“…YXQ-EQ has been shown to regulate signaling pathways and gene expression in normal and malignant cells [4,5,6,7,18]. YXQ-EQ exerts potent cytotoxic effect on a variety of cancer cells and the underlying molecular mechanisms have recently begun to be addressed [4,5,6,7]. No cytotoxicity to normal cells was observed in these studies with YXQ-EQ.…”

“…The concept “External Qi of Qigong” refers to the technology and ability of “Qi deployment” therapy and health preservation of traditional Chinese medicine [4,5,6,7]. External Qi therapy has been used as one of the medical practices in China for thousands of years and is under management of the Chinese health authorities [8].…”

Background/Aims: Colorectal cancer (CRC) is the second leading cause of cancer death in the Western countries. Novel approaches of treatment are needed for CRC. The purpose of the present study was to investigate cytotoxic effect of external Qi of Yan Xin Qigong (YXQ-EQ) on human colorectal cancer cells. Methods: The effect of YXQ-EQ on viability, cell cycle progression and apoptosis in colorectal cancer HT-29 cells was investigated. Phosphorylation of Akt and Erk1/2, activation of NF-ĸB and the expression of proteins involved in regulation of cell cycle and apoptosis were examined by Western blot analysis. Results: YXQ-EQ markedly decreased viability and blocked colony formation of HT-29 cells. YXQ-EQ downregulated cyclin D1 expression and increased accumulation of cyclin-dependent kinase inhibitors p21^Cip1 and p27^Kip1, resulting in G1 cell cycle arrest. YXQ-EQ induced apoptosis in HT-29 cells in association with decreased expression of antiapoptotic proteins Bcl-xL, XIAP, survivin and Mcl-1 and elevated expression of proapoptotic protein Bax. YXQ-EQ significantly repressed phosphorylation of Akt and Erk1/2 and NF-ĸB activation in HT-29 cells, suggesting that YXQ-EQ may exert cytotoxic effect through regulating signaling pathways critical for cell proliferation and survival. Furthermore, YXQ-EQ treated PBS and an YXQ-EQ treated plant extract induced apoptosis in HT-29 cells. Conclusion: These findings show that YXQ-EQ has potent cytotoxic effect on HT-29 cells and suggest that YXQ-EQ could be potentially used for colorectal cancer treatment either directly or indirectly via carriers.

Objective. The aim of this study was to evaluate changes in the expression of genes associated with cellular stress response in peripheral mononuclear blood cells (PMBC) in healthy women. Materials and method. The experiment took place at the Japanese Martial Arts Centre "DOJO" in Stara Wieś, Poland, conducted over the course of a 4-day qigong training session. To evaluate the genes effect of this training, blood samples were taken before and after the training period. This experiment involved 20 healthy women (aged 56.2±9.01, body height 164.8±6.5 and mass 65.5±8.2). To determine the expression of HSF-1, HSPA1A, NF-kB, IL10 and CCL2 mRNA, 3 ml of venous blood was collected. The blood samples were placed in tubes allowing for separation (BD Vacutainer CPT
