Vasa

Vasa (väˈzə), Pol. Waza, royal dynasty of Sweden (1523–1654) and Poland (1587–1668). Gustavus I, founder of the dynasty in Sweden, was succeeded by his sons Eric XIV (reigned 1560–68) and John III (reigned 1568–92). John III married the sister of Sigismund II of Poland, and their son was elected (1587) king of Poland as Sigismund III. On John's death Sigismund succeeded to the Swedish throne, but his Catholicism led to his deposition (1599) in Sweden, where his uncle Charles IX (reigned 1604–11) succeeded him. The house was thus split into a senior Catholic line (in Poland) and a cadet Protestant line (in Sweden), and the two lines engaged in chronic warfare. Charles IX of Sweden was succeeded by Gustavus II; on Gustavus's death (1632) his daughter Christina ascended the throne. With Christina's abdication (1654) in favor of her first cousin, Charles X, the Swedish throne passed to the Zweibrücken line of the house of Wittelsbach. In Poland, Sigismund III was succeeded (1632) by his son Ladislaus IV, who was succeeded (1648) by his brother John II. John abdicated in 1668.

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).

We investigated the expression of genes related to the specification and appearance of early stages of primordial germ cells in humans (KIT, UTF1, LIN28, and DDX4) and genes related to gonadal somatic cells (CYP11, SOX9, SCF, StAR, and SF1) as well as genes expressed in undifferentiated hES cells and related to the NODAL pathway (EBAF, LEFTB, NODAL, and TDGF1), which plays a major role in early cell fate, including germ-cell specification and endoderm specification as well as maintenance of the pluripotent status of stem cells [26].

In the pi-body, the complex interacts with mouse vasa homolog Mvh RNA helicase (DDX4).
TDRD12 was not co-localized with either DDX4 or TDRD1 during spermatogenesis.
Real time PCR analysis: Expression of germ cell specific genes such as OCT4, STELLA, SCP3 and DDX4 was detected in treated and control hUCMSC groups by Real time PCR analysis.
The transcription factors such as DDX4 were expressed in post-migratory primordial germ cells until the premeiotic stage of germ cells.
The addition of exogenous factors such as BMP-4, BMP-7 and BMP-8 to stem cell cultures increases the number of germ cells expressing DDX4, but does not necessarily induce their progress in meiosis (25).
Real time PCR analysis of the stem cell markers DDX4 and SSEA-4, which are potent germ cell markers as well, could be clearly detected in PGC like cells, whereas the primary hUCM-SC cell populations showed only faint staining for these markers.
MEASUREMENT OF DIFFERENT PARTS OF ACTB AND DDX4 mRNAs
We extracted RNA from 0.4 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.
