Phytochemical-Based Nanomedicine for Advanced Cancer Theranostics: Perspectives on Clinical Trials to Clinical Use.

In the current chapter, a new strategic compilation of phytochemicals with potent antitumor properties has been addressed, most importantly focusing on cell cycle arrest and apoptotic signaling mechanism. A promising approach in tumor prevention is to eliminate cancer cells preferably via cell cycle arrest and programmed cell death with lesser harm to neighboring normal cells. Cancer cells have a survival advantage to escape apoptosis and relentlessly divide to proliferate, gearing up the cell cycle process.

Ameliorating effect of CpG-ODN (oligodeoxynucleotide) against radiation-induced lung injury in mice.

While radiation-induced lung injury (RILI) is known to be progressed by Th2 skewed, pro-inflammatory immune response, there have been few therapeutic attempts through Th1 immune modulation. We investigated whether the immunostimulant CpG-oligodeoxynucleotide (CpG-ODN) would be effective against RILI by way of measuring reactive oxygen species (ROS) and nitric oxides (NO), histopathology, micro-three-dimensional computer tomography (CT), and cytokine profiling. We found that KSK CpG-ODN (K-CpG) significantly reduced histopathological fibrosis when compared to the positive control (PC) group (p < 0.

Immunotoxicity of titanium dioxide nanoparticles via simultaneous induction of apoptosis and multiple toll-like receptors signaling through ROS-dependent SAPK/JNK and p38 MAPK activation.

Background: Titanium dioxide nanoparticles (TiO NPs) represent a scientific breakthrough in the areas of biological and medicinal applications. Interaction of TiO NPs with components of innate immune system remains elusive.

Aim: This study explored in vitro immunotoxicity of murine macrophage RAW 264.

Implication of immunokine profiling for cancer staging.

Tumor may arise from the dysregulation of immune system, which plays pivotal roles in counteracting tumor colonization, late-stage tumors, and metastases. In the midst of the establishment of cancer in vivo, immune cells are activated to release a multitude of immunokines, such as cytokines, and chemokines. Thus, since cytokine levels in tumor bearing host would be differential among local (intratumoral lesion, peritumoral normal tissue), and systemic sample site (serum), these differences might be significantly correlated to prognosis and treatment outcome for cancer patients.
