TGF-β1 could reduce cell viability and induce apoptosis, while these effects could be reversed by downregulation of GAS5 or HDAC4. Mechanically, GAS5 acted as a sponge for miR-217 to regulate the expression of HDAC4. Furthermore, overexpression of HDAC4 rescued the effects of GAS5 knockdown on viability and apoptosis of TGF-β1-induced BEAS-2B cells. GAS5 knockdown induced cell viability and hampered cell apoptosis in TGF-β1-stimulated BEAS-2B cells by regulating the miR-217/HDAC4 axis. The lncRNA GAS5/miR-217/HDAC4 axis played an important role in regulating TGF-β1-induced bronchial epithelial cells injury, thus contributing to asthma. The lncRNA GAS5/miR-217/HDAC4 axis played an important role in regulating TGF-β1-induced bronchial epithelial cells injury, thus contributing to asthma. Expansion of CD8 cytotoxic Tlymphocytes is a prerequisite for anti-cancer immune activity and has gained interest in the era of immune checkpoint therapy. To understand the CD8 T cell dynamics in the tumor microenvironment, we used multiplex fluorescence immunohistochemistry to quantitate CD8 proliferation (Ki67 co-expression) in tissue microarrays from 1107 colorectal, 642 renal cell, 1066 breast, 375 ovarian, 451 pancreatic and 347 gastric cancer samples. The density and the percentage of proliferating (Ki67 ) CD8 T cells were bothhighly variable between tumor types as well as between patients with the same tumor type. Elevated density and percentage of proliferating CD8 cytotoxic T cells were significantly associated with favorable tumor parameters such as low tumor stage, negative nodal stage (p ≤ 0.0041 each), prolonged overall survival (p ≤ 0.0028 each) and an inflamed immune phenotype (p = 0.0025) in colorectal cancer and, in contrast, linked to high tumor stage, adva
