CORE GREML for estimating covariance between random effects in linear mixed models for complex trait analyses

open access: yesNature Communications, 2020
Linear mixed models have bias due to the assumed independence between random effects. Here, the authors describe a genome-based restricted maximum likelihood, CORE GREML, which estimates covariance between random effects.

Efficient Implementation of the New Restricted Maximum Likelihood Algorithms

open access: yesJournal of Dairy Science, 1989
Abstract Recently tridiagonalization and diagonalization have been proposed as methods to speed the EM algorithm for variance component estimation in restricted maximum likelihood. These methods require approximately the same computing resources, but only if the most efficient strategies are employed.

Consistency and asymptotic normality of the maximum likelihood estimator in a zero-inflated generalized Poisson regression [PDF]

open access: yes, 2005
Poisson regression models for count variables have been utilized in many applications. However, in many problems overdispersion and zero-inflation occur.

A novel quinazolinone insulin receptor inhibitor and its synergy with an EGFR inhibitor in glucose‐driven glioblastoma

open access: yesMolecular Oncology, EarlyView.
The novel styrylquinazolinone‐based molecule W1B effectively suppresses glioblastoma by inhibiting IGF1R and EGFR. In high‐glucose microenvironments driving tumor resistance, W1B acts synergistically with the EGFR inhibitor dacomitinib. This combination safely blocks compensatory survival signaling in zebrafish xenograft models. Showcasing promising in

Identifying, Estimating and Testing Restricted Cointegrated Systems: An Overview [PDF]

open access: yes
The notion of cointegration has lead to a renewed interest in the identification and estimation of structural relations among economic time series, a field to which Henri Theil has made many pioneering contributions.

Oncogenic DMTF1β promotes cancer cell motility by regulating autophagy through ULK1 stabilization

open access: yesMolecular Oncology, EarlyView.
In the current study, we demonstrate that the oncogene DMTF1β regulates ULK1 stability by reducing its proteasomal degradation in cancer cells. This stabilization enables ULK1 to induce autophagy, which in turn facilitates cancer cell migration. Consequently, reduced DMTF1β levels lead to decreased autophagy and impaired cancer cell migration.
