In the canonical Wnt/-catenin signaling pathway, -catenin features being a coactivator from the transcription aspect T cell aspect/lymphocyte enhancer aspect (TCF/LEF) and promotes the transcription of Wnt focus on genes, that are responsible for managing cell fate in a variety of diseases, including cancers (Cui et?al., 2018). -Catenin is normally overexpressed and constitutively turned on in individual cancer tumor and plays a part in cancer tumor initiation, progression, metastasis, drug resistance, and immune evasion (Pai et?al., 2017; Cui et?al., 2018). Targeting -catenin signaling has been proposed as a promising strategy to develop effective anticancer brokers (Qin et?al., 2018b; Cheng et?al., 2019). Recent improvements in understanding the protein structures of -catenin alone and complexed with its coactivators have promoted the design and development of specific small-molecule inhibitors (Krishnamurthy and Kurzrock, 2018; Zhang X. et?al., 2020). These -catenin signaling inhibitors have shown anticancer efficacy in preclinical settings, and some of them have entered clinical trials, such as PRI-724 (Krishnamurthy and Kurzrock, 2018). However, none of these -catenin inhibitors has been approved for clinical use yet. It is still urgently needed to identify more specific, safe, and effective -catenin inhibitors for malignancy treatment. Natural products and their derivatives represent a major source for anticancer drug discovery (Qian et?al., 2013; Qin et?al., 2017). Over the past few decades, about 33.5% of FDA-approved anticancer drug entities are recognized from natural products or their derivatives (Newman and Cragg, 2020). Many natural products have been found to exert their anticancer activity by inhibiting oncoproteins (e.g. -catenin and MDM2) and/or reactivating tumor suppressors (e.g. p53 and Puma) (Li et?al., 2013; Qin et?al., 2018a; Wang W. et?al., 2018; Wang et?al., MAC13772 2020; Zhang J. et?al., 2020). It has also been reported that natural products can enhance the chemosensitivity of malignancy cells by suppressing the functions of drug resistance-related proteins (Feng et?al., 2017; Dong et?al., 2020; Yuan et?al., 2020). Recent studies have recognized several natural products with potent inhibitory effects around the -catenin signaling and shown promising anticancer efficacy and and anticancer activities, and underlying molecular mechanisms. Moreover, we summarize known natural-product-based -catenin-targeting strategies and propose new strategies that may be used to identify more specific and effective -catenin inhibitors for malignancy prevention and therapy. Wnt/-Catenin Signaling Pathway The Wnt/-catenin pathway ( Physique 1 ) plays an important role in malignancy development and progression by promoting the cytoplasmic accumulation and nuclear translocation of -catenin and activating the transcription of genes related to malignancy cell proliferation, cell cycle progression, anti-apoptosis, migration, invasion, and drug resistance (Krishnamurthy and Kurzrock, 2018). In the absence of Wnt activation, -catenin is usually phosphorylated by the destruction complex ( Physique 1A ), which includes Axin, adenomatous polyposis coli (APC), glycogen synthase kinase 3 (GSK3), and casein kinase 1 (CK1) (Stamos and Weis, 2013). When -catenin is usually recruited to the destruction complex, CK1 in the beginning phosphorylates -catenin at Ser45 and GSK3 further promotes -catenin phosphorylation at Ser33, Ser37, and Thr41 (Amit et?al., 2002; Liu et?al., 2002; Wu and He, 2006). Subsequently, the phosphorylated -catenin is usually acknowledged and ubiquitinated by the E3 ligase protein -transducin repeat-containing protein (-TrCP), which consequently results in the proteasomal degradation of -catenin (Aberle et?al., 1997; Orford et?al., 1997; Stamos and Weis, 2013). Open in a separate window Physique 1 The Wnt/-catenin signaling pathway.

The E3 ligase -TrCP further induces -catenin ubiquitination and proteasomal degradation. E-cadherin and -catenin also form complex to enhance cell adhesion. MAC13772 (B) In the Wnt-on state, Wnt proteins bind to Frizzled receptor and LRP co-receptor and recruit and activate Dishevelled, which further inhibits the activity of GSK3 and releases -catenin from your destruction complex.

Natural products and their derivatives represent a major source for anticancer drug discovery (Qian et?al., 2013; Qin et?al., 2017).

Many natural basic products have been discovered to exert their anticancer activity by inhibiting oncoproteins (e.g. -catenin and MDM2) and/or reactivating tumor suppressors (e.g. p53 and Puma) (Li et?al., 2013; Qin et?al., 2018a; Wang W. et?al., 2018; Wang et?al., 2020; Zhang J. et?al., 2020). It has additionally been reported that natural basic products can boost the chemosensitivity of tumor cells by suppressing the features of medication resistance-related protein (Feng et?al., 2017; Dong et?al., 2020; Yuan et?al., 2020).
