Cancers, Vol. 12, Pages 881: Extracellular Vesicles Enriched with Moonlighting Metalloproteinase Are Highly Transmissive, Pro-Tumorigenic, and Trans-Activates Cellular Communication Network Factor (CCN2/CTGF): CRISPR against Cancer Cancers doi: 10.3390/cancers12040881 Authors: Yuka Okusha Takanori Eguchi Manh T. Tran Chiharu Sogawa Kaya Yoshida Mami Itagaki Eman A. Taha Kisho Ono Eriko Aoyama Hirohiko Okamura Ken-ichi Kozaki Stuart K. Calderwood Masaharu Takigawa Kuniaki Okamoto Matrix metalloproteinase 3 (MMP3) plays multiple roles in extracellular proteolysis as well as intracellular transcription, prompting a new definition of moonlighting metalloproteinase (MMP), according to a definition of protein moonlighting (or gene sharing), a phenomenon by which a protein can perform more than one function. Indeed, connective tissue growth factor (CTGF, aka cellular communication network factor 2 (CCN2)) is transcriptionally induced as well as cleaved by MMP3. Moreover, several members of the MMP family have been found within tumor-derived extracellular vesicles (EVs). We here investigated the roles of MMP3-rich EVs in tumor progression, molecular transmission, and gene regulation. EVs derived from a rapidly metastatic cancer cell line (LuM1) were enriched in MMP3 and a C-terminal half fragment of CCN2/CTGF. MMP3-rich, LuM1-derived EVs were disseminated to multiple organs through body fluid and were pro-tumorigenic in an allograft mouse model, whic...

zu Geeta Upadhyay Elevated gene expression of Lymphocyte antigen 6K (LY6K) in cancer cells is associated with poor survival outcomes in multiple different cancer types including cervical, breast, ovarian, lung, and head and neck cancer. Since inhibition of LY6K expression inhibits cancer cell growth, we set out to explore whether pharmacological inhibition of LY6K could produce the same effect. We screened small molecule libraries for direct binding to recombinant LY6K protein in a surface plasmon resonance assay. We found that NSC243928 directly binds to the full-length and mature forms of LY6K and inhibits growth o...

Abstract Photodynamic therapy is the combination of the initial application of a photosensitive chemical on the skin and then using typically a blue filter light of varying spectrums. This treatment protocol has been more useful and functional than other chemical peels and lasers for a variety of conditions. There has been efficacy in antiviral treatments, such as herpetic lesions; malignant cancers of the head and neck; and lung, bladder, and skin cancers. It has been tested for prostate cancers, cervical cancer, colorectal cancer, lung cancer, breast cancer, esophageal cancer, stomach cancer, pancreatic cancer, ...

This study investigated the prevalence and the distribution of FGFR aberrations in Chinese cancer patients.MethodsWe screened genomic profiling results of plasma or tissue samples from 10,582 patients spanning 16 cancer types: lung, breast, gastric, hepatobiliary, pancreatic, soft tissue sarcoma, esophageal, ovarian, colorectal, head and neck, renal, endometrial, osteogenic sarcoma, cervical, melanoma and lymphoma.ResultsOf the 10,582 patients screened, we observed 745 patients with FGFR aberrations, revealing an overall prevalence of 7.03%. Approximately, 3.78% harbored FGFR amplification, 2.73% had other mutations and 0....

In this study, the lung adenocarcinoma patients and granuloma patients were treated as positive samples and negative samples, respectively. We used weighted accuracy to evaluate the RIPPER prediction performance, i.e., the average of the accuracies of positive samples and negative samples. Results The Discriminative MicroRNAs Between Lung Adenocarcinoma and Granuloma Patients in Whole Plasma, EV, and EV-Free Plasma The miRNA expression profiles of lung adenocarcinoma and granuloma patients in whole plasma, EV and EV-free plasma were analyzed separately. In whole plasma, the top 10 discriminative miRNAs were hsa-miR-223-...

Discussion Suppressor of cytokine signaling 1 is an essential molecule for maintaining immune homeostasis and subverting inflammation. Disorders arising from excess inflammation or SOCS1 deficiency can be potentially treated with SOCS1 mimetics (Ahmed et al., 2015). While SOCS1 has promising potential in many disorders, it should be noted that new targets and actions of SOCS1 are still being discovered and not all the effects of this protein are beneficial in autoimmune diseases and cancer. For instance, SOCS1 degrades IRS1 and IRS2, required for insulin signaling, via the SOCS Box domain, thus, limiting its potential in ...
