Localisation of the Ki-67 antigen within the nucleolus: Evidence for a fibrillarin-deficient region of the dense fibrillar component [PDF]

, 1996
The Ki-67 antigen is detected in proliferating cells in all phases of the cell division cycle. Throughout most of interphase, the Ki-67 antigen is localised within the nucleolus.

Resistance‐exercise‐induced stress intervenes in TGF‐β signaling by cooperatively downregulating nuclear αB‐crystallin and SMAD4 in human skeletal muscle fibers

The FEBS Journal, EarlyView.
Alpha‐crystallin B chain (CRYAB) has been reported to stabilize mothers against decapentaplegic homolog 4 (SMAD4) in transforming growth factor‐β (TGF‐β) signaling, enabling target gene transcription. We show nuclear CRYAB–SMAD4 interaction for the first time in human skeletal muscle fibers and its regulation by exercise.

Abnormal A-type lamin organization in a human lung carcinoma cell line.

European journal of cell biology, 1995
We have studied the expression of lamins A and C (A-type lamins) in a lung carcinoma cell line using type-specific monoclonal antibodies. Using immunofluorescence and immunoblotting studies it was noted that several irregularities in lamin expression exist in the cell line GLC-A1, derived from an adenocarcinoma.

Disruption of iron metabolism resulting from Dmt1/Slc11a2 deficiency compromises Notch protein degradation and transcriptional activation

The FEBS Journal, EarlyView.
Divalent metal transporter 1 (Dmt1) maintains iron homeostasis and lysosomal proteostasis required for physiological Notch receptor–ligand signaling. Dmt1 loss lowers iron storage capacity (ferritin), increasing intracellular Fe2+, driving ROS and lipid peroxidation, and leading to lysosomal/mitochondrial dysfunction.

Unveiling Propriety, Validity and Consensus: A Multi‐level Examination of Legitimacy Following the Global Financial Crisis

Journal of Management Studies, EarlyView.
Abstract Previous work on legitimacy has conceptualized its multi‐level nature, encompassing individual‐level propriety and collective‐level validity. Recently, scholars have introduced the construct of consensus, the degree to which evaluators agree in terms of their propriety beliefs.

Leave It to Me: Overconfident CEOs’ Lower Propensity to Delegate Acquisition Responsibility

Journal of Management Studies, EarlyView.
Abstract Overconfident CEOs have been shown to lead their firms to achieve different outcomes, but the literature has only a limited understanding why this is the case. In this paper, we focus on whether overconfident CEOs run their firms differently, focusing on a key internal interaction: CEOs' choices regarding whether to delegate to other ...

Parenthood and CEO Responses to Media Criticism on Pay

Journal of Management Studies, EarlyView.
Abstract Research on media coverage of controversial corporate practices typically suggests firms respond instrumentally to mitigate stakeholder reactions. However, we argue that CEOs' moral concerns can sometimes override strategic considerations, because media criticism may expose them to scrutiny from personally valued audiences – for instance ...

Nuclear-lamin-guided plastic positioning and folding of the human genome

Cell Reports
Summary: The human genome exhibits a highly ordered hierarchical architecture, yet the mechanisms governing its large-scale organization remain poorly understood.

A Multifunctional β‐Defensin‐3 Mimetic Peptide Modulates Host–Biofilm Interactions and Reduces Bone Loss in Periodontitis

Journal of Periodontal Research, EarlyView.
BDMP, a peptide that can penetrate cells and tissues, offering antimicrobial and anti‐inflammatory effects, has been identified as a potential new therapy for periodontitis. ABSTRACT Aim This study evaluated the potential of a beta‐defensin‐3 mimetic peptide (BDMP), a synthetic cell‐penetrating peptide with antimicrobial and immunomodulatory properties,

PWO proteins are associated with PRC2 since their emergence in vascular plants

New Phytologist, EarlyView.
Summary The Polycomb repressive complex 2 (PRC2), a conserved histone methyltransferase complex, plays a central role in transcriptional silencing across eukaryotes. Here, we investigate the evolution of PWWP‐DOMAIN INTERACTORS OF POLYCOMBS (PWOs), which interact with PRC2, and examine the conservation of the PWOs‐PRC2 interaction across plant ...
