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 of IL-6. Transient release and short-term acute action have positive effects, by increasing the source of progenitors for regeneration and growth in skeletal muscle. This also affects metabolic processes in other organs, since it stimulates glucose production. In different circumstances, chronically elevated levels of IL-6 have negative consequences, promoting muscle atrophy through different mechanisms not completely yet elucidated. These antithetical effects can also be a key to the several discrepancies observed with different experimental approaches aimed to decipher the IL-6/JAK/STAT role in skeletal muscle functions. Moreover, the different cell and tissue compartments where IL-6 is produced and acts can account for the conflicting effects observed on muscle repair, growth, and wasting. Additionally, a role in these dichotomous outcomes can also be car...
CONCLUSION: With the increased use of immunotherapeutic agents, increased awareness and early recognition are required for effective management of irAEs. Our experience as a single institution might be of use for health care providers in oncology. PMID: 32935638 [PubMed - as supplied by publisher]

Authors: Wan S, Zhao H Abstract The present study aimed to explore the diagnostic and prognostic value of lncRNA maternally expressed 3 (MEG3) in cervical cancer. Eighty-four patients with cervical cancer from February 2013 to March 2014 were enrolled in the observation group (OG), and another 58 female subjects who underwent physical examination at Huangshi Central Hospital were enrolled as the control group (CG). The serum MEG3 expression of patients in the two groups was detected by RT-qPCR, and the ability of MEG3 to aid in the diagnosis of cervical cancer, lymph node metastasis and FIGO staging, as well as to ...
In conclusion, SLC17A9 can be used as a new molecular marker to predict the poor prognosis of patients with HCC. PMID: 32934749 [PubMed]
In conclusion, the present study revealed that linalool inhibits T-ALL cell survival with involvement of the MAPK signaling pathway. JNK activation and ERK inhibition may play a functional role in apoptosis induction of T-ALL cells. Linalool may be developed as a novel anti T-ALL agent. PMID: 32934748 [PubMed]
In conclusion, psychological stress was more prominent in younger patients with stage IV breast cancer treated with hormonal therapy compared with elderly patients. Importantly, improving QOL within the 3 months after treatment initiation could lead to longer PFS rate. PMID: 32934747 [PubMed]
Authors: Verma A, Najahi-Missaoui W, Cummings BS, Somanath PR Abstract Metastatic prostate cancer (PCa) has a very high mortality rate in men, in Western countries and lacks reliable treatment. The advanced-stage PCa cells overexpress P21 (RAC1) activated kinase-1 (PAK1) and secreted phospholipase A2 (sPLA2) suggesting the potential utility of pharmacologically targeting these molecules to treat metastatic PCa. The small molecule, inhibitor targeting PAK1 activation-3 (IPA3) is a highly specific allosteric inhibitor of PAK1; however, it is metabolically unstable once in the plasma thus, limiting its utility as a ch...
In conclusion, high expression levels of eIF4A2 are associated with a poor prognosis and may be used as a potential prognostic indicator in patients with ESCC. PMID: 32934744 [PubMed]
Authors: Li DK, Wang W Abstract Cluster of differentiation 40 (CD40) mediates many immune activities. Preclinical studies have shown that activation of CD40 can evoke massive antineoplastic effects in several tumour models in vivo, providing a rationale for using CD40 agonists in cancer immunotherapy. To date, several potential agonistic antibodies that target CD40 have been investigated in clinical trials. Early clinical trials have shown that the adverse events associated with agonists of CD40 thus far have been largely transient and clinically controllable, including storms of cytokine release, hepatotoxicity an...
