Comparison of hypocrellin B-mediated sonodynamic responsiveness between sensitive and multidrug-resistant human gastric cancer cell lines

ConclusionsThese results suggest that HB-SDT could induce apoptosis in SGC7901 and SGC7901/ADR cells via production of ROS. SGC7901/ADR was found to be more sensitive to HB-SDT than SGC7901 cells under the same experimental condition. Meanwhile, a noteworthy difference in cell membrane injury between SGC7901 and SGC7901/ADR cells was detected. The decreased membrane fluidity in SGC7901/ADR cells may be one of the reasons for its increased membrane damage.

In conclusion, MRP1 and MRP4 play an important role in the lack of response of GAC to drugs that are transported by these export pumps. Moreover, agents, such as sorafenib, considered at present useless to treat GAC, may become active antitumor drugs when co-administered with non-toxic MRP inhibitors, such as diclofenac.

Lei Shang1,2 and Minjie Wei1* 1School of Pharmacy, China Medical University, Shenyang, China 2Shenyang Medical College, Shenyang, China The protein lysine methyltransferase SMYD2 has recently emerged as a new enzyme modulate gene transcription or signaling pathways, and involved into tumor progression. However, the role of SMYD2 in drug resistant is still not known. Here, we found that inhibition of SMYD2 by specific inhibitor could enhance the cell sensitivity to cisplatin (CDDP), but not paclitaxel, NVB, and VCR in non-small cell lung cancer (NSCLC). Further study showed that SMYD2 and its substrates were overex...

Discussion Suppressor of cytokine signaling 1 is an essential molecule for maintaining immune homeostasis and subverting inflammation. Disorders arising from excess inflammation or SOCS1 deficiency can be potentially treated with SOCS1 mimetics (Ahmed et al., 2015). While SOCS1 has promising potential in many disorders, it should be noted that new targets and actions of SOCS1 are still being discovered and not all the effects of this protein are beneficial in autoimmune diseases and cancer. For instance, SOCS1 degrades IRS1 and IRS2, required for insulin signaling, via the SOCS Box domain, thus, limiting its potential in ...

In conclusion, osmotic burst of inflated complement-damaged cells may occur, but these bursts are most likely a consequence of metabolic collapse of the cell rather than the cause of cell death. The Complement Cell Death Mediator: A Concerted Action of Toxic Moieties Membrane pores caused by complement were first visualized by electron microscopy on red blood cell membranes as large ring structures (22). Similar lesions were viewed on E. coli cell walls (23). Over the years, ample information on the fine ultrastructure of the MAC that can activate cell death has been gathered (24) and has been recently further examined (...

Abstract Sorcin (Soluble resistance related calcium binding protein) is a small soluble penta EF family (PEF) of calcium (Ca2+) binding protein (22,000 Da). It has been reported to play crucial roles in the regulation of calcium homeostasis, apoptosis, vesicle trafficking, cancer development, and multidrug resistance (MDR). Overexpression of sorcin has been reported to be associated with different cancers such as breast cancer, colorectal cancer, gastric cancer, leukemia, lung cancer, nasopharyngeal cancer, ovarian cancer, etc. Essentially, expression of sorcin has been found to be elevated in cancer cells as comp...
