A Supported Nickel Catalyst Stabilized by a Surface Digging Effect for Efficient Methane Oxidation.

A surface digging effect of supported Ni NPs on an amorphous N-doped carbon is described, during which the surface-loaded Ni NPs would etch and sink into the underneath carbon support to prevent sintering. This process is driven by the strong coordination interaction between the surface Ni atoms and N-rich defects. In the aim of activation of C-H bonds for methane oxidation, those sinking Ni NPs could be further transformed into thermodynamically stable and active metal-defect sites within the as-generated surface holes by simply elevating the temperature.

The communication between tumor-derived elements and stroma in the metastatic niche has a critical role in facilitating cancer metastasis. Yet, the mechanisms tumor cells use to control metastatic niche formation are not fully understood. Here we report that in the lung metastatic niche, high-metastatic hepatocellular carcinoma (HCC) cells exhibit a greater capacity to convert normal fibroblasts to cancer-associated fibroblasts (CAFs) than low-metastatic HCC cells.

Noncoding RNAs in liver cancer stem cells: The big impact of little things.

The high rate of recurrence and heterogeneity make hepatocellular carcinoma (HCC) as one of the most prevalent malignancy worldwide. Cancer stem cells (CSCs), also known as tumor-initiating cells, are responsible for cancer initiation, metastasis, drug resistance and relapse, accounting for the heterogeneous and hierarchical organizations of HCC. Therefore, CSCs are novel targets for more efficient liver cancer therapies.
