Lipid accumulation facilitates mitotic slippage-induced adaptation to anti-mitotic drug treatment

Published date : 27 Nov 2018

Aberrant lipid accumulation is a hallmark of cancer known to contribute to its aggressiveness and malignancy. Emerging studies have demonstrated context-dependent changes in lipid metabolism during chemotherapy. However, there is little known regarding the mechanisms linking lipid metabolism to chemotherapy-induced cell fates. Here, we describe lipid accumulation in cells following antimitotic drug treatment. Cells arrested in mitosis, as well as cells that escaped mitotic arrest and underwent mitotic slippage, showed elevated cytoplasmic lipid droplets.

Potent tocolytic activity of ethyl acetate fraction of Ananas comosus on rat and human uteri

Published date : 18 Jun 2018

The aim of this study was to investigate the tocolytic properties of Ananas comosus extract in rat and human uterine tissue in vitro and in the rat in vivo. Organ bath technique was employed to perform functional studies in vitro. The PhysioTel transmitter was implanted in SD rats to measure the changes in intrauterine pressure (IUP) in vivo. Analyses of F2 was performed using LC-HRMS.

Isolation and Identification of an Anthracimycin Analogue from Nocardiopsis kunsanensis, a Halophile from a Saltern, by Genomic Mining Strategy

Published date : 21 May 2018

Modern medicine is unthinkable without antibiotics; yet, growing issues with microbial drug resistance require intensified search for new active compounds. Natural products generated by Actinobacteria have been a rich source of candidate antibiotics, for example anthracimycin that, so far, is only known to be produced by Streptomyces species. Based on sequence similarity with the respective biosynthetic cluster, we sifted through available microbial genome data with the goal to find alternative anthracimycin-producing organisms.

Role of the serotonergic pathway in uterotonic activity of Ananas comosus (L.) Merr. – An in vitro and in vivo study

Published date : 08 May 2018

Background
Ananas comosus (L.) Merr. has been used as a traditional medicine in inducing abortion in many countries. Our previous in vitro experiments showed that the aqueous fraction (F4) of A. comosus extract stimulated the rat and human uterine contractions.

Purpose
The aim of this study was to identify the bioactive compound and further investigate the molecular mechanism of F4 induced contraction and the in vivo uterotonic effect of F4.
