Deformation quantisation of the argument shift on $U\mathfrak{gl}(n)$

Argument shift algebras are the commutative subalgebras in the symmetric algebras of a Lie algebra, generated by the iterated derivations (in direction of a constant vector field) of Casimir elements in $S\mathfrak{gl}(n)$. In particular all these quasiderivations do mutually commute. In my talk I will show that a similar statement holds for the algebra $U\mathfrak{gl}(n)$ and its quasiderivations: namely, I will show that iterated quasiderivations of the central elements of $U\mathfrak{gl}(n)$ with respect to a constant quasiderivation do mutually commute. Our proof is based on the existence and properties of "Quantum Mischenko-Fomenko" algebras, and (which is worse) cannot be extended to other Lie algebras, but we believe that the fact that the "shift operator" can be raised to $U\mathfrak{gl}(n)$ is an interesting fact.
