The phrase "alteration for which" is correct and usable in written English.
It can be used when referring to a specific change or modification that is being discussed or considered.
Example: "The alteration for which we are seeking approval will significantly improve the project's efficiency."
Alternatives: "change for which" or "modification for which".
The more stringent definition of the absence of segmental chromosome alterations, for which the status at all three chromosome arms had to be known, when compared with the definition of a segmental type, for which an alteration of any of the chromosome arms was sufficient, might lead to an underrepresentation of non-segmental cases.
It has been suggested that OSCC can arise in the course of accumulation of multiple genetic alterations [ 2], for which accurate molecular mechanisms regarding its pathogenesis remain to be understood.
Interestingly, each of the survival analyses described above (SNP, expression level, copy number changes) identified clinically relevant genomic alterations in genes for which cancer relevance is not presently established.
p53 gene mutation is the most common genetic alteration in neoplastic diseases, including breast cancer, for which p53 alteration may indicate poor prognosis.
Semax-induced upregulation of transcripts was observed for a majority of the immune-response genes; among these, immunoglobulin genes formed the most prominent group, with half of them exhibiting the highest amplitude of expression alteration among the genes for which the level of transcripts was affected by the peptide (Table 2).
The differences in phenotypes observed in the Esrp1 KO and Esrp1/Esrp2 DKO may therefore reflect splicing alteration in specific transcripts for which Esrp2 cannot fully compensate for loss of Esrp1 and/or be reflective of differences in Esrp2 levels in different epithelia.
We were interested in identifying the most realistic unit of the genome on which alterations likely arise and for which our multi-component model should be assessed statistically.
Despite all of these potentially confounding influences, gene coordination remains a strong influence on patterns of gene expression across areas, and for which alterations in depressed subjects correspond to known and suspected abnormalities in the illness.
Other concerns to be addressed in trials will be which mutations or epigenetic alterations should be analyzed for which tumor types, and in which patients.
