Vasa

 

Swedish royal dynasty (1523-1654). The founder was Gustavus I Vasa (ruled 1523-60). His sons Eric XIV (1560-68) and John III (1568-92), his grandson Sigismund (1592-1604, in actuality until 1599), Gustavus’ son Charles IX (1604-11), Charles’ son Gustavus II Adolphus (1611-32), and the daughter of Gustavus II, Christina (1632-54) were all monarchs of Sweden. The Vasa dynasty also reigned in Poland from 1587 to 1668, including Sigismund III (1587-1632), who was the son of John III of Sweden and Catherine Jagello, the daughter of the Polish king Sigismund I the Old (with the election of Sigismund III as king of Sweden in 1592, the Swedish-Polish personal union that lasted until 1599 was established); and the sons of Sigismund III Ladislas IV (1632-48) and John Casimir (1648-68).

The academics, led by Dr Jonathan Tilly of Massachusetts General Hospital, managed to identify and extract human stem cells that can go on to become immature eggs, because all carry a unique protein called DDX4.
To characterize the concentration, integrity, and stability of cfsRNA, we selected the transcripts of 2 genes: ACTB (actin, beta) [5] and DDX4 [DEAD (AspGlu-Ala-Asp) box polypeptide 4], a germ cell-specific gene.
We used full-length PCR amplicons of human ACTB and DDX4 transcripts as calibrators to quantify their different regions.
MEASUREMENT OF DIFFERENT PARTS OF ACTB AND DDX4 mRNAs
In addition to measuring the size distribution of cfsRNA and detecting full-length transcripts, we further investigated the integrity of cfsRNA by quantifying the amounts of 5', middle, and 3' regions of ACTB and DDX4 transcripts via RT-qPCR analysis of 9 semen samples.
4 mL seminal plasma at each time point and then quantified each region of the ACTB and DDX4 transcripts by RT-qPCR.
To observe the effect of Triton X-100 on the stability of cfsRNA, we also added Triton X-100 (Sigma-Aldrich) to 5 other seminal samples and quantified the 5' region of ACTB and DDX4 mRNAs at different time points.
Early in human development, Smith explains, cells that eventually become part of the male or female reproductive system express two proteins, DDX4 and POU5fl.
