The effects of protein binding on the activities of caspofungin, anidulafungin, and micafungin were evaluated against Candida and Aspergillus species. Adding human serum sharply increased the MICs of micafungin and anidulafungin and modestly affected the MIC of caspofungin. The increase in MICs does not appear consistent with the rate of protein binding for the three compounds.

Nucleotide-binding and leucine-rich repeat (NLR) proteins are essential intracellular immune receptors in both animal and plant kingdoms. Sensing of pathogen-derived signals induces oligomerization of NLR proteins, culminating in the formation of higher-order protein complexes known as resistosomes in plants. The NLR resistosomes play a pivotal role in mediating the plant immune response against invading pathogens.

This study aimed to evaluate the cholesterol-regulatory effects of lauric-acid-esterified octacosanol (LEO) and oleic-acid-esterified octacosanol (OEO) compared to their unmodified counterparts and to investigate the underlying mechanisms by partially substituting the fat content in obese C57BL/6J mice induced with a high-fat diet (HFD). Rice bran oil and coconut oil were also investigated as they are rich in oleic acid and lauric acid, respectively. The results showed that all supplemented groups significantly inhibited weight gain induced by the HFD, but the groups treated with esterified octacosanol exhibited a more pronounced effect.

Bruton's tyrosine kinase (BTK) is a major drug target in immune cells. The membrane-binding pleckstrin homology and tec homology (PH-TH) domains of BTK are required for signaling. Dimerization of the PH-TH module strongly stimulates the kinase activity of BTK in vitro.

Ovarian tissue cryopreservation addresses critical challenges in fertility preservation for prepubertal female cancer patients, such as the lack of viable eggs and hormonal deficiencies. However, mitigating follicle and granulosa cell damage during freeze-thaw cycles remains an urgent issue. Luteinizing hormone (LH), upon binding to luteinizing hormone receptors (LHR) on granulosa cells, enhances estrogen synthesis and secretion, contributing to the growth of granulosa cells and follicles.

ADAR is highly expressed and correlated with poor prognosis in hepatocellular carcinoma (HCC), yet the role of its constitutive isoform ADARp110 in tumorigenesis remains elusive. We investigated the role of ADARp110 in HCC and underlying mechanisms using clinical samples, a hepatocyte-specific knock-in mouse model, and engineered cell lines. ADARp110 is overexpressed and associated with poor survival in both human and mouse HCC.
