Samsung has reportedly decided to 'freeze' Galaxy S25 series prices at the eleventh hour. It took a year, but T-Mobile's Hulu promo is finally coming through for grandfathered users. Leaked Galaxy S25 Ultra images seem to confirm Samsung's self-sabotaging move. Leaked T-Mobile document suggests some users might have more price hikes in their future.
Samsung Galaxy S25 prices won't increase and that's not a good thing.
Kunimasa suzuki biography of nancy sinatra: Here we show that TMEM55A, a lipid phosphatase that dephosphorylates phosphatidylinositol-4,5-bisphosphate (PIP2) to phosphatidylinositolphosphate (PI5P), regulates α-cell exocytosis and glucagon secretion.
It may be too late for the Galaxy S25, but the S26 Ultra may finally come with the long-rumored battery-stacking tech. Latest News. Xiaomi 15 gets a festive makeover with a new color option. Sleek Galaxy Z Flip 6 gets a fantastic price cut, making it a top choice for foldable fans.

In his leisure time, Suzuki enjoys discovering new wine pairings, golfing, and photography. He candidly shares that the two pieces of advice above also apply to how he pursues these hobbies. When discussing Intel Japan as a choice for both professionals and fresh graduates, Suzuki enthuses:. As a leading technology player in Japan, Intel is distinguished by our unique positioning: our perspective has always been one of growing industries and building social infrastructure through business operations, rather than selling products.
However, the inhibitory role of tomosyn does not only depend on syntaxin binding Therefore, we sought to identify additional tomosyn1-interacting proteins. We detected 88 tomosyn1-interacting proteins Table S1. Additionally, native secretagogin is pulled down with native tomosyn in isolated human islets Fig. Tomosyn and secretagogin interaction decreases in response to insulin secretagogues.
Secretagogin was initially cloned from neuroendocrine and pancreatic islet cells 21 , and we confirm that expression of secretagogin in human pancreas is limited to insulin- and glucagon-positive cells Fig. Similar secretagogin expression was also observed in mouse islets Fig. Although secretagogin is reduced in islets from GK diabetic rat 23 , high-fat fed mice 24 , and isolated islets exposed to high glucose 25 , we find that secretagogin mRNA Fig.
S2c,d ; Table S2 or immunostaining Fig. S2i between donors with and without type 2 diabetes T2D was not different. We also observed no correlation between secretagogin mRNA levels and glycaemia Fig. S2e,f or body mass index Fig. Thus, the expression of secretagogin is not altered in islets from donors with T2D. Given that the interaction between secretagogin and tomosyn is regulated by glucose and KCl, we explored the role of secretagogin in insulin secretion.
Insulin content Fig. Accordingly, knockdown of secretagogin impaired the ability of glucose to facilitate depolarization-induced exocytosis. Glut2: Glucose transporter.

Here we show that the post-translational modification of tomosyn by SUMO1 is required for syntaxin1A binding and inhibition of insulin exocytosis. Post-translational modifications play a key role regulating assembly of the exocytotic machinery 13 and SUMO1 in particular controls insulin exocytosis in response to metabolic signals, likely by regulating events at the plasma membrane 4.
Consistent with these observations, we showed that tomosyn is modified by SUMO1, is de-SUMOylated upon glucose-stimulation, and this controls its interaction with syntaxin1. Therefore, the de-SUMOylation of tomosyn alleviates its inhibitory function, possibly by favoring the displacement of syntaxin1A to interact with SNAP25, a key step required for the formation of the minimal exocytotic complex 5.
Another proposed model has suggested that tomosyn inhibits exocytosis through the formation of tomosyn-SNAP25 complexes 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , In contrast to previous observations in islets from diabetic GK rats 23 , high fat fed mice 24 , and in islets exposed to chronic high glucose 25 , we did not observe any alteration of secretagogin levels, either mRNA or protein, in islets from human T2D donors.
This is consistent with recent studies showing that the secretagogin controls insulin secretion from MIN6 26 and NIT1 cells In agreement with the observation that secretagogin controls F-actin filament remodeling, glucose-induced focal-adhesion, and TAU protein that controls microtubule dynamics 27 , 28 , we find that secretagogin is required for the glucose-dependent recruitment of insulin granules to the plasma membrane.
We find the absence of a putative SIM domain on secretagogin Fig. S2k , suggesting that secretagogin is more likely not binding to the SUMOylated motif of tomosyn Fig. We thus propose Fig. Diabetes status was determined by patient clinical history and by HbA1c measurement we determine undiagnosed T2D if HbA1c is higher that 7. A detailed list of donors is provided in Table S2.
The collection of, and experiments on, human tissue were approved by the Human Research Ethics Board Pro at the University of Alberta, and all experiments were carried out in accordance with relevant guidelines and regulations at the University of Alberta.

Donors or their relatives provided written informed consent to the use of pancreas tissue for research. Chris Newgard Duke University , were cultured as described 3. Burlington, ON. Normal mouse and goat serum was used as negative control. Immunprecipitated proteins were eluted in 3X laemmeli buffer. Insulin content was extracted with acid-ethanol solution 1.
Rockville, MD. Single green cells were used for whole-cell patch-clamp measurement of exocytosis as described previously 3.
Immunofluorescence of human and mouse pancreas sections were performed and quantified as previously described 3. Data analysis was performed using GraphPad Prism v6. A P value less than 0. MacDonald, P. Prentki, M.
