5 %) and Hispanic (21.4 %) adults were diagnosed with distant disease compared to White adults (19.4 %). Differences in sex-specific survival were minimal, with only differences between Hispanic men (62.0 % [60.5 %-63.4 %]) and women (65.9 % [64.4 %-67.3 %]). TAK-981 SUMO inhibitor SES differences were largest between the lowest quintile 63.0 % (62.3 %-65.2 %) and the highest quintile 67.8 % (66.8 %-68.8 %). SES-, stage-, and race/ethnicity-stratified analysis demonstrated improving trends for White adults with localized and regional disease, and Hispanic adults with regional disease.
Colon cancer survival in California is lower for Black and Hispanic adults than for White adults in all three categories stage, sex, and SES, suggesting the need for improved health policy for Hispanic and Black adults.

Breast cancer is the most common female cancer worldwide. Large hypoxic area is one of the features of tumor microenvironment. Highly activated hypoxia-induced pathways positively correlate with poor clinical response to chemo- and radiotherapy and high mortality in breast cancer patients.
We explore the effect of sanguinarine on hypoxia-induced activation of Ephrin type-B receptor 4 (EphB4) and hypoxia inducible factor-1α (HIF-1α) pathways in breast cancer.
Hypoxia-induced expression of a receptor tyrosine kinase EphB4 was observed in hypoxic breast cancer cell models. Sanguinarine, a natural alkaloid, could effectively combat hypoxia-induced EphB4 and HIF-1α expression. Sanguinarine inhibited the activation of downstream protein signal transducer and activator of transcription-3 (STAT3), thereby blocking hypoxia-induced HIF-1α/STAT3 interaction and downregulating the mRNA levels of their target genes. Mechanically, sanguinarine attenuated HIF-1α protein levels via inhibition of MAPK/ERK pathways and promotion of HIF-1α proteasome degradation. Sanguinarine inhibited STAT3 activation through targeting its upstream EphB4 and accelerating STAT3 dephosphorylation. Correspondingly, xenograft models confirmed that sanguinarine treatment disrupted hypoxia-induced pathways and inhibited tumor growth in vivo.
Our results may bring insights to the hypoxia-induced pathways in breast cancers, and suggest sanguinarine as a promising candidate for EphB4 and HIF-1α-targeted inhibition.

Radix Astragali (RA) consists of the dried root of Astragalus membranaceus Bunge and is one of the most frequently used dietetic Chinese herbs to treat inflammation and neurodegenerative disease among other conditions. Radix Astragali preparata (RAP) is a medicinal form of RA. RA and RAP have been used as anti-aging agent, however, the mechanisms underlying their effects are still unclear.
Considering the wide application of RA and RAP in clinical practice, it is necessary to identify the better product between the two and elucidate the molecular mechanism responsible for their anti-aging effects.
In this study, network pharmacology integrated with molecular biology techniques were employed to explore the possible mechanism of RA and RAP against aging.
Aging animal models were constructed by exposure to D-galactose (D-gal), and the anti-aging effect of RA and RAP were determined based on behavior tests and histomorphological observation. Network pharmacology was performed to construct the "compound-target-pathway" network. Gene and protein expression of possible targets were validated and analyzed using qRT-PCR and Western blotting.
Treatment by RA and RAP could alleviate the symptoms of aging such as a decrease in body weight and organ indices, behavioral impairment, increased oxidative stress, weaken histopathological evaluation. The effect of RAP was more pronounced than that of RA in preventing aging process in a mouse model. The anti-aging effect of RA and RAP is associated with the balance of oxidative stress and activation of PI3K/Akt signaling pathway.
Using an integrated strategy of network pharmacology and molecular biology we attempted to elucidate the mechanisms of action of RA and RAP.

Myocardial infarction (MI) is a lethal manifestation of cardiovascular diseases. Oxidative stress, inflammation, and subsequent cell death are known to play crucial roles in the pathogenesis of MI. Despite tremendous developments in interventional cardiology, there is need for novel drugs for the prevention and treatment of MI. For the development of novel drugs, usage of natural products has gained attention as a therapeutic approach for ischemic myocardial injury. Among many popular plant-derived compounds, Nootkatone (NKT), a natural bioactive sesquiterpene, abundantly found in grapefruit, has attracted attention for its plausible health benefits and pharmacological properties.
The present study investigated the cardioprotective effects of NKT in rats against MI induced by isoproterenol (ISO), a synthetic catecholamine and β-adrenergic agonist that produces MI in a physiologically relevant manner.
MI was induced in male Wistar albino rats by subcutaneous injection of ISO (85 mg/kg body weight) on 9
.
The present study concludes the cardioprotective effects and underlying mechanisms of NKT against ISO-induced MI in rats, and suggests that NKT or plants containing NKT could be an alternative to cardioprotective agents in ischemic heart diseases.
Matrine (Mat), a bitter tastes compounds of derived from leguminosae such as Sophora flavescens and S. subprostrata, commonly used to improve obesity and diabetes.
Our study to demonstrate bitter substances can stimulate the Bitter taste receptors (TAS2Rs) or Calcium-sensing receptor (CaSR) to stimulate the secretion of GLP-1 to promote blood glucose regulation.
The diabetic mice and intestinal secretory cell model were established to evaluate the Mat on glucose metabolism, intestinal insulin secretion and GLP-1 secretion related substances. To clarify the mechanism of Mat in regulating GLP-1 secretion by immunofluorescence, calcium labeling, siRNA, and molecular docking.
The results showed that Mat could significantly improve glucose metabolism and increased insulin and GLP-1 secretion in diabetic mice and increased trisphosphate inositol (IP3) levels by affecting the expression of phospholipase C β2 (PLCβ2) and promote an increase in intracellular Ca2
levels in STC-1 cells to subsequently stimulate the secretion of GLP-1.
