REVIEW
Yi Xiong, Bi-Yun Huang, Ji-Ye Yin
Drug therapy for non-small cell lung cancer consists mainly of platinum-based chemotherapy regimens. However, toxicity, drug resistance, and high risk of death have been seen in the clinic, which means there is a need for optimizing the use of medications. Platinum resistance could be mediated by a series of DNA repair pathways, and therefore, these pathways should be taken into account for optimizing drug using. The goal of pharmacogenomics is to elucidate genetic factors, such as DNA repair genes, which might underlie drug efficacy and effectiveness, and to improve therapeutic effects or guide personalized therapy as well...

BACKGROUND: Statins can reduce reproductive damage induced by obesity or high-fat diet (HFD), but the specific regulatory mechanisms are largely unknown. Since mTOR/p70s6k sinaling promotes spermatogonia proliferation and spermatogenesis, we hypothesized that this pathway will be involved in the protective effects of statin in HFD-induced reproductive dysfunction. METHODS: Male Sprague Dawley rats (3 weeks old) were randomly divided into a control group (standard diet), HFD group, and a fluvastatin group (HFD + fluvastatin at 6mg/kg, once daily by oral gavage)...

BACKGROUND/AIMS: Recent studies have indicated that microRNA-21 (miR-21) is involved in the inflammatory response in relation to renal disease. Sirtuin1 (SIRT1) exerts renoprotective properties by counteracting inflammation. The activation of CD40 triggers inflammation that participates in renal inflammation and injury. The relationship between miR-21, SIRT1 and CD40, however, remains elusive. METHODS: Immunohistochemistry, small-interfering RNA (siRNA) transfection, quantitative real-time PCR and western blotting were applied to assess the morphological, functional and molecular mechanisms in primary cultured renal inner medullary collecting duct (IMCD) cells...

Mounting data points to epithelial plasticity programs such as the epithelial-mesenchymal transition (EMT) as clinically relevant therapeutic targets for the treatment of malignant tumors. In addition to the widely realized role of EMT in increasing cancer cell invasiveness during cancer metastasis, the EMT has also been implicated in allowing cancer cells to avoid tumor suppressor pathways during early tumorigenesis. In addition, data linking EMT to innate and acquired treatment resistance further points towards the desire to develop pharmacological therapies to target epithelial plasticity in cancer...

BACKGROUND: The proteasome exists in all eukaryotic cells and provides the main route of intracellular proteins degradation involved in cell growth and apoptosis. Proteasome inhibition could block protein degradation pathways and disturb regulatory networks, possibly leading to profound effects on cell growth, particularly in cancer cells. A proteasome inhibitor with an appropriate toxicity index for malignant cells rather than normal cells would be an attractive anticancer therapy. METHODS: The human osteosarcoma (OS) cell lines MG-63 and Saos-2 and normal osteoblast cells were used to study the antitumour activity of the proteasome inhibitor MLN9708/2238...

BACKGROUND: Bone morphogenetic protein 15 (BMP15) and growth differentiation factor 9 (GDF9) are members of the transforming growth factor beta (TGF-β) superfamily. Through autocrine and paracrine mechanisms, these two factors can regulate cell differentiation, proliferation, and other functions in the ovary locally. Furthermore, GDF9 and BMP15 play vital roles in follicular growth, atresia, ovulation, fertilization, reproduction, and maintenance. Numerous studies have demonstrated a synergy between BMP15 and GDF9...

Thiamine is one of several essential cofactors for ATP generation. Its deficiency, like in beriberi and in the Wernicke-Korsakoff syndrome, has been studied for many decades. However, its mechanism of action is still not completely understood at the cellular and molecular levels. Since it acts as a coenzyme for dehydrogenases of pyruvate, branched-chain keto acids, and ketoglutarate, its nutritional privation is partly a phenocopy of inborn errors of metabolism, among them maple syrup urine disease. In the present paper, we report metabolic and genomic findings in mice deprived of thiamine...

BACKGROUND/AIMS: The mechanisms underlying the protective role of heat acclimation (HA) in heat stroke (HS)-induced brain injury are still unclear. The autophagy-lysosome pathway is known to pay an important role in protecting stressed or diseased cells from death. Nevertheless, whether autophagy and lysosomes are involved in HA-mediated neuroprotection following HS exposure remains unclear. METHODS: The protective effects of HA were assessed by rectal temperature, hematoxylin-eosin staining, transmission electron microscopic analysis, terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling staining, and Fluoro Jade B staining, after mice were subjected to HS...

Stressful events during pregnancy adversely affect brain development and may increase the risk of psychiatric disorders later in life. Early changes in the kynurenine (KYN) pathway (KP) of tryptophan (TRP) degradation, which contains several neuroactive metabolites, including kynurenic acid (KYNA), 3-hydroxykynurenine (3-HK), and quinolinic acid (QUIN), may constitute a molecular link between prenatal stress and delayed pathological consequences. To begin testing this hypothesis experimentally, we examined the effects of a 2-h restraint stress on KP metabolism in pregnant FVB/N mice on gestational day 17...
