SETDB1 knockdown boosts recombinant protein in CHO cells via epigenetic transcriptional silencing.

Chinese hamster ovary (CHO) cells serve as the predominant mammalian expression system for recombinant protein production. However, clonal heterogeneity and instability in recombinant protein expression remain significant challenges. SET domain bifurcated histone lysine methyltransferase 1 (SETDB1) catalyzes histone 3 lysine 9 trimethylation (H3K9me3), a critical epigenetic modification regulating gene expression.

Effect of Apoptosis and Autophagy on Recombinant Protein Expression in Chinese Hamster Ovary Cells.

Chinese hamster ovary (CHO) cells serve as a cornerstone platform for producing diverse therapeutic recombinant proteins, including monoclonal antibodies, vaccines, and hormones. Apoptosis and autophagy emerge as critical biological factors that directly impair cell proliferation and limit recombinant protein production. These cellular processes diminish CHO cell viability and reduce culture density, ultimately compromising protein yield and product quality.

We enrolled 161 glaucoma patients and 181 healthy controls. Serum Alb and LYMPH% were measured using standard blood biochemistry and routine tests, and LAP was calculated accordingly.

Helicobacter pylori infection might be a protective factor against Parkinson's disease.

The gastrointestinal tract is not only an important component of the digestive system but also a crucial part of the body's immune system. Numerous studies have reported that gastrointestinal immunity plays a critical role in many extraintestinal diseases, including neurodegenerative disorders. However, the relationship between gastric mucosal immunity and neurodegenerative diseases, such as Parkinson's disease(PD), remains underexplored.

Overexpression of Tgm2 in Chinese Hamster Ovary Cells Enhances Recombinant Monoclonal Antibody Expression and Promotes Cell Proliferation through Reduction of Apoptosis.

Chinese hamster ovary (CHO) cells are the preferred host system for producing protein-based (antibody) therapeutics. However, recombinant CHO cells undergo substantial apoptosis during prolonged cultivation, impairing cell growth and ultimately compromising product yield and quality. Transglutaminase 2 (Tgm2), which mediates post-translational modifications of substrate proteins, regulates critical biological processes including cellular differentiation, apoptosis, cell cycle progression, and extracellular matrix assembly.

The comparative genomic analysis provides insight into the divergent inhibitory activity metabolites in pathogen-driven three Pseudomonas palleroniana strains against primary pathogens of Pseudostellaria heterophylla.

Pseudostellaria heterophylla (Miq.) Pax ex Pax et Hoffm. is a member of the Caryophyllaceae family, in which dried tuberous root is the well-known traditional Chinese medicine (TCM) and a widespread food ingredient in Asia.

MAT2A Knockdown Enhances Recombinant Protein Expression in Transgenic CHO Cells Through Regulation of Cell Cycle.

Chinese hamster ovary (CHO) cells represent the most widely utilized host system for industrial production of high-quality recombinant protein therapeutics. Novel CHO cell line development is achieved through genetic and cellular engineering approaches, effectively addressing limitations such as clonal variation and productivity loss during culture. Previous studies have established that MAT2A inhibition in tumor cells promotes expression of the cyclin-dependent kinase inhibitor p21, inducing antitumor activity.

Omentin-1, a Protective Adipokine for Irritable Bowel Syndrome.

Introduction: Irritable bowel syndrome (IBS) is characterized by patients' high level of suffering. There is increasing evidence for involvement of the immune system in this disease.

SEPT5 overexpression predicts poor prognosis and promotes progression through feedback regulation of HIF-1α in clear cell renal cell carcinoma.

Clear cell renal cell carcinoma (ccRCC), a predominant subtype of renal cell carcinoma, significantly contributes to the heightened morbidity and mortality in individuals diagnosed with urologic tumors. The challenges posed by high malignancy at the initial diagnosis of ccRCC, therapeutic resistance, and unfavorable patient prognosis remain largely unresolved. Our findings indicate that SEPT5 is upregulated in ccRCC and this upregulation is associated with an adverse prognosis for ccRCC patients.
