Summary: This study found that Astragaloside IV (AS-IV) protected macrophages from oxLDL-induced apoptosis mediated by ER stress-CHOP through promoting autophagy, which may enhance the stability of atherosclerotic plaques.

Summary: This study found that the expression of the retrotransposon PEG10 is reduced in the placentas of patients with early-onset preeclampsia. In vitro studies suggest that hypoxia and inflammation may contribute to the downregulation of PEG10. Reduced PEG10 alters the canonical TGF-beta signaling and may be involved in trophoblast dysfunction.

Summary: This study found that high-density lipoproteins (HDL) partially decreased neutrophil extracellular trap (NET) formation induced by copper-oxidized low-density lipoprotein (oxLDL). It was also discovered that oxidized phosphatidylcholines and lysophosphatidylcholine in oxLDL promoted NET formation, which could be completely blocked by native HDL. Furthermore, an electronegative subfraction of LDL, LDL(-), was found to promote NET formation. These findings suggest that plasma lipoproteins and their oxidative modifications play multiple roles in promoting NET formation, and HDL acts as a suppressor of this response.

Summary: Autophagy is a crucial process in maintaining normal pregnancy, but it is impaired in preeclampsia. This study demonstrates that hypoxia-reoxygenation treatment disrupts the autophagic machinery in human trophoblasts, leading to the accumulation of protein aggregates. Similar features were observed in the placenta from early-onset preeclampsia deliveries. Evaluation of key regulators and verification of autophagic ultrastructure are essential for accurately assessing autophagy activity in human trophoblasts and placental tissue from preeclampsia deliveries.

Summary: Elevated HDL-C is associated with improved cardiovascular outcomes, but clinical trials targeting HDL-C have not been successful. Rare compound heterozygous variants in SCARB1 have been found to cause severe CAD through Mendelian inheritance. These findings support the disease-contributing capability of loss-of-function SCARB1 variants.

Summary: The study found that early-onset severe preeclampsia and late-onset severe preeclampsia have different molecular mechanisms, with the former associated with metabolism-related pathways and the latter with immune-related pathways. Some key transcription factors may be driving the widespread gene dysregulation in both early-onset and late-onset patients.

Summary: Emodin can alleviate impairment induced by acute hypoxia in gibel carp by inhibiting hypoxia signaling and reducing oxidative damage. It also inhibits endoplasmic reticulum stress, enhances autophagy, inhibits apoptosis, and functions through the AMPK/mTOR pathway.

Summary: This study found that the level of N6-methyladenosine (m6A) in placental tissue of early-onset preeclampsia (ePE) patients was reduced. Wilms' tumor 1-associating protein (WTAP), a regulator of m6A, was found to regulate trophoblast cell migration and invasion. The study also revealed the interaction between WTAP and the high mobility group nucleosomal binding domain 3 (HMGN3) gene, and the effect of m6A on the stability of HMGN3 mRNA. WTAP enhanced the stability of HMGN3 mRNA by binding to its m6A site, and HMGN3 was recognized and regulated by insulin-like growth factor 2 mRNA-binding protein 1 (IGF2BP1). The results suggest that m6A modification plays an important role in the pathogenesis of ePE.

Summary: Lung cancer is a malignant tumor with high morbidity and mortality rates worldwide. The current chemotherapy for lung cancer is ineffective due to drug resistance. Tripchlorolide (T4), a natural extract, has been found to have immunosuppressive and antitumor effects, making it a potential therapeutic agent for lung cancer. This study investigated the effect of T4 on reducing chemoresistance in lung cancer cells and explored the underlying mechanism. The results showed that T4 can increase the sensitivity of lung cancer cells to cisplatin, a chemotherapy drug, by reducing the expression of AEG-1 protein.

Summary: Preeclampsia, a common obstetrical complication, is linked to abnormal placental development and cellular health, with nutritional adequacy playing a crucial role. Cellular components' structural integrity affects physiological cell death mechanisms, while nutritional deficiencies can disrupt these processes, leading to poor trophoblast invasion and differentiation in preeclampsia.

Summary: Preeclampsia is a severe complication of pregnancy, and finding predictive biomarkers is crucial for prevention. This study compared the diagnostic accuracy of carbonic anhydrase IX (CAIX) and sFlt1/PlGF ratio as biomarkers for predicting preeclampsia. CAIX levels significantly increased before the onset of preeclampsia, and it performed better than sFlt1/PlGF ratio in predicting the disease. CAIX could be an effective predictive biomarker for preeclampsia, but further studies are needed to confirm this finding.

Summary: SARS-CoV-2 infection in pregnant women leads to alterations in maternal and placental function, increasing the risk of preterm birth and caesarean delivery. Placentas of infected mothers show signs of vasculopathy and inflammation. The impact of maternal infection on the fetus and postnatal health is still unclear.
