Performance in the Laboratorysts) resulted in the transformation of 3T3 cells into focus-forming cells. Such focus-forming 3T3 cells first yielded the ras family (Harvey-, Kirsten-, N-ras) oncogenes. Co-transfection of such inoculated 3T3 cells into nude mice increased the sensitivity of the assay.变形 发表于 2025-3-27 16:38:11
Errors or Inherent Attributes for the Sustenance of Unicellular Lifephysiological “cell survival pathways” PI3K; Wnt/catenin; Notch, as a “destabilizer” of catenin; NFκB; TGFβ, discovered as decapentaplegic, Dpp; Hedgehog, JAK/STAT were already operational in the cnidaria (a non-bilaterian). The hoglet gene of the choanoflagellate, Monosiga ovata, may be the ancestor of the Hh gene family.很像弓] 发表于 2025-3-27 18:57:42

The First Cells Ascend. “.” (LUCA; the “C“ may stand also for the first “Cellular”) existed before the division of the first cellular elements into the three domains of life on Earth: archaea (C. Woese), prokaryotes (eubacteria), and eukaryotes.易于交谈 发表于 2025-3-28 11:05:47
The RNA/DNA Complex at Work.. The ancient unicellular life forms driven by the primordial DNA underwent mitoses in their mature age, thus escaping senescence and natural death. It is not possible to determine if the telomerases of ancient unicellular life forms acted constitutively in maintaining chromosome lengths (.).
