Mesenchymal stromal cells promote the formation of lung cancer organoids via Kindlin-2.

Background: Patient-derived lung cancer organoids (PD-LCOs) demonstrate exceptional potential in preclinical testing and serve as a promising model for the multimodal management of lung cancer. However, certain lung cancer cells derived from patients exhibit limited capacity to generate organoids due to inter-tumor or intra-tumor variability. To overcome this limitation, we have created an in vitro system that employs mesenchymal stromal cells (MSCs) or fibroblasts to serve as a supportive scaffold for lung cancer cells that do not form organoids.

A Bait-and-Hook Hydrogel for Net Tumor Cells to Enhance Chemotherapy and Mitigate Metastatic Dissemination.

: Lung cancer is an aggressive disease with rapid progression and a high rate of metastasis, leading to a significantly poor prognosis for many patients. While chemotherapy continues to serve as a cornerstone treatment for a large proportion of lung cancer patients, expanding preclinical and clinical evidence indicates that chemotherapy may promote tumor metastasis and cause side effects. : We develop an injectable bait-and-hook hydrogel (BH-gel) for targeted tumor cell eradication, which embedded doxorubicin liposomes as cytotoxic agents and CXCL12 as a chemoattractant to capture and kill tumor cells.

The Role of Scavenger Receptor BI in Sepsis.

Sepsis is a life-threatening condition resulting from a dysregulated host response to infection. Currently, there is no effective therapy for sepsis due to an incomplete understanding of its pathogenesis. Scavenger receptor BI (SR-BI) is a high-density lipoprotein (HDL) receptor that plays a key role in HDL metabolism by modulating the selective uptake of cholesteryl ester from HDL.

JM053 alleviates osteoporosis in rats by increasing the content of soy isoflavone aglycones in fermented soymilk.

JM053 has a significant ability to convert soy isoflavones and can be used as a fermentation strain to ferment soymilk, thereby increasing the content of free aglycones in soymilk and thus providing an effective method to alleviate osteoporosis symptoms. This study aims to establish a rat model of osteoporosis induced by dexamethasone (DEX) and clarify the alleviating effect of soymilk fermented with JM053 on osteoporosis. Research has shown that fermented soymilk with JM053 can inhibit weight loss in rats caused by DEX, regulate the expression of inflammatory factors such as tumor necrosis factor-α (TNF-α) towards normal levels, and increase levels of alkaline phosphatase (ALP) and osteocalcin (OCN) to promote bone synthesis.

Comparative study on pregnancy complications: PGT-A vs. IVF-ET with gender-specific outcomes.

The safety and clinical effectiveness of preimplantation genetic testing for aneuploidy (PGT-A) in improving pregnancy outcomes for sub-fertile patients remains controversial. Potential sex-based differences in the relationship between PGT-A and pregnancy complications have not been investigated, which could guide the appropriate clinical application of PGT-A. In this secondary analysis of data from a multicenter, randomized, controlled, non-inferiority trial (NCT03118141), 940 women who achieved singleton live birth during the trial were included to estimate the between-group differences in pregnancy complications following PGT-A versus conventional fertilization (IVF) vary with fetal sex.

Elevated free cholesterol levels due to impaired reverse cholesterol transport are a risk factor for polymicrobial sepsis in mice.

Dysregulated lipid metabolism is commonly observed in septic patients, but how it contributes to sepsis remains largely unknown. Reverse cholesterol transport (RCT) is crucial for regulating cholesterol metabolism in circulation. During RCT, high-density lipoprotein collects cholesterol from peripheral tissues and transports it to the liver's scavenger receptor BI (SR-BI), where SR-BI mediates the uptake of cholesteryl esters (CEs) from high-density lipoprotein for excretion via bile.
