The reason for this response, Gordon says, was twofold: Firmicutes bacteria transplanted from the fat mice produced more of the enzymes that helped the animals extract more energy from their food, and the bacteria also manipulated the genes of the normal mice in ways that triggered the storage of fat rather than its breakdown for energy.

«By identifying the signals that instruct mouse progenitor cells to become cells that make tubes and later insulin - producing beta cells, we can transfer this knowledge to human stem cells to more robustly make beta cells, says Professor and Head of Department Henrik Semb from the Novo Nordisk Foundation Center for Stem Cell Biology at the Faculty of Health and Medical Sciences.
The researchers tested two anti-CK2 drugs for their ability to stimulate the production of new brown fat in mice: a new small - molecule CK2 - blocker called silmitasertib (CX - 4945), which is already in clinical trials as a cancer therapeutic; and a more precise next - generation antisense oligonucleotide (ASO) drug developed in collaboration with Isis Pharmaceuticals, which eliminates CK2 by blocking the RNA instructions cells use to produce it.
The most intriguing mutant type of mice were unusually thin; they generated more active osteocalcin, secreted more insulin, and produced many times more of the insulin - releasing cells in the pancreas.
Photoswitches inserted into retinal ganglion cells (RGC) of blind mice produce much less variety of response (all evenly red means the cells fire at the same time), while blind mice with photoswitches inserted into bipolar cells (ON - BC driven) exhibit much more variety in their retinal response to light, closer to that of normal mice.
Using mice, this study found that in obesity, CB1 cannabinoid receptors become enriched on the nerve terminals that normally inhibit orexin neuron activity, and the orexin neurons produce more of the endocannabinoids to activate these receptors.
Their answer, garnered through a series of electrophysiology, dendritic spine density and immunohistochemistry experiments with mice that were genetically altered to produce either more new neurons or kill off newborn neurons, supports the second model — some of the cortical neurons transfer their connections from mature granule cells to the new granule cells.
The full mouse connectome would produce hundreds of times more data than can be found on all of Google's computers, says Jeffrey Lichtman, the neuroanatomist leading the Harvard team.
«In our mouse experiments, olive oil produced essentially identical effects as Plenish — more obesity than coconut oil, although less than conventional soybean oil — and very fatty livers, which was surprising as olive oil is typically considered to be the healthiest of all the vegetable oils,» said Poonamjot Deol, an assistant project scientist working in Sladek's lab and the co-first author of the research paper.
So when Drake and his colleagues measured the RNA levels — a direct link to how much of a gene is being produced — in the genes of 334 mice, he didn't expect to find more than a few variations that might help explain why males and females have such different rates of cardiovascular disease and diabetes or why they react differently to certain drugs.
The team found lower levels of TRNP1 in areas that were destined to form folds, and higher levels in areas that would not have developed them, suggesting that the protein produced by the gene inhibits more complex brain development in humans as well as in mice.
In addition, substances called growth factors, produced naturally in the brain, were more abundant in key regions on both sides of the brain in optogenetically stimulated, stroke - affected mice than in their unstimulated counterparts.
In studies of neural development in mice, Stahl found that TRNP1 produces a protein that determines whether neural stem cells self - replicate, leading to a balloonlike expansion of cortical surface area, or whether they differentiate into a plethora of intermediate stem cell types and neurons, thickening the cortex and forming more complex brain structures.
When the total number of wheel revolutions was quantified during the 14 - hour data collection period, IL - 15Rα — KO mice produced 15,090 wheel revolutions (equivalent to 5.4 km), 6.3-fold more than the B6129 control mice (Figure 3B).
Similarly, we observed that male IL - 15Rα — KO mice produced 6.3-fold more wheel revolutions compared with B1629 control mice in cage wheel running experiments and had a larger number of ambulatory photobeam breaks in the light and dark cycles.
Multiple mouse models of SMA have been produced, generally by knocking out the endogenous mouse SMN1 gene and replacing it with one or more copies of the human SMN2 gene that produces much less full - length SMN protein than the SMN1 gene.
Reduction of htt to 50 % endogenous levels produces viable mice with no overt phenotypes (Duyao et al., 1995; Zeitlin et al., 1995) however more detailed evaluation has revealed deficits in cognition and motor behavior (Nasir et al., 1995) raising the possibility that lowered htt starting in development may have adverse effects in the mouse.
However, unlike the mouse, the zebrafish is smaller and can produce more offspring in a shorter time (200 eggs per week compared to a mouse litter of 15 pups in 21 days).
Researchers comparing normal and obese mice found that obese mice produced more than twice as much of a small microRNA molecule called microRNA - 143 in their liversANCHOR.
