Drug resistance is an obstacle to chemotherapy in tumor patients. Recent studies have shown that the high stemness of cancer cells may be induced by chemotherapeutic drugs, which is correlated with drug resistance. In the present study, we investigated the effects of bufalin on the stemness of colorectal cancer. We found that cisplatin could induce high stemness through the tumorsphere formation assay in vitro and in vivo in the colorectal cancer cell lines HCT116 and LoVo. In addition, cisplatin-treated tumorsphere cells showed drug-resistant properties. These results suggested that acquired drug resistance induced by cisplatin in colorectal cancer cells occurred via high stemness. On assessing the effects of bufalin, a traditional Chinese medicine monomer, we found that it could reverse the high stemness and drug resistance induced by cisplatin in colorectal cancer. These findings suggest that bufalin plays an adjuvant role in colorectal cancer chemotherapy and may help reverse acquired drug resistance. These findings may aid in the development of new therapeutic strategies.

PGE2-JNK signaling axis non-canonically promotes Gli activation by protecting Gli2 from ubiquitin-proteasomal degradation

Jun Yang, Juan Wang, Yuan Liu, Yu Zhang, Wenjing Huang, Yu Zou, Yanyan Qiu, Weiyang Cai, Jing Gao, Hu Zhou, Yingli Wu, Weijun Liu, Qingqing Ding, Yanjie Zhang, Pei-hao Yin, Wenfu Tan

Summary: The study reveals that colorectal cancer cells exploit PGE2 to promote Hh activity in a non-canonical manner, leading to Gli-dependent proliferation. Mechanistically, PGE2 activates JNK, enabling Gli2 to evade degradation by phosphorylating Gli2 at Thr1546.

Photodynamic therapy synergizes with PD-L1 checkpoint blockade for immunotherapy of CRC by multifunctional nanoparticles

Zeting Yuan, Guohua Fan, Honglei Wu, Chaolian Liu, Yueping Zhan, Yanyan Qiu, Chenting Shou, Feng Gao, Jun Zhang, Peihao Yin, Ke Xu

Summary: Recent studies show that photodynamic therapy (PDT) can enhance the therapeutic effects of PD-L1 blockade in colorectal cancer (CRC) by inducing tumor cell death, stimulating immune response, and preventing tumor recurrence through upregulation of PD-L1 expression via the hypoxia-inducible factor 1a (HIF-1a) signaling pathway. This combination therapy using multifunctional nanoparticles loaded with photosensitized mTHPC (mTHPC@VeC/T-RGD NPs) shows promise in improving the response rate of anti-PD-L1 checkpoint blockade immunotherapies in CRC.

Summary: Extracellular vesicles (EVs) have emerged as a promising cell-free strategy in the treatment of bone-related diseases. However, challenges such as uncertain distribution, unfavorable therapeutic efficiency, and low yields hinder their clinical application. Internal and external engineering of EVs can address these issues and improve their bone-targeting capacity.

Bufalin exacerbates Photodynamic therapy of colorectal cancer by targeting SRC-3/HIF-1? pathway

Zeting Yuan, Chaolian Liu, Yuji Sun, Yue Li, Honglei Wu, Shuli Ma, Jing Shang, Yueping Zhan, Peihao Yin, Feng Gao

Summary: This study designed iRGD-modified nanoparticles to co-deliver mTHPC and BU, aiming to enhance the efficacy of photodynamic therapy (PDT) in colorectal cancer (CRC). The nanoparticles passively accumulated in tumor cells, with mTHPC inducing apoptosis and death under laser irradiation, while the sustained release of BU inhibited hypoxia and angiogenesis by targeting the SRC-3/HIF-1α pathway.

Bufalin reverses cancer-associated fibroblast-mediated colorectal cancer metastasis by inhibiting the STAT3 signaling pathway

Haijing Wang, Jinbao Chen, Sen Li, Jiahua Yang, Donghao Tang, Wentao Wu, Kun Yu, Yijun Cao, Ke Xu, Peihao Yin, Yi Chen, Wei Li

Summary: Currently, recurrence and metastasis remain significant factors leading to poor prognosis in colorectal cancer (CRC) patients. Cancer-associated fibroblasts (CAFs) play a crucial role in promoting tumorigenesis and development. Bufalin, the main active monomer of the clinical drug cinobufacini, has exhibited anti-tumor activity in various cancers. However, limited research has investigated the effect of bufalin in inhibiting metastasis from the perspective of the tumor microenvironment. This study isolated CAFs from freshly resected CRC patient specimens and observed their effect on CRC cell invasion. The study also explored the physiological activity of CRC mediated by CAFs and the inhibitory effect of bufalin on CAF-mediated CRC invasion and metastasis through the STAT3 pathway.

α-hederin overcomes hypoxia-mediated drug resistance in colorectal cancer by inhibiting the AKT/Bcl2 pathway

Jinbao Chen, Jian Xu, Jiahua Yang, Yueping Zhan, Sen Li, Linlin Jia, Wentao Wu, Xianke Si, Die Zhang, Kun Yu, Peihao Yin, Yijun Cao, Wanli Deng, Ke Xu, Wei Li

Summary: Chemoresistance is a significant challenge for patients with colorectal cancer (CRC), and hypoxia is associated with poor prognosis and therapeutic resistance in cancer patients. Alpha-hederin has shown antitumour effects and can inhibit hypoxia-mediated drug resistance in CRC, but the underlying mechanism is still unclear. This study reveals that alpha-hederin inhibits drug resistance in hypoxic CRC cells by reducing AKT phosphorylation and Bcl2 expression, promoting apoptosis. These findings suggest that alpha-hederin may be a promising adjuvant for reversing drug resistance in CRC.

c-Jun phosphorylated by JNK is required for protecting Gli2 from proteasomal-ubiquitin degradation by PGE2-JNK signaling axis

Jun Yang, Juan Wang, Yu Zhang, Wenjing Huang, Shaoqing Zhang, Peihao Yin, Wenfu Tan

Summary: In colorectal cancer, PGE2-JNK can activate the Hh signaling pathway non-canonically. This study demonstrates that c-Jun prevents Gli2 protein from degradation by protease through phosphorylation by PGE2. Suppression of c-Jun decreases Gli2 expression and ubiquitination, and restricts PGE2-induced Hh activity and colorectal cancer cell proliferation.

Bufalin-loaded vitamin E succinate-grafted chitosan oligosaccharide/RGD-conjugated TPGS mixed micelles inhibit intraperitoneal metastasis of ovarian cancer

Lan Xu, Shuli Ma, Bozhen Fan, Zeting Yuan, Peihao Yin

Summary: In this study, vitamin E succinate (VES)-grafted chitosan oligosaccharide (CSO)/arginine-glycine-aspartic acid peptide (RGD)-conjugated d-alpha-tocopheryl polyethylene glycol 1000 succinate (TPGS) mixed micelles (VeC/T-RGD MMs) were used to deliver bufalin (BU) to ovarian cancer cells to inhibit intraperitoneal metastasis. The BU-loaded VeC/T-RGD MMs (BU@MMs) effectively inhibited cell proliferation, induced apoptosis, and reduced the migration and invasion of ovarian cancer cells. The BU@MMs also showed better biocompatibility and biosafety for in vivo applications.
