The chronological lifespan (CLS) of the budding yeast Saccharomyces cerevisiae is a model for the aging of post-mitotic cells in higher eukaryotes. In this study, we found that the sesquiterpene aryl ester melleolide expands the CLS of budding yeast. In contrast, melleolide compromised the CLS of the fission yeast Schizosaccharomyces pombe. This indicates that melleolide might have a potential anti-aging activity against some types of cell, and that it might be useful as a selective anti-fungal drug.

Article Synopsis
  • - The study investigates how caloric restriction (CR) influences the lifespan of yeast mutants with single gene deletions linked to key metabolic pathways like glycolysis, the TCA cycle, and the glyoxylate cycle.
  • - Results show that CR lengthens the chronological lifespan mainly in mutants tied to glycolysis and the TCA cycle, while no lifespan benefit is observed in mutants lacking essential enzymes for the glyoxylate cycle.
  • - Notably, CR boosts the activity of isocitrate lyase, an enzyme in the glyoxylate cycle, but rapamycin (a known lifespan-extending compound) does not enhance this enzyme's activity, indicating that CR operates through a unique metabolic pathway.

Unlabelled: Glucosylglycerol (GG) is an osmolyte that protects cells from extreme conditions. It is produced by sucrose phosphorylase, an enzyme that uses sucrose and glycerol as substrate. GG protects tissue integrity in desert plants during harsh conditions and guards cyanobacteria against high salinity (halotolerant).

FPR1 is essential for rapamycin-induced lifespan extension in Saccharomyces cerevisiae.

Biochem Biophys Res Commun

FK506-sensitive proline rotamase 1 protein (Fpr1p), which is a homologue of the mammalian prolyl isomerase FK506-binding protein of 12 kDa (FKBP12), is known to play important roles in protein folding and prevention of protein aggregation. Although rapamycin is known to bind to Fpr1p to inhibit Tor1p mediated-mechanistic Target Of Rapamycin (mTOR) activity, the physiological functions of Fpr1p on lifespan remain unclear. In this study, we used the eukaryotic model Saccharomyces cerevisiae to demonstrate that deletion of FPR1 reduced yeast chronological lifespan (CLS), and there was no benefit on lifespan upon rapamycin treatment, indicating that lifespan extension mechanism of rapamycin in yeast is exclusively dependent on FPR1.

Pathogenic Chlamydia species are coccoid bacteria that use the rod-shape determining protein MreB to direct septal peptidoglycan synthesis during their polarized cell division process. How the site of polarized budding is determined in this bacterium, where contextual features like membrane curvature are seemingly identical, is unclear. We hypothesized that the accumulation of the phospholipid, cardiolipin (CL), in specific regions of the cell membrane induces localized membrane changes that trigger the recruitment of MreB to the site where the bud will arise.

Prognostic and clinicopathological significance of cytocapsular tubes in oral squamous cell carcinoma.

J Oral Pathol Med

July 2022

Department of Oral and Maxillofacial Surgery, Hospital of Stomatology, Guanghua School of Stomatology, Sun Yat-sen University, Guangzhou, China.

Background: Cytocapsular tubes (CTs) provide membranous channels for cancer cells interconnection and multidirectional locomotion, which facilitate cancer cell transportation and metastasis. However, the clinicopathological significance of CTs has not been documented in oral squamous cell carcinoma (OSCC). Herein, we aimed to identify CTs and assess their clinicopathological significance in OSCC.
