Description
Although LIPUS has been shown to enhance fracture healing, the underlying mechanism of LIPUS remains to be fully elucidated. Here, to understand the molecular mechanism underlying cellular responses to LIPUS, we investigated gene expression profiles in mouse MC3T3-E1 preosteoblast cells using a GeneChip system.

Description
Hyperthermia is widely used to treat patients with various cancers. 42.5C is well known as the inflection point of hyperthermia and generally up to 42C of hyperthermia is used in clinical cases combined with other therapies. Here, the effects of heat stress at 42 or 44C for 15 min on the gene expression in human lymphoma U937 cells were investigated using an Affymetrix GeneChip system. The cells were treated with heat stress (42 or 44C for 15 min), followed by incubation for 0, 1, 3 or 6 h at 37C. The percentage of DNA fragmentation was 8.4 2.2 (mean SD) at 42C for 6 h and 21.0 2.0 at 44C for 6 h. Of approximately 47,000 probe sets analyzed, many genes that were differentially expressed by a factor 2.0 or greater were identified in the cells treated with heat stress at 42 and 44C.

Description
Hyperthermia (HT) treatments in combination with either chemotherapy, radiotherapy or both are used for patients with cancer in various organs. However, the acquisition of thermotolerance in cancer cells due to the increase in cytoprotective proteins attenuates the therapeutic effects of HT. BAG3 (BCL2-associated athanogene 3) is a cytoprotective protein that acts against various stresses including heat stress. Recently, we demonstrated that the inhibition of BAG3 improves cell death sensitivity to HT in cancer cells. However, a detailed molecular mechanism involved in the enhancement of HT sensitivity by BAG3-knockdown (KD) in cancer cells is unclear.

Description
Diet-induced obesity is reported to induce a phenotypic switch in adipose tissue macrophages from an antiinflammatory M2 state to a proinflammatory M1 state. Telmisartan, an angiotensin II type 1 receptor antagonist and a peroxisome proliferator-activated receptor-gamma (PPAR-gamma) agonist, reportedly has beneficial effects on insulin sensitivity. We studied the effects of telmisartan on the adipose tissue macrophage phenotype in high fat-fed mice. Telmisartan was administered for 5 weeks to high fat-fed C57BL/6 mice. Insulin sensitivity, macrophage infiltration, and the gene expressions of M1 and M2 markers in epididymal fat tissues were examined. Insulin- or a glucose-tolerance test showed that telmisartan treatment improved insulin resistance, decreasing the body weight gain, visceral fat weight and adipocyte size without affecting the amount of food intake. Telmisartan treatment reduced the number of CD11c-positive cells and crown-like structures. Telmisartan reduced the mRNA expressions of M1 macrophage markers, such as TNF-alpha and IL-6, and increased the expression of M2 markers, such as IL-10 and Mgl2. The reduction of M1 macrophage markers, as well as the increased gene expression of M2 markers especially IL-10, is a possible mechanism for the improvement of insulin sensitivity by telmisartan.

Description
We performed global scale microarray analysis to identify detailed mechanisms by which nonpermissive temperature induces cell differentiation in testicular Sertoli TTE3 cells harboring temperature-sensitive SV40 large T-antigen by using an Affymetrix GeneChip system. Testicular Sertoli TTE3 cells used in the present study were derived from transgenic mice harboring a temperature-sensitive simian virus 40 large T-antigen. In the TTE3 cells, inactivation of the T-antigen by a nonpermissive temperature at 39C led to cell differentiation accompanying elevation of transferrin and cyclin-dependent kinase inhibitor CDKN1A. Of the 22, 690 probe sets analyzed, nonpermissive temperature up-regulated 729 probe sets and down-regulated 471 probe sets by >2.0-fold.

The 42.5C is well known as inflection point of hyperthermia and generally up to 42C of hyperthermia is used in clinical case to combine with other therapy. Here, the effects of heat stress at 42 or 44C for 90 min on the gene expression in HSC-3 human oral squamous carcinoma cells were investigated using an Affymetrix GeneChip system. The cells were treated with heat stress (42 or 44C for 90 min) and followed by incubation for 0, 6, or 12 h at 37C. The percentage of cell death was 5.0 1.5 (mean SD) at 42C for 12 h and 17.4 0.6 at 44C for 12 h. Of approximately 47,000 probe sets analyzed, many genes that were differentially expressed by a factor 2.0 or greater were identified in the cells treated with heat stress at 42 and 44C.

Description
Although an appropriate range of fluoride is thought to be safe and effective, excessive fluoride intake results in toxic effects in either hard tissues of teeth and skeleton or soft tissues of kidney, lung and brain. It is also well known that fluoride at a millimolar range elicits the complex cellular responses such as enzyme activity, signal transduction and apoptosis in many kinds of cells. However, its toxic effects are still unclear.

Description
Cold atmospheric pressure plasma (CAP) is known as a source of biologically active agents, such as reactive oxygen species (ROS) and reactive nitrogen species (RNS). Recent medical investigations have focused on applying CAP to cancer treatment. There is also growing evidence that exposure of cells to CAP or CAP-activated medium induces apoptosis in cancer cells, and ROS and/or RNS are considered to be effective agents to CAP-induced apoptosis. More recently, we demonstrated that Ar-CAP or Ar containing 2.5 % of N2 (Ar-N2-CAP) significantly induced apoptosis in human lymphoma U937 cells. However, a detailed molecular mechanism underling the induction of apoptosis by CAP in cancer cells is unclear.
