Regulation of Fas mediated apoptosis by CD44 [PDF]

open access: yes, 2005
Over the last decade, apoptosis has grown from an obscure process to a complex and interesting scientific field, and many players have been identified.

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

Rab44 isoforms similarly promote lysosomal exocytosis, but exhibit differential localization in mast cells

open access: yesFEBS Open Bio, 2021
Rab44 is a large Rab GTPase containing a Rab GTPase domain and some additional N‐terminal domains. We recently used Rab44‐deficient mice to demonstrate that Rab44 regulates granule exocytosis in mast cells and IgE‐mediated anaphylaxis.

Structural and biological characterization of two crotamine isoforms IV-2 and IV-3 isolated from the Crotalus durissus cumanensis venom

open access: yes, 2015
In this work, we isolated the two new crotamine isoforms from the Crotalus durissus cumanensis rattlesnake venom and its 'in vitro' neurotoxic, myotoxic and lethality (DL50) intracerebroventricular (i.c.v.) effects were characterized. These proteins were

Entrapment of viral capsids in nuclear PML cages is an intrinsic antiviral host defense against varicella-zoster virus. [PDF]

open access: yes, 2011
The herpesviruses, like most other DNA viruses, replicate in the host cell nucleus. Subnuclear domains known as promyelocytic leukemia protein nuclear bodies (PML-NBs), or ND10 bodies, have been implicated in restricting early herpesviral gene expression.

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.

Iron homeostasis disruption and lipid peroxidation in skeletal muscle during short‐term immobilization

open access: yesFEBS Open Bio, EarlyView.
14‐day casting‐induced immobilization reduced gastrocnemius muscle mass and increased non‐heme iron and ferritin heavy chain levels. Despite iron accumulation, transferrin receptor 1 and iron regulatory protein 2 were paradoxically upregulated. Lipid peroxidation was elevated without compensatory antioxidant responses.

Δ133p53α and Δ160p53α isoforms of the tumor suppressor protein p53 exert dominant-negative effect primarily by co-aggregation

open access: yeseLife
p53 is a tumor suppressor protein with multiple isoforms with shared or specific functions. However, two of its isoforms, Δ133p53α and Δ160p53α, with large N-terminal deletions, can cause cancer.

Systemic dysregulation of apolipoproteins in amyotrophic lateral sclerosis serum

open access: yesFEBS Open Bio, EarlyView.
Amyotrophic lateral sclerosis (ALS) is a fatal disease that damages motor neurons. This study found that people with ALS show significant changes in blood fats and the proteins that carry them. Several apolipoproteins were higher, lipid balances were altered, and normal protein–lipid relationships were disrupted.

Drosophila HP1c is regulated by an auto-regulatory feedback loop through its binding partner Woc [PDF]

open access: yes, 2009
HP1 is a major component of chromatin and regulates gene expression through its binding to methylated histone H3. Most eukaryotes express at least three isoforms of HP1 with similar domain architecture.
