Manicone and colleagues found that fibrosis is elevated and persists in mice lacking the αE subunit (Itgae−/−), which only pairs with the β7 integrin subunit.
In contrast to V1 IN-ablated mice, the locomotor phenotype that persists in mice lacking V2b INs was much milder, with the most notable change being a prolongation of the stance phase that results in overextension of the ankle joint during walking.
Regarding the argument (B) that OSC are not essential for neo-oogenesis since the oocytes persist in ovaries lacking OSC, we recently demonstrated that in rat ovaries lacking OSC, the oocytes originate by an alternate pathway, from medullary somatic stem cells; primordial follicles are formed in the juxtaposed (deep) ovarian cortex [ 72].
Finally, we determine that even in the absence of Notch inhibition, neurogenesis does not persist in embryos lacking NvSoxB(2).
Consistent with the recent discovery that telomeric DSB's resist DNA repair (Fumagalli et al, 2012), our data demonstrate that telomeric DDR foci persisted in cells lacking hTERT activity while non-telomeric foci were resolved within days.
Second, depolarization-induced PKA transients were decreased in amplitude but, surprisingly, persisted in knockout mice lacking the calcium dependent adenylate cyclase AC1 and in double knockout mice lacking both AC1 and AC8.
Surprisingly, depolarization-induced calcium-dependent PKA transients persist in barrelless mice lacking AC1, the predominant calcium-dependent adenylate cyclase in RGCs, as well as in double knockout mice lacking both AC1 and AC8.
The isoflavonoid genistein facilitated opening of HCN1 and HCN2 channels, and this facilitation of channel opening persisted in HCN1 channels lacking only their CNBD, but not in channels missing the entire carboxy-terminal domain including the C-linker [32].
B) Oocytes persist in rat ovaries lacking ovarian surface epithelium (i.e. OSC).
The same study also showed that γH2AX foci, a widely used marker for DSBs, persisted for longer in MEFs lacking MUS81 [3].
Although SVR leads to improved quality of life in the short-term, data relating to whether or not this improvement persists in the long term are lacking.
