The Transcription Factor FgSge1 Harnesses the SAGA Complex to Activate Mycotoxin Biosynthesis and Fungal Virulence

Advanced Science, EarlyView.
This study reveals the molecular mechanism by which the transcription factor FgSge1 regulates mycotoxin biosynthesis and virulence in Fusarium graminearum. FgSge1 binds to the TAARGTTT cis‐element, enabling self‐activation. It recruits the SAGA complex, promotes histone acetylation, and facilitates jet‐like chromatin remodeling, thereby activating ...

Somatic Kitl promotes mTOR to facilitate prophase I of meiosis in female embryonic gonads

Cell Death and Disease
Homologous synapsis and recombination are the central events that take place in the prophase I of meiosis. Signaling that promotes the germ cell differentiation and prophase I remains elusive.

The MRN complex is transcriptionally regulated by MYCN during neural cell proliferation to control replication stress [PDF]

, 2015
The MRE11/RAD50/NBS1 (MRN) complex is a major sensor of DNA double strand breaks, whose role in controlling faithful DNA replication and preventing replication stress is also emerging. Inactivation of the MRN complex invariably leads to developmental and/

A theory for the tissue specificity of BRCA1/2 related and other hereditary cancers [PDF]

, 2010
Women who inherit a defective BRCA1 or BRCA2 gene have risks for breast and ovarian cancer that are so high and seem so selective that many mutation carriers choose to have prophylactic surgery. There has been much conjecture to explain such apparently

Reduced Maintenance DNA Methylation Thresholds Enable Sensitive Reporter Assays for UHRF1 and DNMT1 Inhibition

Advanced Science, EarlyView.
The authors engineer colorectal cancer cells with reduced redundancy of UHRF1 and DNMT1, key DNA methylation maintenance factors, lowering the maintenance threshold and sensitizing cells to inhibition. They develop reporter assays driven by endogenous tumor‐suppressor gene promoters with enhanced sensitivity and dynamic range to demethylating drugs ...

Inhibition of SIRT7 Overcomes Radioresistance in Pancreatic Neuroendocrine Tumors by Reactivating MEN1 Expression

Advanced Science, EarlyView.
Pancreatic neuroendocrine tumors frequently silence MEN1 through epigenetic mechanisms. Here, SIRT7 recruits DNMT1 to the MEN1 promoter, drives hypermethylation, and enhances DNA repair. Inhibiting SIRT7 restores MEN1, reduces MRN complex abundance, impairs double‐strand break repair, and sensitizes PanNET models to radiation, supporting SIRT7 as a ...

Icariin Enhances the Enzymatic Activity of N‐acetylgalactosaminidase to Augment Akkermansia Abundance in Gut Microbiota for Improved PD‐1 Blockade Efficacy in Tumor Suppression

Advanced Science, EarlyView.
Icariin promoted the growth of Akk by enhancing the activity of N‐acetylgalactosaminidase (Amuc_0920), which enhanced mucin utilization and provided a favorable nutrient environment for bacterial growth. This icariin‐mediated enrichment of Akk further reshaped the tumor microenvironment and promoted CD8+ T cell infiltration, ultimately synergizing with

Genetic Control of Tissue Remodeling by a Non‐Coding SNP in ITGA8 Explains Carotenoid‐Based Color Polymorphism in Marine Mollusks

Advanced Science, EarlyView.
In this study, the orange‐muscle giant abalone (Haliotis gigantea) is used as a model to identify a non‐coding SNP that disrupts the interaction between ITGA8 pre‐mRNA and the splicing factor ILF2, leading to altered ITGA8 splicing. These splicing changes promote carotenoid accumulation in abalone muscle through the regulation of tissue remodeling ...

Gene expression signature for predicting homologous recombination deficiency in triple-negative breast cancer

npj Breast Cancer
Triple-negative breast cancers (TNBCs) are a subset of breast cancers that have remained difficult to treat. A proportion of TNBCs arising in non-carriers of BRCA pathogenic variants have genomic features that are similar to BRCA carriers and may also ...
