BCR: Targeting Collagen XIII Protein Is Expected to Successfully Treat Breast Cancer Metastasis

Recently, researchers from the University of Kentucky found that targeting a protein called collagen XIII  may effectively inhibit the metastasis of breast cancer. And the article related was published on Breast Cancer Research.   Breast cancer begins in epithelial cells, cells that are arranged in organs and tissues of the body. In general, most of the epithelial cells die when detached from the extracellular matrix. This type of programmed cell…

Cancer Res: Cancer Stem Cells May Use Normal Genes to “Do Evil”

CDK1 is a normal protein that drives cells through the replication cycle, while MHC class 1 molecule is also a normal molecule that exhibits a small amount of protein on the cell surface for examination by the immune system; Recently, scientists from the University of Colorado Cancer Center found that a group of cancer cells labeled with MHC class 1 molecule and high levels of CDK1 are extremely unusual. In…

Nature: “Reconstruct” T cells into the Brain and Attack “Escape” Cancer Cells

For glioblastoma, immunotherapy faces a particular challenge—the blood-brain barrier blocks T cells from entering the brain to prevent brain inflammation that can be life-threatening. This “protective measure” is beneficial under normal conditions, but it prevents T cells from reaching the glioblastoma, leaving immunotherapy useless.   On September 5th, Nature published an article entitled “A homing system targets therapeutic T cells to brain cancer”, which reveals a new solution from a…

PCGF5 Is Required for Neural Differentiation of Embryonic Stem Cells

Researcher Yao Hongjie from the Guangzhou Institute of Biomedicine and Health, Chinese Academy of Sciences published a research report entitled “PCGF5 is required for neural differentiation of embryonic stem cells” on Nature Communications. This work reveals the molecular mechanism by which polycomb PCGF5 regulates the differentiation of embryonic stem cells into neural precursor cells.   Epigenetic modification plays an important role in maintaining stem cell characteristics and cell fate transformation….

New Mechanism by Which Cancer Cells Inhibit Anti-tumor Immune Responses Revealed

Cancer cells are not just a group of cells that are out of control; for their own survival, they actively participate in the struggle with the immune system. Being able to evade detection by the immune system is a feature of cancer. In a new study, researchers from the University of Pennsylvania found that cancer cells release biological “unmanned aerial vehicles” – small vesicles called exosomes that circulate in the…

Alzheimer’s Disease and Insulin—Is There Any Connection?

Johnson & Johnson recently announced that the company has stopped a clinical trial of a new Alzheimer’s disease drug due to certain safety issues. This is another failed clinical trial following the announcement of several large clinical trials that have no effect in treating Alzheimer’s disease. More and more failure cases tell us that we need to stop and think about how we could find the cause of Alzheimer’s disease….

Nat Med: Key Factors Determining the Anticancer Effect of Immunological Checkpoint Therapy

Stimulatory dendritic cells (SDCs) play a key role in stimulating cytotoxic T lymphocytes and promoting immune responses against cancer. Studying the mechanisms that regulate the abundance of SDCs in the tumor microenvironment (TME) will provide new therapeutic strategies.     Rencently, researchers from the University of California, San Francisco, studied the abundance in human melanoma and the influencing factors of SDC, and found it was associated with intratumoral expression of…

Immunity: Why Can’t HIV Be Cured? Scientists Find the Key Mechanism!

Due to the rapid development of antiretroviral therapy (ART), HIV patients can live longer than before. But even if it is a very effective long-term ART, the HIV virus remains stubbornly incurable, so patients need medication for life. Scientists have been convinced that this is because the HIV virus has created a stubborn virus-infected cell nest that allows HIV to survive indefinitely. A recent study done by researchers at Brigham…

PNAS: A Key Switch in Biological Clocks Found

Multipoint phosphorylation of the PERIOD 2 (PER2) protein is a critical step in determining the mammalian clock cycle. Previous studies have suggested that the phosphorylation of PER2 by casein kinase 1 (CK1) requires the initiation of an undiscovered protein kinase. CK1 is an essential circulatory protein that is highly conserved from algae to humans. These phosphorylation processes stabilize the PER2 and delay its degradation to extend the circadian clock cycle….
