Exploring the role of cGAS-STING-mediated inflammation in age-associated neurodegeneration and antitumor immunity

Natasha Ella Samson

Inflammation stands as a dynamic and intricate biological process, promoting vital defence mechanisms against harmful stimuli, including infections and injuries, to drive pathogen clearance and healing. On one hand, these responses can manifest acutely and ...

Single-cell analysis of the interactions between Mycobacterium tuberculosis and macrophages

Ophélie Rutschmann

Mycobacterium Tuberculosis is a highly effective pathogen infecting nearly a third of the world's population. An M. tuberculosis infection starts when droplets containing bacteria enter an individual's lungs. The first host cells to contact the bacteria ar ...

Investigating the effect of inflammation on the progression of B-cell lymphoma dissemination in the sentinel lymph node

Daniel Molina Romero

Lymphomas are a group of heterogeneous blood cancers that arise from lymphocytes. The two primary clinical classifications of lymphomas are Hodgkin's lymphoma (HL), and non-Hodgkin's lymphoma (NHL). In particular, B-cell lymphoma refers to the malignancies ...

KRAB zinc finger proteins link heterochromatin maintenance to replicative stress and inflammation in diffuse large B-cell lymphoma

Filipe Amândio Brandão Sanches Vong Martins

Genomic instability enhances cancer progression by favoring clonal diversity, yet uncontrolled replicative stress can lead to mitotic catastrophe and inflammatory responses promoting immune rejection. KRAB-containing zinc finger proteins (KZFPs) are epigen ...

Multitarget-Directed Gallium(III) Tris(acyl-pyrazolonate) Complexes Induce Ferroptosis in Cancer Cells via Dysregulation of Cell Redox Homeostasis and Inhibition of the Mevalonate Pathway

Farzaneh Fadaei Tirani

A series of Ga(Q(n))(3) coordination compounds have been synthesized, where HQ(n) is 1-phenyl-3-methyl-4-RC(=O)-pyrazolo-5-one. The complexes have been characterized through analytical data, NMR and IR spectroscopy, ESI mass spectrometry, elemental analysi ...

Caspase-9-mediated cleavage of vimentin attenuates the aggressiveness of leukemic NB4 cells

Saeed Mohammadi, Cyrus Kazemiraad

Vimentin is a main type 3 intermediate filament protein. It seems that abnormal expression of vimentin is contributed to the appearance of the aggressive feature of cancer cells. So that it has been reported that malignancy and epithelial-mesenchymal trans ...

Real-time monitoring of single-cell secretion with a high-throughput nanoplasmonic microarray

Hatice Altug, Xiaokang Li, Yen-Cheng Liu, Eduardo Romero Arvelo, Saeid Ansaryan

Proteins secreted by cells play significant roles in mediating many physiological, developmental, and pathological processes due to their functions in intra/intercellular communication and signaling. Conventional end-point methods are insufficient for unde ...

Colon tumour cell death causes mTOR dependence by paracrine P2X4 stimulation

Andrea Ablasser

Solid cancers exhibit a dynamic balance between cell death and proliferation ensuring continuous tumour maintenance and growth(1,2). Increasing evidence links enhanced cancer cell apoptosis to paracrine activation of cells in the tumour microenvironment in ...

NRF2 Activation Confers Resistance to eIF4A Inhibitors in Cancer Therapy

Linlin Cao

Inhibition of the eIF4A RNA helicase with silvestrol and related compounds is emerging as a powerful anti-cancer strategy. We find that a synthetic silvestrol analogue (CR-1-31 B) has nanomolar activity across many cancer cell lines. It is especially activ ...

Genomic studies indicate a novel combination therapy for follicular lymphoma COMMENT

Elisa Oricchio

Follicular lymphoma (FL) is an incurable form of B-cell lymphoma. Genomic alterations that inactivate RB signaling are surprisingly common in indolent FL. We show that FLs that are positive for phosphorylated RB respond to dual CDK4/BCL2 inhibition. Our re ...
