Cancer-associated fibroblasts (CAFs) play a crucial role in cancer progression and even initiation. However, the origins of CAFs in various cancer types remain controversial, and one of the important hypothesized origins is through epithelial-mesenchymal transition (EMT) from cancer cells. In this study, we investigated whether the HEp-2 laryngeal cancer cells are able to generate CAFs via EMT ...

Studies on urban extreme precipitation and its influencing factors are significant for prevention reduction of meteorological disasters; however, few studies focus hourly (HEP) events due to the limitation observation. By using summer data in Beijing from 1980 2020, spatial distribution temporal variation HEP as well local environmental investigated. It is found that both amount frequency affec...

Abstract In many countries, thunderstorms are the main contributor to hourly extreme precipitation (HEP). Prior studies have shown that number of decreased steadily in whole country China; however, HEP has increased significantly several areas over past half-century. The role changes occurrence remains largely unknown China. this study, for first time, we used continuous 32-yr records and thund...

In this paper we consider pulsating strings in warped AdS 6 × S 4 background, which is a vacuum solution of massive type IIA super-string. The case of rotating strings in this background was considered in hep-th/0402202 and it was found that the results significantly differs from those considered in AdS 5 ×S 5. Motivated by this results we study pulsating strings in the warped spherical part of...

PURPOSE This study was designed to evaluate the levels of Interleukin-6 (IL6) and Hepcidin prohormone (Hep) in the serum and aqueous humor of patients with primary open-angle glaucoma (POAG), as well as those with senile cataract as a control group. METHODS Levels of IL6 and Hep were measured by enzyme-linked immunosorbent assay (ELISA) methods in serum and aqueous humor aspirates taken from ...

Chemoresistance is a major obstacle in chemotherapy of laryngeal carcinoma. Recently, studies indicate that cancer stem cells are responsible for chemotherapy failure. In addition, microRNAs play important roles in tumor initiation, development and multidrug resistance. In the present study, we found that the expression of microRNA-125a was decreased in laryngeal carcinoma tissues and Hep-2 lar...

Streptococcus pyogenes adheres to human epithelial cells in vitro and in vivo. To identify adhesins, cell wall components were extracted from S. pyogenes M6 with alkali or by treatment with mutanolysin and lysozyme. HEp-2 cells were incubated with extracts of S. pyogenes M6 and then analyzed by Western blot (immunoblot) assays, using antibodies to S. pyogenes. Only one streptococcal component (...

Glucose transporter-1 (GLUT-1) and PI3K/Akt are known to be closely involved in resistance to chemotherapy. Co-targeted therapy reducing GLUT-1 expression and PI3K/Akt pathway activity may overcome the chemoresistance of human cancers. Apigenin may inhibit the expression of GLUT-1 and the PI3K/Akt pathway. We hypothesized that over-expression of GLUT-1 and p-Akt was associated with the resistan...

I report on two papers, hep-ph/9806279 and hep-ph/9807336, where complementary strategies are proposed for the determination of the chargino/neutralino sector parameters, M1,M2, μ and tanβ, from the knowledge of some physical observables. This determination and the occurrence of possible ambiguities are studied as far as possible analytically within the context of the unconstrained MSSM, assumi...
