For this reason, Koonin described CRISPR-Cas as a Lamarckian inheritance mechanism. However, this was disputed by a critic who noted, "We should remember [Lamarck] for the good he contributed to science, not for things that resemble his theory only superficially.

The MDR phenotype is associated with overexpression of ABC transporters, involved in drug efflux. Metastasis originates from the epithelial-mesenchymal transition (EMT), in which cells acquire a migratory phenotype, …Transforming growth factor-β (TGF-β) is related to epithelial-mesenchymal transition (EMT) of lens epithelial cells (LECs) that is proven to induce PCO formation in clinical and experimental studies. In this study, CRISPR sequences targeting exon of TGF-βRII were knocked out with lentiviral transfection in LECs.The transforming growth factor beta (TGF-beta) signaling pathway is a type of signal transduction mechanism involved in many cellular processes, such as cell growth, cell differentiation, apoptosis, cellular homeostasis and other cellular functions.. This is a simplified version of the process (Figure 1): TGF-beta binds to TGF-beta receptors (first …The induction of EMT by TGF-β was first recognized in cell culture.
