  • Patent number: 12366993
    Abstract: A memory system includes a memory device including at least one storage region; and a controller coupled to the memory device. The controller separates write data input from an external device from metadata associated with data stored in the memory device. Based on an operation state of the at least one storage region, the controller stores the write data into a buffer storing data to be transferred to the at least one storage region in the memory device. The controller stores the metadata into the buffer regardless of the operation state of the at least one storage region. The controller transfers the write data or the metadata stored in the buffer to the memory device for storing the write data or the metadata in the memory device.

  • Publication number: 20250113808
    Abstract: The present invention relates to a brain-metastatic lung cancer cell line and a use of Noggin as a marker for brain metastasis of lung cancer. In the present invention, a brain metastatic lung cancer cell line with optimized characteristics for brain metastasis was established by repeatedly transplanting the lung cancer cell line through the carotid artery. In addition, in the brain metastatic lung cancer cell line, the expressions of Noggin protein and its mRNA are reduced, confirming that the motility and invasiveness of cells are reduced and adhesion increased. Therefore, the Noggin protein or its gene is expected to be useful as a biomarker for diagnosis of brain metastasis of lung cancer and its target therapy.
