Modeling long-term longitudinal HIV dynamics with application to an AIDS clinical study

open access: yes, 2009
A virologic marker, the number of HIV RNA copies or viral load, is currently used to evaluate antiretroviral (ARV) therapies in AIDS clinical trials. This marker can be used to assess the ARV potency of therapies, but is easily affected by drug exposures,

Integrative systems‐level analysis reveals a contextual crosstalk between hypoxia and global metabolism in human breast tumors

open access: yesMolecular Oncology, EarlyView.
Breast tumor samples scored for metabolic deregulation (M1 to M3) were given a hypoxia score (HS). The highest HS occurred in patients with strongest metabolic deregulation (M3), supporting tumor aggressiveness. HS correlated with the highest number of metabolic pathways in M1. This suggests hypoxia to be an early event in metabolic deregulation.

Characterization of heme binding to recombinant α1-microglobulin

open access: yesFrontiers in Physiology, 2014
Background: Alpha-1-microglobulin (A1M), a small lipocalin protein found in plasma and tissues, has been identified as a heme and radical scavenger that may participate in the mitigation of toxicities caused by degradation of hemoglobin.

Crosstalk between gut microbiota and tumor: tumors could cause gut dysbiosis and metabolic imbalance

open access: yesMolecular Oncology, EarlyView.
In this research, we analyzed the relationship between gut microbiota and tumor. We discovered that both subcutaneous and metastatic tumors would alter the composition and metabolic function of gut microbiota. Meanwhile, fecal microbiota transplantation also indicated the anti‐tumor role of the gut microbiota, revealing the crosstalk between tumor and ...

Application of morbid animal model in drug safety evaluation of TCM

open access: yesFrontiers in Pharmacology, 2015
Further toxicology research of TCM new drugs is still necessary in animals. In some cases, it is necessary to pay more attention to the use of morbid animals in pre-clinical safety research in despite of some deficiencies.
