Article Abstract

One of the best-kept secrets by fungi especially yeast is the function of the different shapes and surface structures of their vegetative and sexual cells. They definitely do not produce these shapes (e.g. round, elongated, kidney, needle, hat, saturnoid, etc.) and surfaces (e.g. smooth, rough, hairy, warty, etc.) for our curiosity or to be classified, but surely produce these for their own benefit. This mini-review will show that a large variety of 3-hydroxy oxylipins are widely distributed in the fungal domain and closely associated with these surface ornamentations. In concert with nano-scale surface structures, they probably play a role in cell aggregation as well as spore release from sexual structures such as asci.

The saponins of had many pharmacological activities such as antitumor, antioxidation, and blood sugar lowering, which were synthesized by two pathways: mevalonate (MVA) and methylerythritol phosphate (MEP). 3-Hydroxy-3-methylglutaryl coenzyme A synthase (HMGS) was the key enzyme in the MVA synthesis pathway, and its expression level may affect the accumulation of saponins which were the main active ingredients of . In this study, we successfully cloned and from and their sequence similarity was 93.

Monohydroxylated polyunsaturated fatty acids belonging to the oxylipin class of natural products are present in marine and terrestrial sources as well as in the human body. Due to their biological activities and role in diverse biosynthetic pathways, oxylipins biosynthesized from eicosapentaenoic acid and arachidonic acid have attracted great interest from the scientific community. One example is 3-hydroxyeicosapentaenoic acid where the absolute configuration at C-3 has only been tentatively assigned.

Jasmonates (JA) are oxylipin-derived phytohormones that trigger the production of specialized metabolites that often serve in defense against biotic stresses. In , a JA-induced endoplasmic reticulum-associated degradation (ERAD)-type machinery manages the production of bioactive triterpenes and thereby secures correct plant metabolism, growth, and development. This machinery involves the conserved RING membrane-anchor (RMA)-type E3 ubiquitin ligase MAKIBISHI1 (MKB1).

Article Synopsis
  • Early life maternal separation (MS) in rats can lead to increased susceptibility to depression when combined with chronic mild stress (CMS).
  • N-3 polyunsaturated fatty acids (PUFA) showed potential in alleviating depressive behaviors primarily through the serotonergic pathway and had greater impacts when administered throughout the rats' lifetime compared to only during certain developmental periods.
  • The study found that n-3 PUFA supplementation resulted in significant changes in brain chemistry, decreasing stress hormone levels and inflammatory markers, while enhancing serotonin and other neuroprotective factors associated with improved mood.
