Hirschmanniella maritima n. sp. (Nematoda: Pratylenchidae) – a New Nematode Species Parasitizing Baltic Plants in Poland

Journal of Nematology
Hirschmanniella maritima n. sp. was recovered from the roots of Potamogeton perfoliatus L. plants collected in several locations along the Baltic coast (from the Puck Bay to the Vistula Lagoon) in Poland. H. maritima n. sp. is characterized by a long (L =

Ribosomal protein S3: A multifunctional target of attaching/effacing bacterial pathogens

Frontiers in Cellular and Infection Microbiology, 2011
The extraribosomal functions of ribosomal proteins have drawn significant recent attention. Ribosomal Protein S3 (RPS3), a component of the eukaryotic 40S ribosomal subunit, is a multifunctional protein that regulates DNA repair, apoptosis, and the ...

Tumor‐Derived Alpha‐1 Antitrypsin Promotes Liver Metastasis of Colorectal Cancer Through the Neutrophil Extracellular Traps–CCDC25 Pathway

Advanced Science, EarlyView.
ABSTRACT Liver metastasis is a leading cause of mortality in colorectal cancer (CRC), where the inflammatory tumor microenvironment, specifically neutrophil infiltration, significantly promotes metastatic colonization. This study reveals a pro‐metastatic role for alpha‐1 antitrypsin (A1AT) in CRC liver metastasis via a dual mechanism involving ...

RNA polymerase I transcription and pre-rRNA processing are linked by specific SSU processome components [PDF]

, 2004
Sequential events in macromolecular biosynthesis are often elegantly coordinated. The small ribosomal subunit (SSU) processome is a large ribonucleoprotein (RNP) required for processing of precursors to the small subunit RNA, the 18S, of the ribosome. We

Molecular and morphological characterization of Avenae-group cyst nematodes (Heteroderidae) from Greece

Journal of Nematology
Cyst nematodes of the genus Heterodera comprise 87 nominal species of economically important plant parasites, with the Avenae-group one of the largest, consisting of 12 species. Samplings for cyst nematode studies were carried out from multiple locations

Tumor‐Derived LAMB3 Drives Immunosuppressive LRRC15+ Fibroblast Formation During Pancreatic Ductal Adenocarcinoma Development

Advanced Science, EarlyView.
A single‐cell atlas of pancreatic ductal adenocarcinoma development reveals progressive ductal‐fibroblast‐immune crosstalk. Tumor‐derived LAMB3 drives the formation of immunosuppressive LRRC15+ fibroblasts through the ITGB1/FAK/MAPK/FOSL2 signaling. Glycolytic reprogramming upregulates LAMB3 and correlates with LRRC15+ fibroblast enrichment.

Integration of Spatiotemporal Multi‐Omics in Peach Fruit Unravels a Metabolic Niche and the Genetic Basis of Trichome‐Mediated Stress Adaptation

Advanced Science, EarlyView.
This study constructed the first spatiotemporal multi‐omics map of peach fruit and discovered a key candidate gene that synergistically regulates trichome development and drought tolerance through the jasmonic acid signaling pathway, providing insights into the coupling mechanism between development and stress resistance.

Morphological and molecular identification of filamentous fungi isolated from cosmetic powders

Brazilian Archives of Biology and Technology, 2012
Seven fungi were isolated from 50 samples of cosmetic powders. Morphological analyses and ribosomal DNA Internal Transcribed Spacers sequencing were performed which allowed the discrimination of the isolated fungi as Aspergillus fumigatus, Penicillium sp.

Balancing copy number in ribosomal DNA [PDF]

Proceedings of the National Academy of Sciences, 2015
Ecologists recognize the balance of nature as a complex system that arises from interacting and connected parts; disturbing the balance can affect other species in nonlinear and dynamic ways. Like ecosystems, the cell and genome are extensively connected by an abundance of molecular interactions. Upsetting the molecular balance, through changes in gene

Cuproptosis and Mitophagy Mediated by the THUMPD1/IGF2R‐Dependent Suppression of AKT and Activation of AMPK Signaling Suppress Lung Adenocarcinoma Progression

Advanced Science, EarlyView.
THUMPD1 drives a tumor‐suppressive signaling cascade in lung adenocarcinoma by promoting IGF2R expression. IGF2R associates with PPP2R1A to suppress AKT and activate AMPK, leading to SLC31A1 upregulation and copper accumulation. Elevated copper disrupts mitochondrial metabolism and induces excessive mitophagy, thereby restraining tumor growth and ...
