Summary: Using a mouse model of FLT3-ITD AML, researchers found that FLT3-ITD AML LSC were enriched within the ST-HSC population and had increased expression of CXCR4. Deletion of CXCL12 from the microenvironment enhanced targeting of AML cells by Flt3-TKI plus chemotherapy treatment, including enhanced LSC targeting. Inhibition of p38 signaling reduced the maintenance of Flt3-ITD AML LSC and enhanced their sensitivity to treatment.

Summary: Membrane-anchored proteins and their mimics, such as PNAs, show selective partitioning into lipid raft or non-raft domains based on their lipophilic anchors. In this study, anchor-matched PNA was found to be excluded from the lipid raft domains of giant unilamellar vesicles when hybridized with complementary flavin-labeled DNA. The distribution of PNA was not only dependent on the lipophilic anchor, but also on the structure of the hybridized DNA or PNA pair.

Summary: The study investigated the cooperative role of CXCR4/CXCL12 axis and IL-1Ra in the metastasis of colorectal cancer cells. It was found that IL-1 alpha and rIL-1 alpha promoted CXCL12 expression, while IL-1Ra inhibited this effect. Additionally, CXCL12 enhanced migration and proliferation of endothelial cells, and IL-1Ra inhibited migration, proliferation, and angiogenesis of colorectal cancer cells.

Summary: This study evaluated the effect of Flavokawain A (FKA) on pulmonary fibrosis and found that FKA alleviated the development of fibrosis and improved lung function by inhibiting TGF-beta 1/Smad signaling and myofibroblast activation. Additionally, FKA reduced extracellular matrix production and collagen deposition by blocking CXCL12/CXCR4 signaling and inhibiting CXCL12 dimerization. FKA shows promise as a therapeutic agent for pulmonary fibrosis.

Summary: Environmental factors and lack of therapeutic targets contribute to the development and poor prognosis of TNBC. This study identified CXCR4 as a potential therapeutic target in TNBC, and found that ZGA can downregulate CXCR4 expression and inhibit TNBC cell migration and invasion. Furthermore, ZGA was effective in inhibiting tumor growth and metastasis in a TNBC mouse model. Overall, this research highlights the importance of targeting CXCR4 in the treatment of TNBC.

Summary: Lymphocytes stimulated by CXCL12 can affect surrounding cells' chemotactic response, promoting chemotaxis of CXCR4-deficient cells but inhibiting CCR7 ligand-dependent directionality. This suggests that paracrine factors can guide surrounding cells to migrate towards CXCL12 by regulating responsiveness to chemokines.

Summary: Studying the phase separation of ER membranes is crucial for understanding the fundamental biology of ER. However, NIR ratiometric imaging of ER phase behaviors has not been explored in living cells and diverse tissues. In this study, we developed a polarity-responsive NIR fluorescent probe to visualize the phase behavior in ER membranes and revealed different phase behaviors in different tissues.

Summary: This study aimed to develop a murine model of steroid-resistant asthma and investigate the role of group 2 innate lymphoid cells (ILC2s) in producing IL-5, a type-2 cytokine. The results showed that in steroid-resistant asthma, ILC2s produced larger amounts of IL-5 in response to IL-33/TSLP, and the up regulation of TSLP receptors on ILC2s may contribute to the pathogenic alteration. Treatment with anti-IL-5 monoclonal antibody in combination with dexamethasone effectively suppressed airway remodeling in the steroid-resistant model. Overall, IL-5 blockage could be a promising therapeutic strategy for steroid-resistant asthma.

Summary: Plasmalogen, localized in the raft of mammalian cell membranes, is involved in the storage of polyunsaturated fatty acids (PUFA) and is found to be more abundant in malignant cells surviving and growing in hypoxic conditions. In this study using liquid chromatography-tandem mass spectrometry, it was observed that the intracellular concentration of plasmalogen species containing a PUFA at the sn-2-position did not change for two days under hypoxic culture in human colorectal cancer-derived Caco2 cells. However, on the third day of hypoxia, there was a significant increase in ethanolamine plasmalogen and choline plasmalogen compared to the second day. This increase was suggested to be regulated by the up-regulation of mRNA of Ca2+-independent phospholipase A(2)beta and cytoplasmic phospholipase A(2)gamma, as well as the down-regulation of lysoplasmalogenase in Caco2 cells under hypoxia.

Summary: Ceramide plays a role in NCS-induced apoptosis by enhancing the assembly of ATM and MRN complex proteins. NCS increases ceramide production through the activation of nSMase and suppression of SMS, leading to the colocalization of ceramide with ATM and MRN complex. Inhibition of ceramide generation and nSMase activity can prevent the activation of ATM and apoptosis induced by NCS.

Summary: In this study, we found that phospholipase C-related catalytically inactive protein (PRIP) enhances cisplatin-induced apoptosis in breast cancer cells. PRIP promotes XIAP degradation by inhibiting PI (3,4,5)P3/AKT signaling, leading to enhanced cisplatin-induced apoptotic cell death. Therefore, PRIP1-PH liposomes may be a novel agent to avoid cisplatin resistance.

Summary: The antidepressant effects of ketamine may be related to both the dopaminergic system and the serotonergic system, while the effects of (R)-ketamine may be independent of the monoaminergic system. Ketamine metabolites differ in their ability to regulate monoamine neurotransmitters, and some metabolites may share common serotonergic signaling mechanisms with ketamine.

Summary: This study investigated the therapeutic effects of ceramide nanoliposomes (CNL) on type 2 inflammation-based asthma. The results showed that CNL treatment significantly decreased airway remodeling and suppressed goblet cell hyperplasia induced by ovalbumin challenges. This suggests that CNL may have therapeutic effects on airway diseases like asthma.
