Mechanisms of Cellular Internalization of Quantum Dot® Conjugated Bone Formation Mimetic Peptide CK2.3.
Article in Nanomaterials (Basel, Switzerland), 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Osteoporosis is a debilitating skeletal disorder that is characterized by loss of bone densityover time. It affects one in two women and one in four men, age 50 and older. New treatmentsthat specifically drive bone formation are desperately needed. We developed a peptide, CK2.3, thatacts downstream of the bone morphogenetic protein receptor type Ia and it induces osteogenesisin-vitro and in-vivo. However, its mechanism of action, especially its mode of uptake by cellsremains unknown. To demonstrate CK2.3 internalization within a cell, we conjugated CK2.3to Quantum Dot®s (Qdot®s), semiconductor nanoparticles. We purified CK2.3-Qdot®s by sizeexclusion chromatography and verified the conjugation and stability using UV/VIS and Fouriertransform infrared spectroscopy. Our results show that CK2.3 was conjugated to the Qdot®s andthe conjugate was stable for at least 4 days at 37 °C. Moreover, CK2.3-Qdot®s exerted biologicalresponse similar to CK2.3. Addition of CK2.3-Qdot®s to cells followed by confocal imaging revealedthat CK2.3-Qdot®s were internalized at 6 h post stimulation. Furthermore, using pharmacologicalinhibitors against endocytic pathways, we demonstrated that CK2.3-Qdot®s were internalized bycaveolae. These results show for the first time that the novel peptide CK2.3 is taken up by the cellthrough caveolae mediated endocytosis.
