Posttranscriptional regulation of gene expression – adding another layer of complexity to the DNA damage response

Frontiers in Genetics, 2012
In response to DNA damage, cells activate a complex, kinase-based signaling network to arrest the cell cycle and allow time for DNA repair, or, if the extend of damage is beyond repair capacity, induce apoptosis.

Baicalein Sensitizes Radioresistant BT549 and MCF7‐R Breast Cancer Cells by Modulating Rac1 Signaling

Phytotherapy Research, EarlyView.
ABSTRACT Radioresistance remains a key barrier in breast cancer (BC) treatment. Baicalein, a flavonoid from Scutellaria baicalensis, has shown potential to enhance radiosensitivity. This study investigates its efficacy and mechanism in radioresistant BC models. Radioresistant BC cell models were established via fractionated irradiation and validated by

Response to DNA damage: why do we need to focus on protein phosphatases?

Frontiers in Oncology, 2013
Eukaryotic cells are continuously threatened by unavoidable errors during normal DNA replication or various sources of genotoxic stresses that cause DNA damage or stalled replication.

Regulation of protein kinase B (PKB/Akt) by DNA-dependent protein kinase (DNA-PK) under physiological conditions [PDF]

, 2010
The serine/threonine protein kinase B (PKB/Akt) is a downstream effector of phosphatidylinositol 3-kinase (PI3K) and a major regulator of a variety of cellular processes, including metabolism, transcription, survival, proliferation, and growth.

Chaetocin Induces Ferroptosis in Cisplatin‐Resistant Ovarian Cancer Cells Through Neddylation‐Mediated TFRC Upregulation

Phytotherapy Research, EarlyView.
Chaetocin induces ferroptosis in cisplatin‐resistant ovarian cancer cells through neddylation‐mediated TFRC upregulation. ABSTRACT Ovarian cancer (OV) is a highly lethal gynecological tumor, often developing platinum chemotherapy resistance and treatment failure.

Drosophila RecQ4 Is Directly Involved in Both DNA Replication and the Response to UV Damage in S2 Cells. [PDF]

, 2012
The RecQ4 protein shows homology to both the S.cerevisiae DNA replication protein Sld2 and the DNA repair related RecQ helicases. Experimental data also suggest replication and repair functions for RecQ4, but the precise details of its involvement remain

NTAQ1 Promotes Hepatocellular Carcinoma Growth by Facilitating the Protein Degradation of the Tumor Suppressor PRDM2

Cancer Science, EarlyView.
Copy number variation analysis in The Cancer Genome Atlas identified NTAQ1 as a potential driver of HCC progression. NTAQ1 accelerates tumor growth by promoting the degradation of the tumor suppressor protein PRDM2, thereby impairing DNA repair and suppressing apoptosis. These findings indicate that NTAQ1 could be a valuable target for the treatment of

The DNA/RNA Helicase SETX Maintains R‐Loop Homeostasis to Promote Chemoresistance in Ovarian Cancer

Cancer Science, EarlyView.
SETX maintains R‐loop homeostasis by resolving excessive R‐loops, thereby promoting tumor initiation and chemoresistance. Deficiency of SETX leads to accumulation of unsolved pathological R‐loops, resulting in irreparable DNA damage and ultimately leading to tumor suppression and chemosensitivity.

Zeocin-induced DNA damage response in barley and its dependence on ATR

Scientific Reports
DNA damage response (DDR) is an essential mechanism by which living organisms maintain their genomic stability. In plants, DDR is important also for normal growth and yield.

Methodological Landscape of DNA Damage Response Detection: From Conventional Assays to Future Innovations

Current Issues in Molecular Biology
All living organisms possess a DNA damage response (DDR) that is important for genetic evolution. Cells have developed comprehensive mechanisms for addressing DNA damage, collectively called the DNA damage response and repair.
