AI Article Synopsis
- * This study focused on the relationship between NDRG1 expression and the progression of glioblastoma (GB), analyzing tumor samples from 41 patients through immunostaining.
- * Results showed that higher NDRG1 expression was linked to increased tumor cell proliferation and lower survival rates, suggesting that elevated NDRG1 indicates poorer prognosis for GB patients.
Article Abstract
N-myc downstream regulated gene 1 (NDRG1) is a member of the NDRG family, of which four members (NDRG1, NDRG2, NDRG3, and NDRG4) have been identified. NDRG1 is repressed by c-MYC and N-MYC proto-oncogenes. NDRG1 is translated into a 43 kDa protein that is associated with the regulation of cellular stress responses, proliferation, and differentiation. In this study, we aimed to clarify the relationship between progression of glioblastoma (GB) IDH-wildtype and NDRG1 expression in tumor cells. We assessed the expression of NDRG1 in 41 GBs using immunostaining and evaluated its prognostic significance. NDRG1 expression by GBs was evaluated using Histoscore, which showed high and low scores in 23 and 18 cases, respectively. NDRG1-positive cells were strongly expressed in Ki-67 labeled proliferating tumor cells and CD105 positive proliferating microvessels around the area of palisading necrosis. Statistical analyses showed lower survival rates in the high-score group than the low-score group (P < 0.01). This study indicated that overexpression of NDRG1 by GB reflects tumor angiogenesis and poor patient prognosis.

N-myc downstream-regulated gene 1 (NDRG1) is a member of the NDRG family of intracellular proteins and plays a central role in a wide range of biological processes including stress response, differentiation, and metabolism. The overexpression of NDRG1 is an indicator of poor prognosis in various types of cancer. Here, we found that NDRG1 is an independent prognostic marker of poor outcome in breast cancer (BC).

Objective: To study the features of protein expression of gene in primary breast cancer (BC) and to identify its relationship with regional metastasis.
Material And Methods: The study included 358 cases of primary BC stages I-III without neoadjuvant chemotherapy with an assessment of a number of clinical, morphological and immunohistochemical parameters of the tumor, including NDRG1 protein expression status and its expression level.
Results: In two study groups with and without metastatic lymph node involvement, a statistically significant relationship was found between NDRG1 expression and histological type of BC, tumor grade, estrogen receptors expression, progesterone receptors expression, HER2 status and index Ki-67 (tumor cell proliferative activity).

Article Synopsis
- NDRG1 is a protein linked to angiogenesis and was studied for its expression in endometrial endometrioid carcinoma (EEC) patients.
- High levels of NDRG1 expression were associated with worse clinical outcomes, including advanced cancer stage, poor tumor differentiation, and lymph node metastasis.
- The findings indicate that elevated NDRG1 expression signifies increased angiogenesis and poorer survival rates for women with EEC.

Protein turnover is crucial for cell survival, and the impairment of proteostasis leads to cell death. Aging is associated with a decline in proteostasis, as the progressive accumulation of damaged proteins is a hallmark of age-related disorders such as neurodegenerative diseases, including amyotrophic lateral sclerosis (ALS). We previously discovered that the declining function of the ubiquitin-proteasome system (UPS) in motor neurons contributes to sporadic ALS pathologies, such as progressive motor neuron loss, protein accumulation, and glial activation.
