could be one of the important mechanisms for the cytotoxic action of plant polyphenols against cancer cells and is possibly a common mechanism for all plant polyphenols. In fact, similar results obtained with four different polyphenolic compounds in this study, namely apigenin, luteolin, EGCG, and resveratrol, strengthen this idea.
Interestingly, the normal breast epithelial MCF10A cells have earlier been shown to possess no detectable copper as opposed to breast cancer cells [24], which may explain their resistance to polyphenols apigenin- and luteolin-induced growth inhibition as observed here (Fig. 1). We have earlier proposed [25] that this preferential cytotoxicity of plant polyphenols toward cancer cells is explained by the observation made several years earlier, which showed that copper levels in cancer cells are significantly elevated in various malignancies. Thus, because of higher intracellular copper levels in cancer cells, it may be predicted that the cytotoxic concentrations of polyphenols required would be lower in these cells as compared to normal cells."

Majority of ROS are produced as a by-product of oxidative phosphorylation, high levels of ROS are detected in almost all cancers.
-It is well established that during ER stress, cytosolic calcium released from the ER is taken up by the mitochondrion to stimulate ROS overgeneration and the release of cytochrome c, both of which lead to apoptosis.
