Role of microRNA508-3p in melanogenesis by targeting microphthalmia transcription factor in melanocytes of alpaca

open access: yesAnimal, 2017
It has been demonstrated that microRNAs (miRNAs) play important roles in the control of melanogenesis and hair color in mammals. By comparing miRNA expression profiles between brown and white alpaca skin, we previously identified miR508-3p as a ...

Genome-Wide Association Study of Fiber Diameter in Alpacas

open access: yesAnimals, 2023
The aim of this study was the identification of candidate genomic regions associated with fiber diameter in alpacas. DNA samples were collected from 1011 female Huacaya alpacas from two geographical Andean regions in Peru (Pasco and Puno), and three ...

Construction of two whole genome radiation hybrid panels for dromedary (Camelus dromedarius): 5000RAD and 15000RAD [PDF]

open access: yes, 2018
The availability of genomic resources including linkage information for camelids has been very limited. Here, we describe the construction of a set of two radiation hybrid (RH) panels (5000RAD and 15000RAD) for the dromedary (Camelus dromedarius) as a ...

Effects of orexins on 17β-estradiol synthesis and P450 aromatase modulation in the testis of alpaca (Vicugna pacos). [PDF]

open access: yes, 2018
The steroidogenic enzyme P450 aromatase (ARO) has a key role in the conversion of testosterone (T) into estrogens (E), expressed as 17β-estradiol. The presence and localization of this key enzyme have not been described before in the South American ...

High Redshift Standard Candles: Predicted Cosmological Constraints [PDF]

open access: yes, 2014
We investigate whether future measurements of high redshift standard candles (HzSCs) will be a powerful probe of dark energy, when compared to other types of planned dark energy measurements.

Bacterias fibrolíticas aisladas de rumen de alpaca, ovino y vacuno con capacidad biodegradadora de celulosa

open access: yesRevista Científica, 2022
Las bacterias ruminales celulolíticas se utilizan en la alimentación de rumiantes por su capacidad biodegradable de forrajes fibrosos. Sin embargo, existen escasos estudios en alpaca, ovino y vacuno si constituyen fuentes de microrganismos degradadores ...

Resistance to compression behavior of alpaca and wool

open access: yes, 2004
This study compares the resistance to compression behavior of wool and alpaca fibers. It shows that alpaca fibers have a much lower resistance to compression than wool, and there is little correlation between the resistance to compression and the ...
