PIN1 is located only at the basal (rootward) side of the central cylinder cell, PIN2 proteins at the apical (shootward) and lateral (inward) cell sides of the epidermis, and PIN3 is expressed and localized ubiquitously (Fig. 1B).

Third, exogenous application of FMRFamide evoked an inward current only in cells that were transfected with the FMRFamide receptor, but not in untransfected cells (Figure 4G).
Since we measured reduced excitability also at the cell level (Fig. 4), and since the increase in input conductance we observed is also a major factor in cell excitability, weaker synapses could contribute to reduced excitability, but the intrinsic properties of the cell, increased inward rectification and increased HCN currents, probably play a major role.
In cells transfected with pSM30-miR-212 the whole-cell inward current was smaller in amplitude to that in cells transfected with pSM30-SCR.
Benzamil significantly inhibited the inward whole-cell current (carried mostly by bath Na+ at -100 mV) by 87.5%; from I-100 = -2044 ± 552 pA to -255 ± 57 pA (n = 6).
Benzamil had no significant effect on the inward whole-cell current (carried mostly by bath K+ at -100 mV) (mean decreased insignificantly by 9.8%; from I-100 = -476 ± 112 pA to -429 ± 130 pA, n = 8).
Benzamil was used throughout these experiments at a concentration (1 μM) that yielded a complete inhibition of the transepithelial current [ 5] and significantly inhibited the inward whole-cell current (at -100 mV; I-100) by 48.5%; from -1305 ± 277 pA to -671 ± 146 pA (n = 7).
Functional expression of transfected wild type PKD2 in HEK cells has been shown [ 32]. Figure 3 shows that stable expression of wild type PKD2 in HEK cells resulted in a significant increase in the current amplitude of whole cell inward currents recorded either in normal extracellular tyrode solution or symmetrical K+.
In the cell, the inward-directed Na+gradient drives citrate uptake, but all steps are in principle reversible.
Our housing unit is built kind of like a horseshoe, with two levels of inward-looking cells and a third in the middle that all the other cells face; it's there that we tend to sit, in a communal area called base.
As expected, HEK293 clones expressing wild-type PKD2 displayed an increase in the current amplitude of whole cell inward and outward currents recorded either in normal extracellular tyrode solution or symmetrical K+.

Since I tried Ludwig back in 2017, I have been constantly using it in both editing and translation. Ever since, I suggest it to my translators at ProSciEditing.
