Sung-Hsin Kuo Our previous study demonstrated that administration of NVP-BEZ235 (BEZ235), a dual PI3K/mTOR inhibitor, before radiotherapy (RT) enhanced the radiotherapeutic effect in colorectal cancer (CRC) cells both in vitro and in vivo. Here, we evaluated whether maintenance BEZ235 treatment, after combinatorial BEZ235 + RT therapy, prolonged the antitumor effect in CRC. K-RAS mutant CRC cells (HCT116 and SW480), wild-type CRC cells (HT29), and HCT116 xenograft tumors were separated into the following six study groups: (1) untreated (control); (2) RT alone; (3) BEZ235 alone; (4) RT + BEZ235; (5) maintenance BEZ235 f...

Publication date: Available online 17 August 2019Source: BurnsAuthor(s): Feng Tian, Yiwen Niu, Yuzhi JiangAbstractScar often occurred during wound repair. It was known that there were differences in collagen structure in dermal tissues at millimeter scale and micron scale, however, it was not known whether there were differences in collagen structure in dermal tissues at nanoscale during wound repair. In order to compare the difference at nanoscale, skin samples from patients were selected, the control groups were the normal skin from the same patients. These samples were tested by the small angle X-ray scattering techniqu...

In conclusion, our data show how oncogenic and tumor-suppressive drivers of cellular senescence act to regulate surveillance processes that can be circumvented to enable SnCs to elude immune recognition but can be reversed by cell surface-targeted interventions to purge the SnCs that persist in vitro and in patients. Since eliminating SnCs can prevent tumor progression, delay the onset of degenerative diseases, and restore fitness; since NKG2D-Ls are not widely expressed in healthy human tissues and NKG2D-L shedding is an evasion mechanism also employed by tumor cells; and since increasing numbers of B cells express NKG2D ...

Here, we report guanosine quartet hydrogels loaded with recombinant human-source collagen (G4-RHC) that can be used as medical patches for wound repair. The G4-RHC hydrogels are flexible, and when wrapped onto the skin s...

Hollingsworth, Katherine Julian, Jaime ImitolaAbstractHuman central nervous system (CNS) regeneration is considered the holy grail of neuroscience research, and is one of the most pressing and difficult questions in biology and science. Despite more than 20 years of work in the field of neural stem cells (NSCs), the area remains in its infancy as our understanding of the fundamental mechanisms that can be leveraged to improve CNS regeneration in neurological diseases is still growing. Here...
