  The recent discovery of nonzero $\theta_{13}$ (equal to Cabbibo angle
$\theta_C$ up to a factor of $\sqrt{2}$), the masses of supersymmetric
particles $\gapp$ TeV from LHC data, and the sum of three active neutrino
masses $\sum_i m_{\nu_i}\lapp 1$ eV from the study of large scale structure of
the universe motivate to study whether quark and lepton mixing have the same
origin at the grand unification scale. We find that both results from neutrino
experiments and LHC are complementary in quark-lepton unified model. A new
constraint on SUSY parameters appears from electroweak symmetry breaking with a
new correlation between the lower bounds on sparticle masses and the upper
bound on $\sum_i m_{\nu_i}$. In addition, we find that only $\mu>0$ (which is
favored by $(g-2)$ of muon) is allowed and $m_{\tilde q, \tilde \l} \gapp$ TeV
if $\sum_i m_{\nu_i} \lapp 1$ eV. On the other hand, a small change in lower
limit on $\theta_{13}$ from zero leads to a large increase in lower limits on
sparticles masses ($\gapp 2$ TeV), which are also the bounds if recently
discovered boson at LHC with mass around 125 GeV is the Higgs boson.
