Table_1_FGFR4 Gly388Arg Polymorphism Reveals a Poor Prognosis, Especially in Asian Cancer Patients: A Meta-Analysis.docx
The fibroblast growth factor-4 receptor (FGFR4) is a member of receptor tyrosine kinase. The FGFR4 Gly388Arg polymorphism in the transmembrane domain of the receptor has been shown to increase genetic susceptibility to cancers. However, its prognostic impact in cancer patients still remains controversial. Herein, we performed this meta-analysis to evaluate the clinicopathological and prognostic impacts of the FGFR4 Gly388Arg polymorphism in patients with cancer. We carried out a computerized extensive search using PubMed, Medline, and Ovid Medline databases up to July 2021. From 44 studies, 11,574 patients were included in the current meta-analysis. Regardless of the genetic models, there was no significant correlation of the FGFR4 Gly388Arg polymorphism with disease stage 3/4. In the homozygous model (Arg/Arg vs. Gly/Gly), the Arg/Arg genotype tended to show higher rate of lymph node metastasis compared with the Gly/Gly genotype (odds ratio = 1.21, 95% confidence interval (CI): 0.99-1.49, p = 0.06). Compared to patients with the Arg/Gly or Arg/Arg genotype, those with the Gly/Gly genotype had significantly better overall survival (hazard ratios (HR) = 1.19, 95% CI: 1.05-1.35, p = 0.006) and disease-free survival (HR = 1.25, 95% CI: 1.03-1.53, p = 0.02). In conclusion, this meta-analysis showed that the FGFR4 Gly388Arg polymorphism was significantly associated with worse prognosis in cancer patients. Our results suggest that this polymorphism may be a valuable genetic marker to identify patients at higher risk of recurrence or mortality.</p
Robust Heteroepitaxial Growth of GaN Formulated on Porous TiN Buffer Layers
Gallium nitride (GaN) heteroepitaxial growth is widely
studied
as a semiconductor material due to its various benefits. Especially,
development of a buffer layer between GaN and the substrate verifies
to be an effective strategy to reduce high threading dislocation density.
However, the buffer layer often impedes strong adhesion between the
epilayer and foreign substrate because thermally induced residual
stress often causes delamination of the epilayer during fabrication.
Here, we developed a robust GaN heteroepitaxy employing a porous buffer
layer formulated by hydride vapor phase epitaxy. A sufficiently low
but completely coated thin Ti layer was deposited on the sapphire
substrate, which led to a rough and porous TiN layer after nitridation.
This porous structure enables the penetration of the GaN source into
the porous structure, allowing GaN epitaxy initiation throughout the
TiN layer. As a result, GaN crystal growth can fill the porous area
during the GaN heteroepitaxy. Integrated visualization demonstrated
that the voids were successfully removed by GaN infiltration, enabling
the heteroepitaxial structure to show little deformation, confirmed
by multiple indentations. Last, the void-free GaN heteroepitaxy with
the porous TiN buffer layer displayed robust adhesion after delamination
