PER2 Circadian Oscillation Sensitizes Esophageal Cancer Cells to Chemotherapy.

Esophageal squamous cell carcinoma (eSCC) accounts for more than 85% cases of esophageal cancer worldwide and the 5-year survival rate associated with metastatic eSCC is poor. This low survival rate is the consequence of a complex mechanism of resistance to therapy and tumor relapse. To effectively reduce the mortality rate of this disease, we need to better understand the molecular mechanisms underlying the development of resistance to therapy and translate that knowledge into novel approaches for cancer treatment.

SCO-spondin oligopeptide inhibits angiogenesis in glioblastoma.

Angiogenesis plays a critical role in glioblastoma growth and progression. We therefore aimed at evaluating the anti-angiogenic properties of an oligopeptide originating from SCO-spondin (NX) on a model of human glioblastoma. To this end, we studied the impact of NX treatment on human brain endothelial cells (HBMECs) alone or co-cultured with glioblastoma cells (U87-MG) on apoptosis, proliferation, migration and release of angiogenic factors.

Uterus human leucocyte antigen expression in the perspective of transplantation.

Aim: To describe class I and II human leucocyte antigen (HLA) expression using different uterine tissues in the perspective of uterus transplantation.

Methods: Human uterine tissues were obtained from 12 women who had undergone hysterectomy for the treatment of benign disease. HLA class I and HLA-antigen D related (DR) expression were assessed via immunochemistry.

New ex-ovo colorectal-cancer models from different SdFFF-sorted tumor-initiating cells.

Despite effective treatments, relapse of colorectal cancer (CRC) is frequent, in part caused by the existence of tumor-initiating cells (TICs). Different subtypes of TICs, quiescent and activated, coexist in tumors, defining the tumor aggressiveness and therapeutic response. These subtypes have been sorted by hyperlayer sedimentation field-flow fractionation (SdFFF) from WiDr and HCT116 cell lines.

Uterus retrieval process from brain dead donors.

Objective: To describe the feasibility of human uterus retrieval after donation after brain death.

Design: Single-center, prospective study.

Setting: University hospital.
