T Cell Microenvironmental Impacts and Therapeutic Opportunities: Application to Human Testicular Germ Cell Tumors

Andrology, EarlyView.
ABSTRACT Testicular germ cell tumors (TGCT) are the leading malignancy in adolescent and young adult males, yet the immunological and cellular mechanisms governing their tumor microenvironment (TME) remain poorly understood. Here, we present a comprehensive review of TGCT pathobiology with a focus on the immune landscape, particularly the role of tumor‐

CCR4 Antagonist (C021) Administration Diminishes Hypersensitivity and Enhances the Analgesic Potency of Morphine and Buprenorphine in a Mouse Model of Neuropathic Pain

Frontiers in Immunology, 2020
Neuropathic pain is a chronic condition that remains a major clinical problem owing to high resistance to available therapy. Recent studies have indicated that chemokine signaling pathways are crucial in the development of painful neuropathy; however ...

scRNA‐Seq in Gastric Cancer Reveals Macrophage‐Derived C1q as a Diagnostic Marker

Cancer Science, EarlyView.
Single‐cell sequencing of GC analyzed the tumor microenvironment and discovered the C1QA+ TAMs subpopulation with immunosuppressive function. The role of C1q in the prognosis and diagnosis of GC was demonstrated through plasma and tumor tissue from the GC cohort.

Multivalent interactions with CCR4–NOT and PABPC1 determine mRNA repression efficiency by tristetraprolin

Nature Communications
Tristetraprolin family of proteins regulate mRNA stability by binding to specific AU-rich elements in transcripts. This binding promotes the shortening of the mRNA poly(A) tail, or deadenylation, initiating mRNA degradation.

Etude structurale du complexe CCR4-NOT

, 2015
MRNA turnover begins with deadenylation where in the poly(A) tail at the 3’ end of the mRNA is removed. Deadenylation is the rate-limiting step of the decay pathway.

Deadenylation of mRNA by the CCR4-NOT complex in Drosophila: molecular and developmental aspects

Frontiers in Genetics, 2014
Controlled shortening of the poly(A) tail of mRNAs is the first step in eukaryotic mRNA decay and can also be used for translational inactivation of mRNAs.

Primary Cutaneous Gamma‐Delta T‐Cell Lymphoma Complicating Long‐Standing Immunosuppressed Dermatomyositis

Journal of Cutaneous Pathology, EarlyView.
ABSTRACT Primary cutaneous gamma‐delta T‐cell lymphoma (PCGD‐TCL) is a rare cytotoxic lymphoma with key oncogenic drivers in the JAK/STAT pathway. Also primarily involving the subcutaneous adipose tissue, subcutaneous panniculitis‐like T‐cell lymphoma (SPTCL) is more frequently encountered in scenarios of autoimmune disorders.

Structural studies of the complex CCR4-NOT

, 2015
Le recyclage des ARN débute par un étape de déadenylation ou la queue poly (A) est enzymatiquement clivée. La deadenylation est l’étape limitante dans le processus de dégradation des ARN.

1‐Hydroxy‐xanthine derivatives inhibit the human Caf1 nuclease and Caf1‐containing nuclease complexes via Mg2+‐dependent binding

FEBS Open Bio, 2019
In eukaryotic cells, cytoplasmic mRNA is characterised by a 3′ poly(A) tail. The shortening and removal of poly(A) tails (deadenylation) by the Ccr4‐Not nuclease complex leads to reduced translational efficiency and RNA degradation.

Cutaneous lymphomas – an update

Histopathology, EarlyView.
Primary cutaneous lymphomas and lymphoproliferative disorders are defined by integrated clinical, histopathological, immunophenotypic and genetic features as diagnostic criteria also in the 5th edition of the WHO classification of haematolymphoid tumors.
