DDR1 and MT1-MMP Expression Levels Are Determinant for Triggering BIK-Mediated Apoptosis by 3D Type I Collagen Matrix in Invasive Basal-Like Breast Carcinoma Cells
In conclusion, and in agreement with the other studies (Ford et al., 2007; Koh et al., 2015; Toy et al., 2015; Takai et al., 2018), our data suggest that during the acquisition of mesenchymal features, the level of full-length DDR1 expression should be considered, in addition to the other markers, as an important biomarker in the prognosis of aggressive breast carcinomas. As summarized in Figure 9, the regulation of cell proliferation and apoptosis by the collagen/DDR1 axis involves a differential activation of DDR1 signaling pathway and thus BIK expression. In the case of the basal-like bre...

Auranofin, an Anti-rheumatic Gold Drug, Aggravates the Radiation-Induced Acute Intestinal Injury in Mice
Conclusion In this study, we found that a non-toxic dose of auranofin significantly aggravated the severity of the radiation-induced intestinal injury. This suggests that auranofin treatment can be an independent factor that influences the risk of intestinal complications after pelvic or abdominal radiotherapy. Ethics Statement All the protocols used in this study were approved by the Institutional Animal Care and Use Committee of the Korean Institute of Radiological and Medical Sciences (IACUC permit number: KIRAMS217-0007). Author Contributions H-JL, JS, and Y-BL designed the experiments. EL and JK conducted the exp...

Resveratrol Promotes Diabetic Wound Healing via SIRT1-FOXO1-c-Myc Signaling Pathway-Mediated Angiogenesis
Conclusion: Our findings indicate that the positive role of RES in diabetic wound healing via its SIRT1-dependent endothelial protection and pro-angiogenic effects involves the inhibition of FOXO1 and the de-repression of c-Myc expression. Introduction Diabetes mellitus is a metabolic disease with an increasing incidence worldwide (Zimmet et al., 2014). The disease often leads to the development of serious complications such as microangiopathy, mainly including retinopathy, nephropathy, neuropathy, and diabetic non-healing skin ulcers (Zheng et al., 2018). Diabetic non-healing skin ulcers such as foot ulcers are ca...

Non-canonical Notch Signaling Regulates Actin Remodeling in Cell Migration by Activating PI3K/AKT/Cdc42 Pathway
In conclusion, our research results indicate that DAPT activates PI3K/AKT/Cdc42 signaling by non-canonical Notch pathway, and the activated Cdc42 promotes the filopodia formation and inhibits lamellipodia assembly, resulting in reduced migration of breast cancer cells. The results imply that non-canonical Notch signaling may play a very important role in the rapid response of cells to the extracellular signals. Author Contributions LG, JD, and LL designed the study and wrote and revised the manuscript. LL and LZ performed most of the experiments and data analysis. SZ, X-YZ, P-XM, Y-DM, Y-YW, YC, S-JT, and Y-JZ assisted i...

Chemical Engineering in the "BIO" world.
Abstract Modern Chemical Engineering was born around the end of the 19th century in Great Britain, Germany, and the USA, the most industrialized countries at that time. Milton C. Whitaker, in 1914, affirmed that the difference between Chemistry and Chemical Engineering lies in the capability of chemical engineers to transfer laboratory findings to the industrial level. Since then, Chemical Engineering underwent huge transformations determining the detachment from the original Chemistry nest. The beginning of the sixties of the 20th century saw the development of a new branch of Chemical Engineering baptized Biomed...
