Scientists found that deletion of Erk1/2 in intestinal epithelial cells at embryonic stages resulted in an unexpected increase in cell proliferation and migration, expansion of intestinal stem cells and formation of polyp-like structures, leading to postnatal death.

miRNA microarray analysis showed that miR-4634 levels in A549 cells increased significantly after everolimus treatment. Decreased expression of miR-4634 was also found in non-small-cell lung carcinoma cell lines and patients’ tumors by qPCR.

Smurf1 promotes cell growth and colony formation by accelerating cell cycle and aberrant signaling pathways. In addition, the authors showed that Smurf1 ubiquitylates and degrades phosphatase and tensin homolog.
Investigators demonstrated that progesterone receptor membrane component 1 played a prominent role in regulating the growth of cancer cells by altering the PI3K/AKT/mTOR and EGFR signalling mechanisms in both ER-positive and TNBC cells.

A series of fluorescent thiazole–pyrazoline derivatives was synthesized and their structures were characterized by 1H NMR, 13C NMR, and HRMS. Biological evaluation demonstrated that these compounds could effectively inhibit the growth of human non-small cell lung cancer A549 cells in a dose- and time-dependent manner in vitro and inhibit tumor growth in vivo.

Researchers used genetic and pharmacological inhibition of N-myristoyltransferase-1 (NMT1) to further dissect the role of this enzyme in cancer, and found an unexpected essential role for NMT1 at promoting lysosomal metabolic functions.
Researchers report for the first time that DHW-208 suppressed the growth of human breast cancer cells by inhibiting the PI3K/AKT/mTOR-signaling pathway both in vivo and in vitro.
