Nuclear rupture at sites of high curvature compromises retention of DNA repair factors. [PDF]

, 2018
The nucleus is physically linked to the cytoskeleton, adhesions, and extracellular matrix-all of which sustain forces, but their relationships to DNA damage are obscure. We show that nuclear rupture with cytoplasmic mislocalization of multiple DNA repair

Structural mechanism of cGAS inhibition by the nucleosome

Nature, 2020
The DNA sensor cyclic GMP-AMP synthase (cGAS) initiates innate immune responses following microbial infection, cellular stress and cancer1. Upon activation by double-stranded DNA, cytosolic cGAS produces 2'3' cGMP-AMP, which triggers the induction of inflammatory cytokines and type I interferons 2-7.

cGAS-STING pathway in cancer biotherapy [PDF]

Molecular Cancer, 2020
AbstractThe activation of the cGAS-STING pathway has tremendous potential to improve anti-tumor immunity by generating type I interferons. In recent decades, we have witnessed that producing dsDNA upon various stimuli is an initiative factor, triggering the cGAS-SING pathway for a defensive host. The understanding of both intracellular cascade reaction

cGAS: action in the nucleus

Frontiers in Immunology
As a canonical cytoplasmic DNA sensor, cyclic GMP-AMP synthase (cGAS) plays a key role in innate immunity. In recent years, a growing number of studies have shown that cGAS can also be located in the nucleus and plays new functions such as regulating DNA damage repair, nuclear membrane repair, chromosome fusion, DNA replication, angiogenesis and other ...

Chromogranin A (CgA) in adrenal tumours

Endokrynologia Polska, 2013
Adrenal tumours can produce specific hormones and cause characteristic symptoms. The majority of adrenal incidentalomas are clinically silent, but some may be malignant or pose other potential threats to life. Chromogranin A (CgA) is the main, nonspecific marker of neuroendocrine tumours (NET).

MET and NF2 alterations confer primary and early resistance to first‐line alectinib treatment in ALK‐positive non‐small‐cell lung cancer

Molecular Oncology, EarlyView.
Alectinib resistance in ALK+ NSCLC depends on treatment sequence and EML4‐ALK variants. Variant 1 exhibited off‐target resistance after first‐line treatment, while variant 3 and later lines favored on‐target mutations. Early resistance involved off‐target alterations, like MET and NF2, while on‐target mutations emerged with prolonged therapy.

CINs of the cytoplasm: dissecting dsRNA signaling in chromosomal instability

Molecular Oncology, EarlyView.
Micronuclei, formed during cell division in chromosomal instability settings, rupture and lead to the accumulation of immunogenic double‐stranded RNA in the cytoplasm, activating MAVS‐dependent interferon signaling and innate antitumor immunity.

The Regulation of Trace Metal Elements in Cancer Ferroptosis

Advanced Biology, EarlyView.
The induction of ferroptosis inhibits tumor growth, enhances anticancer efficacy, and overcomes drug resistance. Recent evidence shows nonferrous metal elements play a role in ferroptosis. This review focuses on how trace metals regulate ferroptosis processes like iron accumulation, lipid peroxidation, and antioxidant defense.
