Mucin1 (MUC1), a heterodimeric oncoprotein, containing tandem repeat structures with a high proportion of threonine, is aberrantly overexpressed in many human cancers including pancreatic cancer. Since the overall survival rate of pancreatic cancer patients has remained low for several decades, novel therapeutic approaches are highly needed. Intestinal mucin has been known to be affected by dietary threonine supply since de novo synthesis of mucin proteins is sensitive to luminal threonine concentration. However, it is unknown whether biosynthesis of MUC1 is regulated by threonine in human cancers...

Sunitinib resistance is, nowadays, the major challenge for advanced renal cell carcinoma patients. Illuminating the potential mechanisms and exploring effective strategies to overcome sunitinib resistance are highly desired. We constructed a reliable gene signature which may function as biomarkers for prediction of sunitinib sensitivity and clinical prognosis. The gene expression profiles were obtained from The Cancer Genome Atlas database. By performing GEO2R analysis, numerous differentially expressed genes (DEGs) were found to be associated with sunitinib resistance...

Targeted delivery of DNA nanoparticles is a promising approach in cancer therapy. Using aptamers, target specific delivery of DNA nanoparticles can be achieved. Further, aptamers can indirectly improve drug encapsulation efficiency of DNA nanoparticles for drugs intercalated within nucleic acid base pairs. Using DNA blocks, a micellar hybrid nanoparticle was prepared for the targeted co-delivery of doxorubicin and a pro-apoptotic peptide, KLA to tumor cells. Results demonstrated that anti-MUC1 aptamer could specifically deliver the synthesized DNA micelle into MCF-7 cells by improving its cellular uptake...

Amino acids carrying 4-methylbenzyl (MBn) and 4-methoxybenzyl (MPM)-protected sialic acid were synthesized and used for the 9-fluorenylmethoxycarbonyl (Fmoc) solid-phase synthesis of a glycopeptide. The alpha-sialyl linkage of the MBn-protected unit was partially cleaved under the final deprotection by trifluoroacetic acid (TFA). In addition, the removal of several MBn groups were incomplete. On the other hand, the MPM-protected unit gave the desired glycopeptide without decomposition of the -sialyl linkage...

To enhance efficacy of chemotherapy and achieve real-time imaging of cancer cells, it is crucial to develop nanocarriers with targeted drug delivery capacity and fluorescence property for cancer theranostics. Herein, a dual-targeting DNA tetrahedron nanocarrier (MUC1-Td-AS1411) was constructed for breast cancer cell imaging and targeted drug delivery. This nanocarrier consisted of three components: (i) DNA tetrahedron core for multivalent conjugation of function ligands and loading doxorubicin (Dox); (ii) activatable MUC1 aptamer probe (MUC1-probe), formed by the hybridization of MUC1 aptamer sequence with fluorophore extended from one vertex and complementary sequence with quencher, for targeting and imaging MUC1 protein on cytomembrane; (iii) AS1411 aptamer, which was hybridized to the overhang on three vertexes via prolonged sequence, for binding to nucleolin...

The existence of cancer stem cells (CSCs) is the main reason for failure of cancer treatment caused by drug resistance. Therefore, eradicating cancers by targeting CSCs remains a significant challenge. In the present study, because of the important role of BMI-1 proto-oncogene, polycomb ring finger (BMI-1) and C-terminal Mucin1 (MUC1-C) in tumor growth and maintenance of CSCs, we aimed to confirm that microRNA miR-128, as an inhibitor of BMI-1 and MUC1-C, could effectively suppress paclitaxel (PTX)-resistant lung cancer stem cells...

Background: Mucin1 (MUC1) is a highly glycosylated transmembrane protein that has gained attention because of its overexpression in various cancers. However, MUC1-targeted therapeutic antibodies have not yet been approved for cancer therapy. MUC1 is cleaved to two subunits, MUC1-N and MCU1-C. MUC1-N is released from the cell surface, making MUC1-C a more reasonable target for cancer therapy. Therefore, we produced a monoclonal antibody (anti-hMUC1) specific to the extracellular region of MUC1-C and evaluated its effects in vitro and in vivo...

Mucin 1 (MUC1), a cell surface glycoprotein, is expressed mainly in the endometrial luminal epithelium (LE) and glandular epithelium (GE) of the endometrium in many mammalian species including mice, rats, pigs, sheep, horses and humans during various stages of a menstrual or oestrous cycle, where it plays an important role in embryo implantation and placentation. However, the expression and function of MUC1 in uterine tissues during early pregnancy in sheep after artificially-induced oestrous is not known. Therefore, we investigated the expression and function of MUC1 in the early pregnant and non-pregnant uterine tissues of sheep with natural oestrous or artificially-induced oestrous on days 10, 12, 14, 16 and 18 of the cycle by in situ hybridization, quantitative real-time polymerase chain reaction, immunohistochemical staining and western blotting methods...

The abnormal hypoglycosylated form of the epithelial mucin MUC1 is over-expressed in chronic inflammation and on human adenocarcinomas, suggesting its potential role in inflammation-driven tumorigenesis. The presence of human MUC1 aggravates colonic inflammation and increases tumor initiation and progression in an in vivo AOM/DSS mouse model of colitis-associated cancer (CAC). High expression levels of pro-inflammatory cytokines, including TNF-α and IL-6, were found in MUC1+ inflamed colon tissues. Exogenous TNF-α promoted the transcriptional activity of MUC1 as well as over-expression of its hypoglycosylated form in intestinal epithelial cells (IECs)...

Therapeutic cancer vaccines aim to treat pre-existing cancer by boosting the patient's own immune system, which is an attractive strategy for cancer treatment. The cancer vaccines have mainly been designed to elicit antitumor T-cell immune responses that recognize and eradicate cancer. The advantages of cancer immunotherapy with cancer vaccines include a) high specificity of tumor antigen, b) minimal vaccine-related adverse events, and c) long-lasting immunity boosted by cancer vaccine which is important to control tumor relapse...

An intraductal tubulopapillary neoplasm (ITPN) is a very rare pancreatic tumor. Here we report an extremely rare case of an ITPN rupturing and causing acute peritonitis. A 50-year-old woman presented with left flank pain and vomiting. A computed tomography (CT) scan revealed gigantic multilocular cysts in the pancreatic tail and massive fluid collection in the abdominal cavity. The serum, urine, and abdominal fluid amylase levels were highly elevated, so she was conservatively treated with intraperitoneal drainage and antibiotics for a diagnosis of ruptured pancreatic cysts...

STUDY QUESTION: Is transplantation of cryopreserved ovarian tissue from patients with borderline ovarian tumors (BOTs) a safe procedure? SUMMARY ANSWER: BOT cells were found in frozen-thawed and xenografted ovarian tissue in 1 of 11 BOT patients. WHAT IS KNOWN ALREADY: The risk of reintroducing malignant cells upon ovarian tissue transplantation has been subject of debate for many years. Reimplantation of cryopreserved ovarian tissue from leukemia patients is unsafe, while results from studies of cryopreserved ovarian tissue from other forms of cancer, such as Hodgkin's lymphoma, are reassuring...

Cellular glycosylation processes are vital to cell functioning. In malignant cells, they are profoundly altered. We used time-course gene expression data from the NCI-60 cancer cell lines treated with 11 antitumor agents to analyze expression changes of genes involved in glycosylation pathways, genes encoding glycosylation targets or regulators, and members of cancer pathways affected by glycosylation. We also identified glycosylation genes for which pretreatment expression levels or changes after treatment were correlated with drug sensitivity...

Triple negative breast cancer (TNBC), which constitutes 10%-20% of all breast cancers, is associated with aggressive progression, a high rate of metastasis, and poor prognosis. The treatment of patients with TNBC remains a great clinical challenge. Preclinical reports support the combination immunotherapy of cancer vaccines and immune checkpoint blockades in non-immunogenic tumors. In this study, we constructed nanoparticles (NPs) to deliver an mRNA vaccine encoding tumor antigen MUC1 to dendritic cells (DCs) in lymph nodes to activate and expand tumor-specific T cells...

Solid tumors involving glandular organs express mucin glycoprotein which is eventually shed into the circulation. As aresult these proteins can easily be measured in the serum and be used as potential tumor markers. The most commonly used tumor markers for breast cancer are CA 27-29 and CA 15-3, which both measure the glycoprotein product of the mucin-1 (MUC1) gene. CA 27-29 has been approved by the US Food and Drug Administration for monitoring disease activity in breast cancer patients. Most oncology clinical practice guidelines do not recommend the use of tumor markers for routine surveillance of early stage disease but recognize their utility in the metastatic setting...
