Metastatic hepatocellular carcinoma (HC) is a serious health concern. The stemness of cancer stem cells (CSCs) is a key driver for HC tumorigenesis, apoptotic resistance, and metastasis, and functional mitochondria are critical for its maintenance. Cuproptosis is Cu-dependent non-apoptotic pathway (mitochondrial dysfunction) via inactivating mitochondrial enzymes (pyruvate dehydrogenase "PDH" and succinate dehydrogenase "SDH").

Bioprocess Development Department, Genetic Engineering and Biotechnology Research Institute (GEBRI), City of Scientific Research and Technological Applications (SRTA-City), New Burg El-Arab City, Universities and Research Institutes Zone, Alexandria, 21934, Egypt.

The goal of the current work was to optimize the growth parameters needed to manufacture agarase enzyme from a non-marine PI strain of Bacillus subtilis on an agar-based medium. Using Plackett-Burman design (PBD), nine process parameters were evaluated, and agar, peptone, and yeast-extract were identified as the most significant independent factors influencing agarase production with confidence levels more than 90%. To evaluate the optimal concentrations of the indicated process parameters on agarase production, the Box-Behnken design (BBD) was applied.

Article Synopsis
  • The Gadd45 gene, particularly Gadd45A, plays a crucial role in CNS functions and is linked to neurodegenerative diseases like Alzheimer's disease (AD).
  • The study revealed that deleting Gadd45A disrupts autophagy regulation by influencing Cdkn1A expression, leading to cognitive impairments and neuroinflammation in a mouse model.
  • Results showed that Gadd45A knockout mice exhibited memory deficits, increased Tau hyperphosphorylation, higher levels of pro-inflammatory cytokines, and lower markers of autophagy, highlighting its potential role in AD pathology.
