Summary: The specific depletion of microglia in the early stage of ischemic stroke can significantly reduce the infarct volume and improve motor ability. Depleting microglia also leads to a decrease in degenerating neurons and inducible nitric oxide synthase positive (iNOS(+)) cells. Moreover, the depletion of microglia results in an increase in anti-inflammatory factors and a decrease in pro-inflammatory factors 3 days after stroke. These findings suggest that modulation of the inflammatory response through the elimination of microglia may be a promising therapeutic approach for the treatment of cerebral ischemia.

Summary: In this study, the positive effect of Sox9 deletion on acute liver injury repair was observed. Sox9 deletion resulted in the suppression of SHP expression, leading to less cell death and more cell proliferation. Additionally, Sox9 was found to directly bind to the SHP promoter and regulate SHP transcription, improving mitochondrial function and ameliorating acute liver injury.

Summary: In this study, a multistage chemodynamic therapy (CDT) specific to tumor cells is proposed, which can efficiently deplete the high glutathione (GSH) content in tumor cells. By consuming reserved GSH and inhibiting GSH synthesis in cancer cells, the CDT achieves potent GSH exhaustion. The glycolysis inhibitor used in this study not only increases the sensitivity of tumor cells to CDT, but also stimulates a protective mode in normal cells. This tumor-specific CDT utilizes the responsiveness of the glycolysis inhibitor and nanocarrier to the tumor microenvironment.

Summary: The roles of NLRP3, AIM2 inflammasomes, and Gasdermin D (GsdmD) in lung cancer progression are unclear. Using a metastatic LLC cell model, this study found that GsdmD knockout mice exhibited significantly fewer lung cancer foci, decreased metastasis, and increased median survival rate. GsdmD and IL-1 beta were detected in lung tumor tissue, indicating inflammasome activity. Conditioned media from wild-type macrophages enhanced migration and growth of LLC cells, while GsdmD(-/-) macrophages did not. Bone marrow transplantations confirmed the myeloid-specific role of GsdmD in lung cancer metastasis.

Summary: This study established a novel mouse model with a DTR under the control of the Ly6G promoter for specific depletion of neutrophils. The model allows complete neutrophil depletion through DT treatment at intervals, enabling research on the roles of neutrophils in the immune system and tumor progression.

Summary: The study on PCSK9 knockout mice reveals that female mice shed soluble ectodomain of LDLR massively, while male mice rely on high surface LDLR for replenishment. This shedding process is cholesterol-dependent and influenced by hormone levels in female mice.

Summary: In this study, we successfully invalidated the ALDH1L2 gene using CRISPR-cas9 technique and found that the knockout of this gene rendered U251 glioblastoma cells methionine-independent in terms of cancer stem cell growth. We also observed higher levels of reactive oxygen radicals (ROS) and reduced total cellular NADPH in the knockout cells. The slower growth of the knockout tumor sphere may be related to its partial differentiation.

Summary: This study evaluated the mechanism of action of isolated pentapeptides from Isochrysis zhanjiangensis on inflammation and tumor angiogenesis. The results showed that these pentapeptides effectively inhibited cell invasion and migration by downregulating the expression of specific proteins, and achieved anti-inflammatory and anti-tumor angiogenesis effects through the regulation of multiple signaling pathways.

Summary: This study evaluated the mechanism of action of pentapeptides derived from Isochrysis zhanjiangensis on inflammation and tumor angiogenesis. The results showed that these pentapeptides effectively inhibited the invasion and migration of endothelial cells and tumor cells, as well as regulated specific signaling pathways and molecular expression.

Summary: This review introduces how the signaling axis between SIRT1 and HMGB1 regulates inflammation-related responses and tumor occurrence. It explores upstream regulators and potential treatment methods for inflammatory responses. Additionally, it suggests that SIRT1 and HMGB1 may be potential targets for treating inflammation.

Summary: This study found that myofibroblasts in the kidneys of ADPKD patients can promote the proliferation of cyst epithelial cells, cyst growth, and fibrosis. Targeting this cell type could be a novel therapeutic strategy for treating ADPKD.

Summary: TNF-alpha is a crucial mediator in the development of psoriasis. Inhibition of TNF can be an effective treatment, but it may also cause adverse effects. Studies have shown that the TNFR2 pathway plays a key role in psoriatic inflammation. Therefore, targeting the TNFR2 pathway could be a potential new approach for treating psoriatic diseases.

Summary: This study assessed the reducing effect of bergamottin on the development of liver damage in cafeteria diet fed mice. The results demonstrated that cafeteria diet caused metabolic changes, endoplasmic reticulum stress, oxidative stress, and inflammation in serum and liver tissue. However, bergamottin showed antioxidant, anti-endoplasmic reticulum stress, and anti-inflammatory effects in cafeteria-induced liver damage.

Summary: Glioblastoma (GBM) is an incurable and highly malignant brain tumor. This study investigated the effects of Medicarpin (MED) on GBM cell apoptosis and the potential molecular mechanisms. The results showed that MED inhibited cell proliferation and migration, induced apoptosis, and suppressed GBM tumorigenesis. It was also found that MED upregulated pro-apoptotic proteins and improved the survival rate of tumor-bearing mice.
