As citas no texto realízanse inserindo unha secuencia de números consecutivos, seguindo a orde en que se mencionan por primeira vez no texto. No caso de citar a mesma fonte en varias ocasións, usaráse sempre o mesmo número para identificala.
Os números serán arábigos e irán entre paréntese:
In a previous study (1), we identified synaptic cell adhesion molecule 1 (SynCAM1) as a subordinate gene of a regulatory gene network postulated to operate in the hypothalamus. It was postulated that the main function of this network is to facilitate and integrate cellular and cell-cell communication programs required for the acquisition of female reproductive competence (1, 2). The network is composed of genes that control diverse cellular function but share the common feature of having been earlier identified as involved in tumor suppression/tumor formation. SynCAM1, also known as nectin-like protein 3 (Necl2) or Ig superfamily4 (IGSF4), was originally described as tumor suppressor in lung cancer-1 (TSLC1) (3, 4).

Septins are a conserved family of cytoskeletal GTP-binding proteins that function in cytokinesis, cell polarity, and membrane remodeling in many eukaryotic cell types [1, 2]. To contribute to these diverse process, septins polymerize into filaments and higher-order structures that organize the cell cortex into domains that are tightly controlled in time and/or space [3].
