This study examines the regulation of the human PRL (hPRL) gene promoter by intracellular calcium. Deletants of the 5'-flanking region of the hPRL gene and constructs consisting of the thymidine kinase promoter linked to the first or second proximal Pit-1 binding site were fused to the bacterial chloramphenicol acetyl transferase (CAT) reporter gene. With the complete 5-kilobase pair (kbp) hPRL promoter sequence the calcium channel agonist Bay K8644 induced a significant 2-fold increase in CAT reporter gene expression and the antagonist verapamil a 4.5-fold reduction, using GH3 cells cultured in physiological levels of calcium. The transcriptional response to calcium influx was similar with a series of 5'-deleted hPRL-CAT constructs including those that comprised the proximal (up to 740 bp) or distal (-1300- to -1700-bp) sequences alone. When treating cells cultured in low calcium conditions the induction with the hPRL promoter increased to 5-fold on the addition of exogenous calcium and Bay K8644. The pituitary-specific expression of the hPRL gene is conferred by the interaction of the pituitary-specific factor Pit-1 with several binding sites located in the 5'-flanking DNA, of which three are located in the proximal region. This suggested that Pit-1 binding sites may be involved in the calcium response.(ABSTRACT TRUNCATED AT 250 WORDS) [less ▲]

Expression of the tilapia growth hormone (tiGH) gene is pituitary-specific and controlled by intracellular cAMP levels. DNaseI protection experiments allowed us to identify four Pit-1 binding sites in the tiGH - 465/ + 19 region. Deletion and mutagenesis analysis revealed that the - 131/+ 19 region, containing two Pit-1 sites, or four copies of the most proximal site tiGHF1 fused to the heterologous Tk promoter, confer high level expression in rat pituitary cells and direct transcription in non-pituitary cells only after expression of rat Pit-1. We show that a tilapia pituitary factor specifically binds to site tiGHF1 and obtained a partial cDNA sequence coding for tilapia Pit-1. The cAMP stimulation is mediated by the proximal (- 131/- 31) promoter region. It is Pit-1-dependent and requires the tiGHF1 site. In addition, four copies of this site confer cAMP inducibility to the Tk promoter in GC cells. [less ▲]

The research presented here attempts to explore the fine-control of pitch during singing among accurate occasional singers and individuals whose singing reflects a Vocal Pitch Imitation Deficit (VPID). Most past research addresses individual differences at the level of entire sung notes or melodies. By contrast, in the present research we addressed whether VPID singers differ from accurate singers with respect to the way to reach, maintain, and stop a sung tone. In order to describe the “scoops” at the beginning and ends of tone, as well as other forms of instability, we adapted the model of Large et al. (2002), originally designed to model entrainment of timing during synchronization. This model was applied to 1461 notes performed by 12 VPID and 17 accurate singers from the database of Pfordresher and Mantell (2014). Finally, the parameter values across the VPID and accurate singers were compared. The results showed that the model fits tones performed by accurate and VPID singers similarly well. As expected, the median pitch across the entire sung note deviated from the target to imitate for VPID singers; at the same time, the proportion of these deviations that were overshoots (“sharp”) versus undershoots (“flat”) were the same for VPID and accurate singers (2/3rd under and 1/3rd above). Thus accurate and VPID singers differ in the magnitude but not the type of overall deviation they exhibit. Whereas no difference occurred between the singers regarding the direction of the scoop (up or down) at the start and the end of the tone, the amplitude of the scoops was significantly different between VPID and accurate singers. The present study highlights the difficulty of VPID singers to reach and stop a sung tone, which supports the hypothesis of a fine motor control deficit in this population. Furthermore, the pitch fluctuations described by the model would have to be investigated in research on pitch accuracy perception. [less ▲]

Poor singing ability can be caused by poor pitch perception or by poor vocal-motor control. Many prior studies have tried to examine this relationship, but one factor that often fails to be taken into account is the timbre of the target to be matched. Here, we compare accuracy in instrumental and vocal pitch matching paradigms, designed such that each participant’s own voice serves as both the target and the response. Participants (nonmusicians) matched their previously recorded voice on a slider, designed to play back their voice at different pitch levels depending on the location of a finger press on a continuous dimension. They also matched single pitches with their voice, and sang a familiar melody (“Happy Birthday”) for comparison to the single pitch matching tasks. The nonmusicians were significantly better at instrumental pitch matching than vocal pitch matching, indicating that vocal-motor control is an important limiting factor on singing ability. There were significant correlations between the melodic singing ability and vocal pitch matching, but not instrumental pitch matching. People with higher quality voices tended to be more accurate with pitch in melodies. These results demonstrate that single pitch matching tasks can be useful in measuring general singing abilities, and further confirm the importance of vocal-motor control in determining singing ability.
