Esophageal squamous cell carcinoma (ESCC) is an aggressive malignancy that is often resistant to therapy. Nowadays, chemotherapy is still one of the main methods for the treatment of ESCC. However, the multidrug resistance (MDR)-mediated chemotherapy resistance is one of the leading causes of death. Exploring agents able to reverse MDR, which thereby increase the sensitivity with clinical first-line chemotherapy drugs, could significantly improve cancer treatment. Cepharanthine hydrochloride (CEH) has the ability to reverse the MDR in ESCC and the mechanism involved have not been reported...

Esophageal squamous cell carcinoma (ESCC) is one of the deadliest cancers, and it requires novel treatment approaches and effective drugs. In the present study, we found that treatment with plumbagin, a natural compound, reduced proliferation and survival of the KYSE150 and KYSE450 ESCC cell lines in a dose-dependent manner in vitro. The drug also effectively inhibited the viability of primary ESCC cells from fresh biopsy specimens. Furthermore, plumbagin-induced mitotic arrest and massive apoptosis in ESCC cells...

Checkpoint inhibitors, such as anti-PD-1 (Programmed death-1), are transforming cancer treatment for inoperable or advanced disease. As the incidence of obesity-associated malignancies, including esophageal adenocarcinoma (EAC) continue to increase and treatment with checkpoint inhibitors are being FDA approved for a broader range of cancers, it is important to assess how anti-PD-1 treatment might exacerbate pre-existing inflammatory processes at other sites. Outside the EAC tumor, the omentum and liver were found to be enriched with substantial populations of PD-1 expressing T cells...

The epithelial-mesenchymal transition (EMT) transcription factor SNAIL is associated with distant metastasis and poor prognosis of esophageal squamous cell carcinoma (ESCC) patients. The proteolysis of SNAIL is mediated by the ubiquitin-proteasome system. Several E3 ligases have been characterized to promote SNAIL ubiquitination and degradation. However, the reverse process - deubiquitination of SNAIL remains largely unknown. In this study, we performed a mass spectrometry to examine the interaction between SNAIL and deubiquitinating enzyme(s)...

For decades, proteases have been associated with cancer progression due to the ability of some members of this large group of enzymes to degrade tumor cell surroundings, thereby facilitating cancer invasion and dissemination. However, the generation of mouse models deficient in proteases has revealed the existence of a great variety of functions among proteolytic enzymes in cancer biology, including important tumor-suppressive roles. Therefore, in this chapter, we describe methods to chemically induce different types of cancer (lung adenocarcinoma, hepatocellular carcinoma, oral and esophageal carcinoma, colorectal carcinoma, skin cancer, and fibrosarcoma) in genetically modified mouse models to efficiently evaluate the specific pro- or antitumoral function of proteases in cancer...
