Change in Nutritional Status Modulates the Abundance of Critical Pre-initiation Intermediate Complexes During Translation Initiation \u3cem\u3ein Vivo\u3c/em\u3e [PDF]

open access: yes, 2007
In eukaryotic translation initiation, eIF2∙GTP–Met-tRNAiMet ternary complex (TC) interacts with eIF3–eIF1–eIF5 complex to form the multifactor complex (MFC), while eIF2∙GDP associates with eIF2B for guanine nucleotide exchange.

COMP–PMEPA1 axis promotes epithelial‐to‐mesenchymal transition in breast cancer cells

open access: yesMolecular Oncology, EarlyView.
This study reveals that cartilage oligomeric matrix protein (COMP) promotes epithelial‐to‐mesenchymal transition (EMT) in breast cancer. We identify PMEPA1 (protein TMEPAI) as a novel COMP‐binding partner that mediates EMT via binding to the TSP domains of COMP, establishing the COMP–PMEPA1 axis as a key EMT driver in breast cancer.

Generation of a Monoclonal Antibody Specifically Reacting with Neuron-specific TATA-Box Binding Protein-Associated Factor 1 (N-TAF1)

open access: yesAntibodies, 2012
TATA-box binding protein-associated factor 1 (TAF1), the largest subunit of the transcription factor IID complex, plays an important role in the RNA polymerase II-mediated gene transcription pathway regulating the transcription of a large number of genes

Lysine acetyltransferase 5 in EGFR mutated non-small cell lung cancer [PDF]

open access: yes, 2018
Histone modifications are crucial in activities such as transcriptional activation, gene silencing, and epigenetic cellular memory. In particular, lysine acetylation via lysine (K) acetyltransferases (KATs) has been implicated in cancer development ...

Tyrosine dephosphorylation of H2AX modulates apoptosis and survival decisions. [PDF]

open access: yes, 2009
Life and death fate decisions allow cells to avoid massive apoptotic death in response to genotoxic stress. Although the regulatory mechanisms and signalling pathways controlling DNA repair and apoptosis are well characterized, the precise molecular ...

DDX3X induces mesenchymal transition of endothelial cells by disrupting BMPR2 signaling

open access: yesFEBS Open Bio, EarlyView.
Elevated DDX3X expression led to downregulation of BMPR2, a key regulator of endothelial homeostasis and function. Our co‐immunoprecipitation assays further demonstrated a molecular interaction between DDX3X and BMPR2. Notably, DDX3X promoted lysosomal degradation of BMPR2, thereby impairing its downstream signaling and facilitating endothelial‐to ...

Preactivation Crosslinking—An Efficient Method for the Oriented Immobilization of Antibodies

open access: yesMethods and Protocols, 2019
Crosslinking of proteins for their irreversible immobilization on surfaces is a proven and popular method. However, many protocols lead to random orientation and the formation of undefined or even inactive by-products.

Down‐regulation of Shh in the hair follicles of mice during chemotherapy‐induced hair loss is mediated by the JAK/STAT1 signaling pathway

open access: yesFEBS Open Bio, EarlyView.
We found that during chemotherapy‐induced alopecia (CIA), Sonic hedgehog (Shh) expression significantly decreased in hair follicle Shh+ cells, whereas the Janus‐activated kinase/signal transducer and activator of transcription 1 (JAK/STAT1) signaling pathway was markedly activated.

Severe finger necrosis in antisynthetase syndrome with positive anti‐OJ antibodies

open access: yesClinical Case Reports
Key Clinical Message In a patient with anti‐aminoacyl tRNA synthetase antibody and anti‐OJ antibody syndrome, interventions likes warming, prostaglandins, and antiplatelets failed. However, prednisolone pulse treatment rapidly halted disease progression.

CIB1 protects against MPTP-induced neurotoxicity through inhibiting ASK1. [PDF]

open access: yes, 2017
Calcium and integrin binding protein 1 (CIB1) is a calcium-binding protein that was initially identified as a binding partner of platelet integrin αIIb. Although CIB1 has been shown to interact with multiple proteins, its biological function in the brain
