Molecular and cellular insights into the role of SND1 in lipid metabolism

Publication date: Available online 21 January 2020Source: Biochimica et Biophysica Acta (BBA) - Molecular and Cell Biology of LipidsAuthor(s): Hiart Navarro-Imaz, Begoña Ochoa, Itsaso García-Arcos, María José Martínez, Yolanda Chico, Olatz Fresnedo, Yuri RuedaAbstractStaphylococcal nuclease and Tudor domain containing 1 (SND1) is an evolutionarily conserved protein present in eukaryotic cells from protozoa to mammals. SND1 has gained importance because it is overexpressed in aggressive cancer cells and diverse primary tumors. Indeed, it is regarded as a marker of cancer malignity. A broad range of molecular functions and the participation in many cellular processes have been attributed to SND1, mostly related to the regulation of gene expression. An increasing body of evidence points to a relevant relationship between SND1 and lipid metabolism. In this review, we summarize the knowledge about SND1 and its molecular and functional relationship with lipid metabolism. We highlight that SND1 plays a direct role in the regulation of cholesterol metabolism by affecting the activation of sterol response element-binding protein 2 (SREBP2) and we propose that that might have implications in the response of lipid homeostasis to stress situations.

In this study, fluorescence emission spectroscopy and mass spectrometry (MALDI-TOF) were employed to define the putative interaction sites and their accessibility for the biologically important metals of Irving William Series.Key findingsSeveral hotspot residues in the ZAG scaffold involved in these interactions were mapped and their binding affinity score for each metal has been determined. Their binding abilities of these sites and aggregation propensities of ZAG were monitored by fluorescence emission spectroscopy.SignificanceThe prediction of such binding affinity with metals on the active sites and its impact on the c...

Conclusions Preoperative serum TC level is an independent poor prognostic factor for patients with surgically treated RCC, with lower levels associated with worse CSS and PFS. Hence, this parameter may provide additional guidance in the selection of therapeutic strategies to improve prognosis, considering that cholesterol is a broadly applied routine marker in clinical practice.

In the UK, ovarian cancer is the sixth most common cancer in females*. A new study has found evidence to suggest that statins could lower the risk of women developing ovarian cancer. The research led by the University of Bristol, and funded by Cancer Research UK, is published today [18 February] in JAMA.

Type 2 diabetes (T2D) is a metabolic disorder of insulin resistance — a reduced sensitivity to the action of insulin — which leads to high blood sugar, or hyperglycemia. Approximately 12% of American adults have T2D, and more than one-third of Americans have prediabetes, a precursor to T2D. This is a major public health concern, as T2D dramatically increases risk for heart disease, including heart attacks, atrial fibrillation, and heart failure. The development and progression of T2D is affected by many factors. Some, such as a person’s race/ethnicity, age, and gender cannot be modified. Others, including...
