Sophoricoside (SOP), an isoflavone glycoside isolated from seed of Sophora japonica L., has been reported to have various pharmacological activities, including anti-cancer, anti-allergy and anti-inflammation. However, the effect of SOP on lipopolysaccharides (LPS)-acute lung injury (ALI) is completely unclear.

Article Synopsis
  • Ferroptosis is a type of cell death linked to oxidative stress, and is important in conditions like acute lung injury (ALI) caused by seawater drowning.
  • Researchers tested the role of Nrf2, a protein that can suppress ferroptosis, using various methods, including activating or inhibiting Nrf2 in cells and animal models.
  • Results showed that activating Nrf2 improved cell survival and reduced harmful ROS levels, while deactivating it worsened lung injury, suggesting that Nrf2 is a potential target for treating ALI from seawater drowning.

Background: Hypoxia is commonly existed in tumors and lead to cancer cell chemo/radio-resistance. It is well-recognized that tumor hypoxia is a major challenge for the treatment of various solid tumors. Hyperoside (quercetin-3-O-galactoside, Hy) possesses antioxidant effects and has been reported to protect against hypoxia/reoxygenation induced injury in cardiomyocytes.

Epigallocatechin gallate (EGCG), a major polyphenol in green tea, exhibits diverse biological activities. Previous studies show that EGCG could effectively suppress HBV gene expression and replication, but the role of EGCG in HBV replication and its underlying mechanisms, especially the signaling pathways involved, remain unclear. In this study we investigated the mechanisms underlying EGCG inhibition on HBV replication with a focus on the signaling pathways.

Objective: Noninvasive prenatal detection of trisomy 21 (T21) has been achieved by measuring the ratio of two alleles of a single nucleotide polymorphism in circulating placenta specific 4 (PLAC4) mRNA in maternal plasma with a few assays in recent years. Our research is to explore the variations of PLAC4 mRNA expression level in maternal plasma with normal pregnancies in second trimester, which can provide pregnant women deeper insights with suitable detection period for the non-invasive prenatal detection of T21.

Methods: We measured a serial plasma PLAC4 mRNA concentrations weekly from the same 25 singleton normal pregnant women.

Aims: To investigate the impacts of cytomegalovirus (CMV) viral load, TORCH (toxoplasmosis, others, rubella, CMV and herpes) coinfections, CMV glycoprotein B (gB) genotypes and maternal genetic polymorphisms on pregnancy outcomes among CMV-infected women.

Methods: A total of 731 CMV-infected pregnant women (634 and 97 with normal and adverse pregnancy outcomes, respectively) were recruited. CMV load quantification and screening of TORCH coinfections were performed by using real-time polymerase chain reaction (PCR) and immunodetection techniques, respectively.

Purpose: To elucidate the clinicopathological significance and the role of Jun Activation Domain-Binding Protein 1 (JAB1), Ser10-phosphorylated p27 (p27S10), and total p27 in human hepatocellular carcinoma (HCC) prognosis.

Methods: We evaluated the expression of JAB1 and p27S10 in tissues by immunohistochemical and immunoblot analyses. p27 Ser10 phosphorylation and Ser10 phosphorylation-dependent p27-JAB1 interaction were demonstrated in proliferating Huh7 cells following transfection of pEGFP-p27WT/p27S10A/p27S10D plasmids and pcDNA3.

Objective: to investigate the expression of c-jun-activation-domain binding protein (JAB1) in hepatocellular carcinoma (HCC) and the clinicopathologic significance thereof.

Methods: Immunohistochemistry was used on 76 specimens of HCC tissues and native liver tissues adjacent to the HCC tissues, and 10 specimens of normal liver tissues near the liver angioma to detect the expression of JAB1 and the cell proliferative factor Ki67.

Results: The expression rate of JAB1 in the HHC tissues was 68.

Objective: To study the effect of all-trans retinoic acid (ATRA) on U937 cell growth and its mechanism.

Methods: Cell cycle was detected by flow cytometry (FCM), expressions of cell cycle associated protein and the p27 related protein were detected by Western blot. The binding of P27 and Skp2 was detected by immunoprecipitation.

Background & Objective: Arsenic trioxide (As(2)O(3)) is a new drug used to treat solid tumors. However, the mechanism is still unclear. This study was to investigate the effects of As(2)O(3) on the proliferation of human hepatocellular carcinoma (HCC) cell line SMMC-7721, and to explore the mechanisms.
