Theory arguing that some mutations are selected because they are beneficial to early-life fitness but become harmful later in life, thus causing ageing. Clonal expansion The production of daughter cells from a single parent cell, all sharing a particular characteristic or trait.Rights...

Under the first model (a), mutations with high fitness are rare within the subset of mutations that are evolutionarily plausible. Under the second model (b), when restricted to the regime of plausible mutations, improvements to fitness become much more common. c, Protein language models, ...
This should be detrimental to offspring.Proposed : Sex is group-selected in prey to allow coalescence of beneficial, and disposal of detrimental, mutations in single individuals enabling rapid adaptation to novel predation. Group selection is a universal force driven by local inter-species (not ...
A higher expression of MGAM has been noted in luminal A breast cancers, and a meta-analysis identified that MCAM mutations are associated with a positive clinical benefit in non-small lung cancer cases [45, 46]. It is thus a promising focus for future glycolytic and cancer investigations. ...
Subramanian To the Editor: Recently the useff fulness of snake venom preparation in the treatment of drugfresistant human immunodeficiency virus was demonstrated in clinical pracff tice for the first time by Alrajhi and Almohaizeie.[sup] [1] This represents an emerging concept in the era......
That apart, the duplicates may either diverge at the subcellular protein localization [17] or share the ancestral function [18] after complementary degenerative mutations (subfunctionalization) [19] or adapt to new functions (neofunctionalization) [2]. Furthermore, there are also subtle differences ...
These preliminary results are consistent with our hypothesis that the beneficial effect of UDC on PBC may involve decreased apoptosis after GUDC uptake by cholangiocytes. 展开 关键词: Bile Ducts Cell Line Mitochondria Humans Taurocholic Acid Depsipeptides Ursodeoxycholic Acid Cytochrome c Group Caspases...
, confirming that WT organoids actively secrete VLDL particles. Fig. 2: Organoid models of DNL-generated lipid accumulation by introduction ofAPOBorMTTPmutations. a, Workflow used to perform lipidomics on organoid cultures.b, PCA on neutral lipids found in the supernatant of WT organoids and ...
Here we show that human phenotypes associated with loss of function GPR10 mutations include anxiety, depression, impaired memory and impaired pain sensation (Table 1). While gaps in understanding remain, these observations suggest that GPR10 agonism may have beneficial effects on anxiety, depression ...
