<pubmed>24590292</pubmed> | |||
Cleft lip is one of the common craniofacial birth defects that the upper lip is failed to fuse. There are many genes are involved of this disease but the pathogenesis of this disease is undergoing researches. The team found that Hhat encodes an acyltransferase that is responsible for modifying hedgehog (HH) proteins through the addition of palmitic acid. Disruption of Hhat diminishes palmitoylation of SHH, which means the production of acyltransferase is decreased and leads the HH protein failed to be modified. On the other hand, this team also found that the mutation of Ptch1 gene causes an enhanced signing of Sonic hedgehog (SHH) and leads cleft lip and palate. The mixing of these two mutation shows normal level of HH signalling but also show the cleft lip and palate. | |||
The team mentioned that during nasal process fusion epithelial cells need to be removed in order to form a mesenchymal bridge which is critical for a rigid connection in the developing lip and primary palate. The individual with mutation of Hhat or Ptch1 gene lack the ability to remove ECAD-positive epithelial cells from the tip of developing processes. | |||

'''What is/are the dystrophin mutation(s)?''' | |||
Duchenne muscular dystrophy is the most common muscle disease in new born male because DMD is X-linked recessive disorders that are caused by mutation of the DMD gene located at Xp21 and male only have one X chromosome while another one must be Y chromosome. Due to female have two X chromosome thus this recessive gene has a lower chance to be expressed in female. <ref name="PMID22379338"><pubmed>22379338</pubmed></ref> | |||
The majority of identified mutations of DMD are deletions, about 60%-65% in all cases, follewed by duplications with 5%-15% occurence. The remaining cases may be caused by small mutations such as microdeletions, microinsertions, point mutations, or splicing mutations. <ref name="PMID22379338"/> | |||
'''What is the function of dystrophin?''' | |||
One of the function of dystrophin in the muscle is to protect muscle fibres against the mechanical forces of contraction and stretching, and thus its absence renders muscle fibres susceptible to stretch-induced damage and necrosis, which means the death of muscle cells and lost its functions.<ref><pubmed>26081639</pubmed></ref> | |||

- References part is messy, more detail could be found in editing links. | |||
- Add pictures, pictures are easier way to understand the topic. | |||
-Table could be used for "WnT-Calcium Ion Pathway" part. | |||

Only needs to fill the gaps in the page and try to add more pictures to help the audience understand the topic, especially for the abnormality of this signalling. | |||
====GP4 peer review==== | |||
This group had found some good animal of their project. Very detailed content in each section but it seems a bit meticulous and even messy, sub-titles should be added to be systematically and clear. Good references formatting. This group have left some area that to be posted such as history, function and glossary, they should be as much as the existed part to be more balanced. We could find the abnormality part under some titles, I think this group group member could add an abnormality part the list out the disease related to this signalling. More picture should be added to help audience to understand the topic, there is the only one in the beginning. | |||

Introduction had explained what does this signalling pathway do and importance and page outlining. Followed by history part but seems more would be added. Pictures and table are used to assist explanations. Detailed content but seems need sub-heading or spacing ( formatting). Some gap parts are found. If the abnormality could be linked to the table above would be better. Quiz part is made but needs questions. Some pending glossary are found. Good references formatting. | |||

'''A brief summary of the research paper's main findings:''' | |||
The research team found that zebrafish could regenerate the heart from 20% lost of the ventricle. From the observation in an explant culture, the concentration of pdgfrβ, a kind of mural and mesenchymal cell markers, is increased in the regenerating hearts. The team summarized that platelet-derived growth factor (PDGF) signaling is responsible for epicardial cell proliferation. PDGF also tend to loss of cell to cell communication of epicardial cells in explant culture. The inhibition of PDGF signaling caused the sample having impaired in epicardial cell proliferation, expression of mesenchymal and mural cell markers, and coronary blood vessel formation. Without hte expression of mesenchymal and mural cell markers or pdgfrβ, the sample mice shows abnormal clustering of endothelial cells, absence of epicardial-derived smooth muscle cells, and defective coronary artery formation, which determined the important role of PDGF. | |||
'''Then describe how the original research result was used in the review article:''' | |||
The review article cited the above research article when introducing the participation of non-muscle cell type in the heart regeneration of injury induced animal models and is listing out the factors required for heart regeneration. The article said that epicardial cell is responsible for cardiac wall formation and the signaling by PDGF could increase the activity of epicardial cell behavior and coronary vessel formation to support the heart regeneration. | |||

High Serum FSH is Associated with Brown Oocyte Formation and a Lower Pregnacy Rate in Human IVF Parctice
By Hongyi Xu, Kai Deng, Qingbing Luo, Juan Chen, Xin Zhang, Xiaoyan Wang, Honglu Diao, Changjun Zhang
It is been trusted by the research team that the probability of successfully implantation is proportional to the quality of the oocyte that forms embryo, especially in in vitro fertilization since to increase the rate of success. Thus the examination of quality of oocyte is vital for IVF. The quality of embryo could be depended on varied features of the oocyte. However there is no formal and confirmed agreement of the effects of morphological anomalies of oocyte and their potential effects. One of the anomalies, the brown oocyte that show brown or black color in the zona pellucida (ZP) others than the normal oocyte shows pale colors, had been chosen as the independent variable for the research while keeps other features as same conditions. The outcomes, including the physical conditions and hormone level of mother during pregnancy and the rate of fertility, will be compared. The result shows that there is no significant changes about the status of the mother between the normal oocyte and brown oocyte. However it has been found that the high level dosage of FSH serum used in order to accelerate the maturation of the follicle leads to the infertility in certain reasons related to the development of the oocyte.
Mark Hill 18 August 2016 - You have not added the citation correctly, the brief written summary of the article findings is good. I guess I am wondering what a znal pellucid that makes a "Brown Oocyte" actually is?
