The JAK/STAT Pathway in Skeletal Muscle Pathophysiology
Conclusion and Perspectives The IL-6/JAK/STAT signaling cascade plays a dominant role in skeletal muscle pathophysiology. IL-6 autocrine, paracrine, and endocrine functions assign to its downstream effectors pivotal importance in skeletal muscle-wasting-associated diseases and other multiple system diseases where muscle acts in communication with other organs. Targeting the components of the JAK/STAT pathway recently emerged as a strategic approach for the treatment of inflammatory diseases and human cancer. This review highlights the opposite outcomes on muscle biology caused by the amount of local and systemic release ...

Inhibition of SMYD2 Sensitized Cisplatin to Resistant Cells in NSCLC Through Activating p53 Pathway
In conclusion, the present study elucidated that the activity of SMYD2 in NSCLC may affect the cell sensitivity to chemotherapeutic agents, especially to CDDP. The elevated SMYD2 mediated CDDP resistance and malignant phenotype in NSCLC, indicating that SMYD2 may be a useful biomarker of CDDP resistance in NSCLC. Inhibition of SMYD2 contributes to the methylation-related activation of p53 and thus results in cell apoptosis. Furthermore, combination treatment with CDDP and an SMYD2 inhibitor had a synergistically antitumor effects in a xenograft model in vivo. Given that SMYD2 has reversible effects and is a targetable prot...

PGC1 β Regulates Breast Tumor Growth and Metastasis by SREBP1-Mediated HKDC1 Expression
Conclusions: PGC1β regulates breast cancer tumor growth and metastasis by SREBP1-mediated HKDC1 expression. This provides a novel therapeutic strategy through targeting the PGC1β/HKDC1 signaling pathway for breast cancer treatment. Introduction Breast cancer is a very common cancer with significant premature mortality in women. Around 12% of women in USA will have chance to be diagnosed with breast cancer during their lifetimes (1, 2). The development of breast cancer is regulated by many factors, and even as average survival rates have increased significantly as a result of many advanced treatments...
