The phrase "a deficient expression of" is correct and usable in written English.
It can be used to describe something that inadequately conveys a particular idea or sentiment.
Example: "The poem was a deficient expression of the author's true feelings about love."
Alternatives: "an inadequate representation of" or "a poor reflection of".
Accordingly, a deficient expression of one of its receptors, VPAC1, has been reported in patients with Rheumatoid Arthritis and this appeared to correlate with polymorphisms at the 3'-UTR of the gene [18].
Tao et al. described an increased susceptibility of NKT cells to apoptosis via CD95-CD95L or TCR-CD3 in NKT cells isolated from active SLE patients, and linked it with a deficient expression of CD226 [ 30].
There is high morphologically agreement with another case of EBJ in this breed [ 18] in which, based on immuno-histological examination, a deficient expression of integrin α6β4 was hypothesised as being a possible cause.
It was demonstrated in this study, that in 8 out of 20 SCC of cervix a deficient expression of the RAR-β2 mRNA was observed in comparison to the matched morphologically normal tissue of cervix.
Immune tolerance for self-antigens can be disrupted by defective elimination of autoreactive thymocytes that have a deficient expression of the proapoptotic protein Bim [ 90], mutations on the tyrosine kinase ZAP-70 signaling [ 91] or the depressed expression of the Mer tyrosine kinase [ 92].
The level of the expression of RAR-β2 mRNA was evaluated in 20 samples of invasive squamous cell carcinomas of uterine cervix at low and moderate levels of differentiation and in the morphologically normal tumor-adjacent tissues of cervix in order to select a group of tumors with deficient expression of RAR-β2.
Finally, SNPs in the TBP-binding sites invariantly cause gene overexpression in relation to SNP-caused enhancement of the TBP/promoter affinity as well as the deficient expression of genes as a result of an SNP-caused reduction in this affinity regardless of any cellular conditions; these phenomena have been repeatedly demonstrated in independent experiments [ 39– 41].
Friedreich's ataxia (FRDA) is a degenerative inherited disease because of deficient expression of the nuclear-encoded mitochondrial protein frataxin.
The CNS normally is in an immunologically quiescent state, due to deficient expression of MHC molecules, and limited entry of infiltrating T-cells into the brain parenchyma.
Deficient expression of PPARγ can be a significant risk factor for carcinogenesis, although in some cases overexpression enhances carcinogenesis.
In contrast with colorectal cancer, we did not see any evidence of an improved prognosis in the subset of patients with deficient expression of MMR proteins.
