This study describes the sensitization mechanism to thermal stress by histone deacetylase inhibitors (HDACIs) in lung cancer cells and shows that Ku70, based on its acetylation status, mediates the protection of lung cancer from hyperthermia (42.5°C, 1-6 hrs). Ku70 regulates apoptosis by sequestering pro-apoptotic Bax. However, its role in thermal stress is not fully understood. The findings sh...

BACKGROUND Knowledge that liver tumours preferentially take their blood supply from the arterial blood supply rather than the portal venous system can be used for local delivery of treatment or for embolisation to cut off the blood supply to tumours. AIMS To present histological evaluation of malignant and non-malignant hepatic tissue of one such therapy, selective internal radiation therapy ...

PURPOSE Selective internal radiotherapy (SIRT) with yttrium-90 ((90)Y) resin microspheres can improve the clinical outcomes for selected patients with inoperable liver cancer. This technique involves intra-arterial delivery of β-emitting microspheres into hepatocellular carcinomas or liver metastases while sparing uninvolved structures. Its unique mode of action, including both (90)Y brachyther...

The experimental process of collecting images from macromolecules in an electron microscope is such that it does not allow for prior specification of the angular distribution of the projection images. As a consequence, an uneven distribution of projection directions may occur. Concerns have been raised recently about the behavior of 3D reconstruction algorithms for the case of unevenly distribu...

Current studies have indicated the association of chronic sterile inflammation (inflammation in the absence of pathogens) with the pathogenesis of age-related and metabolic diseases. The inflammation is under the control of transcription factor NF-κB through an antagonistic crosstalk between SIRT1, PARP-1, and -2 signaling pathways. The transcriptional activity of NF-κB is increased in various ...

Objective: Mangiferin (MGF) is a natural xanthone, with regulation effect on lipid metabolism. However, the molecular mechanism remains unclear. We purposed after oral administration, MGF is converted to its active metabolite(s), which contributes to the effects on lipid metabolism. Methods: KK-Ay mice were used to validate the effects of MGF on lipid metabolic disorders. Liver biochemical indi...
