The phrase "abnormal expression of molecules" is correct and usable in written English.
It can be used in scientific or medical contexts to describe a situation where molecules are produced or expressed in a way that deviates from the norm.
Example: "The study revealed an abnormal expression of molecules associated with the disease, indicating a potential biomarker for diagnosis."
Alternatives: "irregular expression of molecules" or "atypical expression of molecules".
Keratinocytes from these mice exhibited abnormal expression of adhesion molecules at both the protein and the mRNA levels.
The abnormal expression of these molecules could be relevant for the prognosis of CTCL, as it has been shown for other tumour entities [ 39].
Stromal impairment in SDS can be related to either the reduced expression of hematopoietic cytokines, the altered production of extracellular matrix or the abnormal expression of adhesion molecules necessary for the interaction between hematopoietic progenitors and stromal cells.
B cells in patients with IgG4-RD and pSS display a variety of abnormalities, including disturbed B cell subpopulations, abnormal expression of key signaling molecules, co-stimulatory molecules, and inflammatory cytokines.
Abnormal expression of cell surface molecules notably contributes to enhance tumor cell growth, survival, migration, and invasiveness [ 4].
Taken together, the data suggest that impaired glucose metabolism in pBmpr1aKO mice may be due to abnormal expression of genes that encode molecules in other unidentified molecular pathway(s), rather than the well-known regulators of insulin processing and secretion.
However, these latter assumptions should be considered purely speculative, as in our analysis we did not include information about other biological determinants, such as EGFR mutations or abnormal expression of other EGFR-driven downstream molecules, which may play a relevant role in EGFR-directed treatment selection.
On a molecular level, DGC is distinguished from the intestinal type on the basis of its abnormal expression of the cell-cell adhesion molecule E-cadherin [ 4].
Many tumours have been shown to activate blood coagulation through an abnormal expression of high levels of the procoagulant molecule TF.
Mononuclear macrophage infiltration and abnormal expression of inflammatory mediators including intercellular adhesion molecule-1 (ICAM-1), MCP-1, TGF-β1, can be observed in nephridial tissue in the early stages of diabetic nephropathy [ 15].
