In this study, a mechanical isolation technique was adopted to isolate MEFs and the efficiency of this technique was compared with enzymatic digestion method. The suspended MEFs were prepared either by mechanical method or 0.

Inhibition of USP14 induces ER stress-mediated autophagy without apoptosis in lung cancer cell line A549.

Non-small cell lung cancer is the most common type of lung cancer, accounting for more than 80% of this tumor.

A glimpse into molecular mechanisms of embryonic stem cells pluripotency: Current status and future perspective.

Embryonic stem cells have potential differentiation ability into a large variety of cell lineages and proved to be an effective therapeutic modality. However, prolonged in vitro and ex-vivo expansions impair embryonic stem cells multipotentiality, and thereby limit their clinical application. In the past few years, research collected attempts to explore new insights into the molecular mechanisms participate in the stemness capacity of embryonic stem cells.

Current progress in hepatic tissue regeneration by tissue engineering.

Liver, as a vital organ, is responsible for a wide range of biological functions to maintain homeostasis and any type of damages to hepatic tissue contributes to disease progression and death. Viral infection, trauma, carcinoma, alcohol misuse and inborn errors of metabolism are common causes of liver diseases are a severe known reason for leading to end-stage liver disease or liver failure. In either way, liver transplantation is the only treatment option which is, however, hampered by the increasing scarcity of organ donor.

Ischemic acute kidney injury and klotho in renal transplantation.

Post-transplant ischemic acute kidney injury (AKI), secondary to ischemia reperfusion injury (IRI), is a major problem influencing on the short and long term graft and patient survival. Many molecular and cellular modifications are observed during IRI, for example, tissue damage result production of reactive oxygen species (ROS), cytokines, chemokines, and leukocytes recruitment which are activated by NF-κB (nuclear factor kappa B) signaling pathway. Therefore, inhibiting these processes can significantly protect renal parenchyma from tissue damage.
