Researchers demonstrated that tissue‑specific transplantation antigen P35B (TSTA3) was regulated by miR‑125a‑5p and functions as an oncogene in lung cancer via promoting the activation of β‑catenin signaling.
Insmed Incorporated announced that Japan’s Ministry of Health, Labour and Welfare has approved ARIKAYCE ® for the treatment of patients with nontuberculous mycobacterial lung disease caused by Mycobacterium avium complex who did not sufficiently respond to prior treatment with a multidrug regimen. The launch of ARIKAYCE in Japan is anticipated in mid-2021.

The authors reviewed the functions and mechanisms of glucose-regulating protein 78 (GRP78) in the pathological processes of lung cancer, including tumorigenesis, apoptosis, autophagy, progression, and drug resistance, giving a comprehensive understanding of the function of GRP78 in lung cancer. They also discussed the potential role of GRP78 as a prognostic biomarker and therapeutic target for lung cancer.

miR‑454‑3p overexpression led to the suppression of proliferation, migration, and invasion in A549 and NCI‑H1650 cells. The overexpression of miR‑454‑3p in A549 and NCI‑H1650 cells significantly inhibited EMT. TGFB2 was revealed to be a direct target of miR‑454‑3p by using TargetScan database and luciferase reporter assay.
Investigators showed that polyphenol-rich sugarcane extract exerted anti-cancer properties on a range of cancer cells including human and mouse colon cancer cells lines; human lung cancer, human ovarian cancer, pro-monocytic human leukemia and mouse melanoma cell lines
